One of the benefits of this standard practice is the ability to calibrate for the analysis of highly radioactive actinides using calibration standards at much lower specific activities (that is, 232Th and 238U). Environmental laboratories may find this standard practice useful if facilities are not available to handle the highly radioactive standards of the individual actinides of interest. The degree of actual mass bias is variable and is dependent upon instrument tune parameters. This standard practice uses universal interference equations to derive a mass bias correction that is specific to the instrument parameters and tune used for sample data acquisition and not based on a historical average. Mass bias correction uses the instrument software interference equations and does not require additional subsequent off-line calculations. The methodology that this standard practice is based on has been used for the determination of 232Th and 237Np in enriched uranium solutions and the determination of 241Am in plutonium and uranium legacy oxides following dissolution and ion extraction chromatography separation.1.1 This standard practice provides guidance for an alternate linear calibration for the determination of selected actinide isotopes in appropriately prepared aqueous solutions by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). This alternate calibration is mass bias adjusted using thorium-232 (232Th) and uranium-238 (238U) standards. One of the benefits of this standard practice is the ability to calibrate for the analysis of highly radioactive actinides using calibration standards at much lower specific activities. Environmental laboratories may find this standard practice useful if facilities are not available to handle the highly radioactive standards of the individual actinides of interest.1.2 The instrument response for a series of determinations of known concentration of 232Th and 238U defines the mass versus response relationship. For each standard concentration, the slope of the line defined by 232Th and 238U is used to derive linear calibration curves for each mass of interest using interference equations. The mass bias corrected calibration curves, although generated from interference equations, are specific to the instrument operating parameters and tuning in effect at the time of data acquisition. Because interference equations are part of the normal ICP-MS manufacturer's software package, this calibration methodology is widely applicable.1.3 For this standard practice, the actinide atomic mass range that has been studied is from amu 232-244. Guidance for an extended range of amu 228-248 is given in this practice.1.4 Using this practice, analyte concentrations are reported at each amu and not by element total (that is, 239Pu versus plutonium).1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This method is for determining the acid number of petroleum products, petroleum distillates, and other chemicals by potentiometric titration. Inorganic acids, organic acids, mercaptans and thiophenols respond to this analysis, but their respective salts do not; a procedure is also included for sodium naphthenate salts. The typical range for acid number detection is 0.002 to 5 mg KOH/g of sample, although higher levels can be accommodated. The acid number of a sample can be determined on an as-received basis or on a mercaptan-and thiophenol-free basis. The method can also be used to determine naphthenic acids including sodium naphthenates (soaps) in caustic-washed hydrocarbons. For an estimated relative molecular mass of 130, the range of detection for naphthenic acids is 5 to 500 mass-ppm. The latter two procedures apply almost exclusively to light kerosines and gas oils where it is assumed that the organic acids are entirely naphthenic.

1.1 Spectral searching is the process whereby a spectrum of an unknown material is evaluated against a library (database) of digitally recorded reference spectra. The purpose of this evaluation is classification of the unknown and, where possible, identification of the unknown. Spectral searching is intended as a screening method to assist the analyst and is not an absolute identification technique. Spectral searching is not intended to replace an expert in infrared spectroscopy. Spectral searching should not be used without suitable training.1.2 The user of this document should be aware that the results of a spectral search can be affected by the following factors described in Section : (1) Baselines, (2) sample purity, (3) Absorbance linearity (Beers Law), (4) sample thickness, (5) sample technique and preparation, (6) physical state of the sample, (7) wavenumber range, (8) spectral resolution, and (9) choice of algorithm.1.2.1 Many other factors can affect spectral searching results.1.3 The scope of this document is to provide a guide for the use of search algorithms for mid-infrared spectroscopy. The methods described herein may be applicable to the use of these algorithms for other types of spectroscopic data, but each type of data search should be assessed separately.1.4 The Euclidean distance algorithm and the first derivative Euclidean distance algorithm are described and their use discussed. The theory and common assumptions made when using search algorithms are also discussed, along with guidelines for the use and interpretation of the search results.

1.1 These practices cover a guide for the multivariate calibration of infrared spectrometers used in determining the physical or chemical characteristics of materials. These practices are applicable to analyses conducted in the near infrared (NIR) spectral region (roughly 780 to 2500 nm) through the mid infrared (MIR) spectral region (roughly 4000 to 400 cm-1).Note 18212;While the practices described herein deal specifically with mid- and near-infrared analysis, much of the mathematical and procedural detail contained herein is also applicable for multivariate quantitative analysis done using other forms of spectroscopy. The user is cautioned that typical and best practices for multivariate quantitative analysis using other forms of spectroscopy may differ from practices described herein for mid- and near-infrared spectroscopies.1.2 Procedures for collecting and treating data for developing IR calibrations are outlined. Definitions, terms, and calibration techniques are described. Criteria for validating the performance of the calibration model are described.1.3 The implementation of these practices require that the IR spectrometer has been installed in compliance with the manufacturer's specifications. In addition, it assumes that, at the times of calibration and of validation, the analyzer is operating at the conditions specified by the manufacturer.1.4 These practices cover techniques that are routinely applied in the near and mid infrared spectral regions for quantitative analysis. The practices outlined cover the general cases for coarse solids, fine ground solids, and liquids. All techniques covered require the use of a computer for data collection and analysis.1.5 These practices provide a questionnaire against which multivariate calibrations can be examined to determine if they conform to the requirements defined herein.1.6 For some multivariate spectroscopic analyses, interferences and matrix effects are sufficiently small that it is possible to calibrate using mixtures that contain substantially fewer chemical components than the samples that will ultimately be analyzed. While these surrogate methods generally make use of the multivariate mathematics described herein, they do not conform to procedures described herein, specifically with respect to the handling of outliers. Surrogate methods may indicate that they make use of the mathematics described herein, but they should not claim to follow the procedures described herein.1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This test method is intended for use in quality control, material screening, and related problem solving where a compositional analysis is desired or a comparison can be made with a known material of the same type. The parameters described should be considered as guidelines. They may be altered to suit a particular analysis, provided the changes are noted in the report. The proportion of the determined components in a given mixture or blend may indicate specific quality or end use performance characteristics. Particular examples include the following: 5.3.1 Increasing soot (carbon) content of used diesel lubricating oils indicates decreasing effectiveness. 5.3.2 Specific carbon-to-polymer ratio ranges are required in some elastomeric and plastic parts in order to achieve desired mechanical strength and stability. 5.3.3 Some filled elastomeric and plastic products require specific inert content (for example, ash, filler, reinforcing agent, etc.) to meet performance specifications. 5.3.4 The volatile matter, fixed carbon, and ash content of coal and coke are important parameters. The “ranking” of coal increases with increasing carbon content and decreasing volatile and hydrocarbon, (medium volatility) content.1.1 This test method provides a general technique incorporating thermogravimetry to determine the amount of highly volatile matter, medium volatile matter, combustible material, and ash content of compounds. This test method will be useful in performing a compositional analysis in cases where agreed upon by interested parties.1.2 This test method is applicable to solids and liquids.1.3 The temperature range of test is typically room temperature to 1000176;C. Composition between 1 and 100 weight % of individual components may be determined.1.4 This test method utilizes an inert and reactive gas environment.1.5 Computer or electronic-based instruments, techniques, or data treatment equivalent to this test method may also be used.Note 18212;Users of this test method are expressly advised that all such instruments or techniques may not be equivalent.

Auger electron spectroscopy yields information concerning the chemical and physical state of a solid surface in the near surface region. Nondestructive depth profiling is limited to this near surface region. Techniques for measuring the crater depths and film thicknesses are given in (35). Ion sputtering is primarily used for depths of less than the order of 1 μm. Angle lapping or mechanical cratering is primarily used for depths greater than the order of 1 μm. The choice of depth profiling methods for investigating an interface depends on surface roughness, interface roughness, and film thickness (1).3 1.1 This guide covers procedures used for depth profiling in Auger electron spectroscopy.1.2 Guidelines are given for depth profiling by the following:SectionIon Sputtering6Angle Lapping and Cross-Sectioning7Mechanical Cratering8Nondestructive Depth Profiling91.3 This standard does not purport to address all of the safety problems, if any, associated with its use.

1.1 This practice provides spectrophotometric methods for detecting the presence of fluorescence in object-color specimens.Note 18212;Since the addition of fluorescing agents (colorants, whitening agents, etc.) is often intentional by the manufacturer of a material, information on the presence or absence of fluorescent properties in a specimen may often be obtained from the maker of the material.1.2 This practice requires the use of a spectrophotometer that both irradiates the specimen over the wavelength range from 340 to 700 nm and allows the spectral distribution of illumination on the specimen to be altered as desired.1.3 Within the above limitations, this practice is general in scope rather than specific as to instrument or material.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

The solubility of organics is a basic physical parameter needed for the prediction of the fate of a chemical in the environment (6). The ionic strength and organic content of natural waters may cause an apparent decrease or increase from the value obtained in pure water. Data on this can be obtained in the laboratory by modifying the reagent water to simulate natural waters.1.1 This test method covers procedures for measurement of the solubility of organic compounds in water. Three procedures are described which will work over a variety of solubility ranges. These procedures are not appropriate for compounds that react with water or air at ambient conditions. 1.2 The procedure chosen will depend on the estimated solubility of the compound. This may be obtained from literature values (see Refs 1, 2, 3) by correlation with other parameters (4) or by analogy with the solubility of similar compounds. 1.3 This standard does not purport to address all of the safety problems, if any, associated with its use.

Accuracy in quantitative X-ray spectrometric analysis depends upon adequate accounting for interelement effects either through sample preparation or through mathematical correction procedures, or both. This guide is intended to serve as an introduction to users of X-ray fluorescence correction methods. For this reason, only selected mathematical models for correcting interelement effects are presented. The reader is referred to several texts for a more comprehensive treatment of the subject (2-7).1.1 This guide is an introduction to mathematical procedures for correction of interelement (matrix) effects in quantitative X-ray spectrometric analysis.1.1.1 The procedures described correct only for the interelement effect(s) arising from a homogeneous chemical composition of the specimen. Effects related to either particle size, or mineralogical or metallurgical phases in a specimen are not treated.1.1.2 These procedures apply to both wavelength and energy-dispersive X-ray spectrometry where the specimen is considered to be infinitely thick, flat, and homogeneous with respect to the depth of penetration of the exciting X rays (2-5).1.2 This document is not intended to be a comprehensive treatment of the many different techniques employed to compensate for interelement effects. Consult Refs () for descriptions of other commonly used techniques such as standard addition, internal standardization, etc.

A general description of the equipment is provided. Recommendations are made for preparing the instrument for measurements, establishing optimum temperature conditions and other criteria which should result in determining a useful calibration concentration range, and measuring and calculating the test solution analyte concentration.1.2 This standard does not purport to address all of the safety problems, if any, associated with its use.
