Standard Guide for Placement and Use of Diffusion Controlled Passive Monitors for Gaseous Pollutants in Indoor Air
SIGNIFICANCE AND USE
The objective of this guide is to provide guidance for the placement and use of passive monitors that when uniformly applied enables the user to eliminate many interferences in the sampling of indoor air. Since the analysis of the indoor environment by passive air monitors 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 passive air monitor. However, when performing diagnostic or special measurements, non-typical indoor air environment conditions may be desirable or required. Thus, the objectives of a sampling study may determine the conditions needed for sampling.
Passive sampling provides for time integrated measurements. Passive monitors are usually placed in an indoor environment over a time period to obtain a cumulative sample; hence, interfering factors should be anticipated and eliminated where possible. Passive monitors often lack the sensitivity to measure short-term peak concentrations.
With suitable instruction regarding placement of passive monitors, placement and retrieval of the monitors can be performed by unskilled personnel (for example, occupants).
SCOPE
1.1 This guide covers the placement and use of diffusion controlled monitors in the indoor atmosphere.
1.2 Diffusion controlled passive monitors within this guide include both area and personal monitors for use in residences, public buildings, offices, and other non-industrial workplaces and dwelling environments. A passive monitor is any air monitor that does not utilize electrical or mechanical power in order to supply air to the sorbent media or chemical reactant within the monitor and sample according to Fick's first law of diffusion.
1.3 The purpose of this guide is to ensure uniformity of sampling within a variety of indoor environments and to facilitate comparison of results.
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.

4. Summary of Guide
4.1 Contaminants in air are sampled by collection with a sorbent or chemically reactive medium in order to undergo subsequent
analysis for determination of concentration. Contaminants in air are transported to the sorption medium or reacting chemical
through vapor or gas diffusion. During the sampling process, the compounds, in a molecular state, diffuse from the environment
adjacent to the sampler through a first region of defined geometric structure and into a second adsorbing region containing the
sorbent.
