ASTM E925-09(2014) 光谱缝宽不超过2 nm的可见紫外线分光光度计的校准监控的标准实施规程

4.1 This practice permits an analyst to compare the performance of an instrument to the manufacturer's supplied performance specifications and to verify its suitability for continued routine use. It also provides generation of calibration monitoring data on a periodic basis, forming a base from which any changes in the performance of the instrument will be evident. 1.1 This practice covers the parameters of spectrophotometric performance that are critical for testing the adequacy of instrumentation for most routine tests and methods2 within the wavelength range of 200 to 700 nm and the absorbance range of 0 to 2. The recommended tests provide a measurement of the important parameters controlling results in spectrophotometric methods, but it is specifically not to be inferred that all factors in instrument performance are measured. 1.2 This practice may be used as a significant test of the performance of instruments for which the spectral bandwidth does not exceed 2 nm and for which the manufacturer's specifications for wavelength and absorbance accuracy do not exceed the performance tolerances employed here. This practice employs an illustrative tolerance of ±18201;% relative for the error of the absorbance scale over the range of 0.2 to 2.0, and of ±1.0 nm for the error of the wavelength scale. A suggested maximum stray radiant power ratio of 4 × 10-4 yields lt;18201;% absorbance bias at an absorbance of 2. These tolerances are chosen to be compatible with many chemical applications while comfortably exceeding the uncertainty of the certified values for the reference materials and typical manufacturer's specifications for error in the wavelength and absorbance scales of the instrument under test. The user is encouraged to develop and use tolerance values more appropriate to the requirements of the end use application. This procedure is designed to verify quantitative performance on an ongoing basis and to compare one instrument's performance with that of other similar units. Refer to Practice E275 to extensively evaluate the performance of an instrument. 1.3 This practice should be performed on a periodic basis, the frequency of which depends on the physical environment within which the instrumentation is used. Thus, units handled roughly or used under adverse conditions (exposed to dust, chemical vapors, vibrations, or combinations thereof) should be tested more frequently than those not exposed to such conditions. This practice should also be performed after any significant repairs are made on a unit, such as those involving the optics, detector, or radiant energy source. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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.

ASTM E1866-97(2013) 分光光度计性能试验确定用标准指南

4.1 If ASTM Committee E13 has not specified an appropriate test procedure for a specific type of spectrophotometer, or if the sample specified by a Committee E13 procedure is incompatible with the intended spectrophotometer operation, then this guide can be used to develop practical performance tests. 4.1.1 For spectrophotometers which are equipped with permanent or semi-permanent sampling accessories, the test sample specified in a Committee E13 practice may not be compatible with the spectrophotometer configuration. For example, for FT-MIR instruments equipped with transmittance or IRS flow cells, tests based on polystyrene films are impractical. In such cases, these guidelines suggest means by which the recommended test procedures can be modified so as to be performed on a compatible test material. 4.1.2 For spectrophotometers used in process measurements, the choice of test materials may be limited due to process contamination and safety considerations. These guidelines suggest means of developing performance tests based on materials which are compatible with the intended use of the spectrophotometer. 4.2 Tests developed using these guidelines are intended to allow the user to compare the performance of a spectrophotometer on any given day with prior performance. The tests are intended to uncover malfunctions or other changes in instrument operation, but they are not designed to diagnose or quantitatively assess the malfunction or change. The tests are not intended for the comparison of spectrophotometers of different manufacture. 1.1 This guide covers basic procedures that can be used to develop spectrophotometer performance tests. The guide is intended to be applicable to spectrophotometers operating in the ultraviolet, visible, near-infrared and mid-infrared regions. 1.2 This guide is not intended as a replacement for specific practices such as Practices E275, E925, E932, E958, E1421, or E1683 that exist for measuring performance of specific types of spectrophotometers. Instead, this guide is intended to provide guidelines in how similar practices should be developed when specific practices do not exist for a particular spectrophotometer type, or when specific practices are not applicable due to sampling or safety concerns. This guide can be used to develop performance tests for on-line process spectrophotometers. 1.3 This guide describes univariate level zero and level one tests, and multivariate level A and level B tests which can be implemented to measure spectrophotometer performance. These tests are designed to be used as rapid, routine checks of spectrophotometer performance. They are designed to uncover malfunctions or other changes in instrument operation, but do not specifically diagnose or quantitatively assess the malfunction or change. ......

Standard Practice for Testing Flame Ionization Detectors Used in Gas or Supercritical Fluid Chromatography

ASTM E594-96(2006) 气相色谱法或超临界液相色谱法中使用的检验火焰电离探测器的标准操作规程

Although it is possible to observe and measure each of the several characteristics of a detector under different and unique conditions, it is the intent of this recommended practice that a complete set of detector specifications should be obtained at the same operating conditions, including geometry, flow rates, and temperatures. It should be noted that to specify a detectorrsquo;capability completely, its performance should be measured at several sets of conditions within the useful range of the detector. The terms and tests described in this recommended practice are sufficiently general so that they may be used at whatever conditions may be chosen for other reasons. The FID is generally only used with non-ionizable supercritical fluids as the mobile phase. Therefore, this standard does not include the use of modifiers in the supercritical fluid. Linearity and speed of response of the recording system or other data acquisition device used should be such that it does not distort or otherwise interfere with the performance of the detector. Effective recorder response, Refs. (5,6) in particular, should be sufficiently fast so that it can be neglected in sensitivity of measurements. If additional amplifiers are used between the detector and the final readout device, their characteristics should also first be established.1.1 This practice covers the testing of the performance of a flame ionization detector (FID) used as the detection component of a gas or supercritical fluid (SF) chromatographic system.1.2 This recommended practice is directly applicable to an FID that employs a hydrogen-air or hydrogen-oxygen flame burner and a dc biased electrode system.1.3 This recommended practice covers the performance of the detector itself, independently of the chromatographic column, the column-to-detector interface (if any), and other system components, in terms that the analyst can use to predict overall system performance when the detector is made part of a complete chromatographic system.1.4 For general gas chromatographic procedures, Practice E 260 should be followed except where specific changes are recommended herein for the use of an FID. For definitions of gas chromatography and its various terms see Recommended Practice E 355.1.5 For general information concerning the principles, construction, and operation of an FID, see Refs (1, 2, 3, 4).1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use.

ASTM E1303-95(2005) 液相色谱法用折射指数检测器规程

Although it is possible to observe and measure each of several characteristics of a detector under different and unique conditions, it is the intent of this practice that a complete set of detector test results should be obtained under the same operating conditions. It should also be noted that to specify completely a detectorrsquo;capability, its performance should be measured at several sets of conditions within the useful range of the detector. The objective of this practice is to test the detector under specified conditions and in a configuration without an LC column. This is a separation independent test. In certain circumstances it might also be necessary to test the detector in the separation mode with an LC column in the system, and the appropriate concerns are also mentioned. The terms and tests described in this practice are sufficiently general so that they may be adapted for use at whatever conditions may be chosen for other reasons.1.1 This practice covers tests used to evaluate the performance and to list certain descriptive specifications of a refractive index (RI) detector used as the detection component of a liquid chromatographic (LC) system.1.2 This practice is intended to describe the performance of the detector both independent of the chromatographic system (static conditions, without flowing solvent) and with flowing solvent (dynamic conditions).1.3 The values stated in SI units are to be regarded as the standard.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.

Practice for Refractive Index Detectors Used in Liquid Chromatography

ASTM E840-95(2000) 气相色谱中使用火焰光度检测器的标准实践

1.1 This practice is intended as a guide for the use of a flame photometric detector (FPD) as the detection component of a gas chromatographic system. 1.2 This practice is directly applicable to an FPD that employs a hydrogen-air flame burner, an optical filter for selective spectral viewing of light emitted by the flame, and a photomultiplier tube for measuring the intensity of light emitted. 1.3 This practice describes the most frequent use of the FPD which is as an element-specific detector for compounds containing sulfur (S) or phosphorus (P) atoms. However, nomenclature described in this practice are also applicable to uses of the FPD other than sulfur or phosphorus specific detection. 1.4 This practice is intended to describe the operation and performance of the FPD itself independently of the chromatographic column. However, the performance of the detector is described in terms which the analyst can use to predict overall system performance when the detector is coupled to the column and other chromatographic system components. 1.5 For general gas chromatographic procedures, Practice E260 should be followed except where specific changes are recommended herein for use of an FPD. 1.6 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.

Standard Practice for Using Flame Photometric Detectors in Gas Chromatography

ASTM E685-93(2005) 液相色谱法用固定波长光度探测装置试验的标准实施规程

Although it is possible to observe and measure each of the several characteristics of a detector under different and unique conditions, it is the intent of this practice that a complete set of detector specifications should be obtained under the same operating conditions. It should also be noted that to completely specify a detectorrsquo;capability, its performance should be measured at several sets of conditions within the useful range of the detector. The terms and tests described in this practice are sufficiently general that they may be used regardless of the ultimate operating parameters. Linearity and response time of the recorder or other readout device used should be such that they do not distort or otherwise interfere with the performance of the detector. This requires adjusting the gain, damping, and calibration in accordance with the manufacturerrsquo;directions. If additional electronic filters or amplifiers are used between the detector and the final readout device, their characteristics should also first be established.1.1 This practice is intended to serve as a guide for the testing of the performance of a photometric detector (PD) used as the detection component of a liquid-chromatographic (LC) system operating at one or more fixed wavelengths in the range 210 to 800 nm. Measurements are made at 254 nm, if possible, and are optional at other wavelengths.1.2 This practice is intended to describe the performance of the detector both independently of the chromatographic system (static conditions) and with flowing solvent (dynamic conditions).1.3 For general liquid chromatographic procedures, consult Refs (1-9).1.4 For general information concerning the principles, construction, operation, and evaluation of liquid-chromatography detectors, see Refs (10 and 11) in addition to the sections devoted to detectors in Refs (1-7).1.5 The values stated in SI units are to be regarded as standard.1.6 This standard does not purport to address all of the safety problems, if any, associated with its use.
