5.1x00a0;Diffusive samplers provide a useful sampling option for studying time-weighted average indoor air concentrations of vapor-phase pollutants. They are easy and cost-effective to deploy enabling the collection of relatively large data sets. 5.2x00a0;The objective of this guide is to provide guidance for the placement and use of diffusive samplers that when uniformly applied enables the user to eliminate many potential interferences that may occur in diffusive sampling of indoor air. Since the analysis of the indoor environment by diffusive sampling is influenced by many factors other than the method of sampling, efforts are made to minimize interfering factors and maintain the air at conditions typical of the measurement location within the vicinity of the diffusive sampler. However, when performing certain diagnostic or special measurements, non-typical indoor air environmental conditions may be desirable or required. Thus, the objectives of a sampling study determine the conditions needed for sampling. 5.3x00a0;Diffusive sampling provides for time integrated measurements. Diffusive samplers are usually placed in an indoor environment over a time period to obtain a time weighted average concentration; hence, interfering factors potentially occurring over this period should be anticipated and eliminated where possible. Diffusive samplers often lack the sensitivity to measure short-term peak concentrations. 5.4x00a0;With suitable instruction regarding placement of diffusive samplers, placement, and retrieval of the samplers can be performed by unskilled personnel (for example, occupants). 1.1x00a0;This guide covers the placement and use of diffusive samplers in an indoor environment. 1.2x00a0;The primary use of diffusive samplers is to measure the exposure concentrations of specific gaseous air contaminants for occupants in a variety of indoor environments. 1.3x00a0;Diffusive samplers within this guide are used to measure concentrations of air contaminants in residences, public buildings, offices, and other non-industrial environments. A diffusive sampler is any air sampler that does not utilize electrical or mechanical power in order to supply air to the sorbent media or chemical reactant within the sampler and that samples according to Fickx2019;s first law of diffusion. 1.4x00a0;The purpose of this guide is to ensure uniformity of sampling within a variety of indoor environments and to facilitate comparison of results. 1.5x00a0;The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6x00a0;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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7x00a0;Th......

This Technical Specification specifies the long-term sampling of PCDDs, PCDFs and PCBs. There are three different sampling methods, which use the three different principles described in EN 1948-1 modified for long-term sampling requirements: - filter/condenser method; - dilution method; - cooled probe method. Each sampling method is illustrated in detail in Annex D. The sampling methods described in this document are designed for a sampling duration of typically four weeks. Additionally this document specifies a framework of quality control requirements for any long-term sampling method to be applied. With the methods described experiences were gained for a concentration range from typically 0,003 ng I-TEQ/m 3 up to 4,0 ng I-TEQ/m 3 and 0,003 ng WHO-TEQ/m 3 up to 4,0 ng WHO-TEQ/m 3 respectively at different stationary sources (e. g. waste incinerators, sinter plants, cement kilns). For the complete measurement method the use of EN 1948-2 and EN 1948-3 describing extraction and clean-up and identification and quantification, respectively, is necessary in order to determine PCDDs/PCDFs. Also EN 1948-4 is necessary for the analyses of dioxin-like PCBs.

This Technical Specification specifies procedures for the sampling, preparation and analysis of individual volatile organic compounds (VOCs) in waste gas, such as those arising from solvent using processes. Sampling occurs by adsorption on sorbents, preparation by solvent extraction or thermodesorption and analysis by gas chromatography. Examples of individual VOC are given in relevant industry sector BAT Reference documents (BREFs). The results obtained are expressed as the mass concentration (mg/m 3 ) of the individual gaseous organic compounds. This document is suitable for measuring individual VOCs whose ranges vary depending on compound and test method, refer to Annex B and C. This Technical Specification may be used to meet the monitoring requirements of the Industrial Emission Directive (IED) and associated supporting documents. This Technical Specification is not suitable for measuring total organic carbon (TOC). For the measurement of the mass concentration of total organic carbon then EN 12619 is applicable.

4. Significance and UseTop Bottom 4.1 The guide consolidates into one document, siting criteria and sampling strategies used routinely in various North American atmospheric deposition monitoring programs. 4.2 The guide leads the user through the steps of site selection, sampling frequency and sampling equipment selection, and presents quality assurance techniques and other considerations necessary to obtain a representative deposition sample for subsequent chemical analysis. 4.3 The guide extends Practice D1357 to include specific guidelines for sampling atmospheric deposition including acidic deposition. 1.1 This guide assists individuals or agencies in identifying suitable locations and choosing appropriate sampling strategies for monitoring atmospheric deposition at non-urban locations. It does not purport to discuss all aspects of designing atmospheric deposition monitoring networks. 1.2 The guide is suitable for use in obtaining estimates of the dominant inorganic constituents and trace metals found in acidic deposition. It addresses both wet and dry deposition and includes cloud water, fog and snow. 1.3 The guide is best used to determine estimates of atmospheric deposition in non-urban areas although many of the sampling methods presented can be applied to urban environments. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
