• Description:
  This chapter discussed two types of measurement methods for gases and vapors. The first type included methods which remove the material of interest from air, retaining it for subsequent analysis. The second type determined the analyte directly in the atmosphere, more of a monitoring approach. Changes have been made in the area of measurement over the years with many of the methods which had been originally developed for air pollution research and control being modified to measure personal exposure and instruments first attached to the bench in the laboratory becoming miniaturized for use in the workplace environment. Several gas and vapor monitoring instruments and methods were discussed including ultraviolet and visible spectrophotometry, infrared analyzers, chemiluminescence, combustion, electrical conductivity, electrochemical analyzers, coulometry, flame ionization, gas chromatographs, photoionization, and metal oxide semiconductors. A growing concern in this field has been the measurement of exposures which would simultaneously characterize the physiological significance of the identified exposure. The physiological significance may be evaluated by measuring a property such as reactivity with a specific substrate or by using a sampling device which emulates a biological system.
