Abstract

The techniques employed for air analysis are much different from those used to analyze either the aqueous or the solid samples. The most important part of air analysis is what is known as “air sampling,” which involves techniques to trap or collect the organic or inorganic pollutants from the air. The volume of air sampled is very important to know to measure the final concentrations of the analytes in the air. Such measurements of volume of air, as well as the sampling techniques used, may be prone to error if not carried out properly. The instrumental analyses, however, are the same: GC, HPLC, or GC/MS may be used to identify and quantify the organic pollutants, atomic spectroscopy to determine the metals, and for the nuisance dusts and other particulate matters gravimetric methods may be adopted. Derivatization techniques may furthermore be applied, if such reactions are known, to convert the pollutants into their suitable derivatives for measurement. Portable instruments for in situ measurements of pollutants are not fully reliable.
