Measurements have been conducted to examine the performance of formaldehyde, acetaldehyde, and acetone using silica and C{sub 18} cartridges coated with 2,4-dinitrophenylhydrazine. Laboratory measurements for formaldehyde were conducted using a paraformaldehyde generator to produce reproducible and constant concentrations of the compound. For acetaldehyde and acetone, known concentrations were generated in Teflon chambers. The compounds were routed into a sampling manifold where simultaneous measurements could be made with multiple cartridges. Typical concentrations employed in the study were as follows. HCHO: 0.5--25 ppbv; CH{sub 3}CHO; 0.5--10 ppbv; CH{sub 3}C(O)CH{sub 3}: 0.5--10 ppbv. Additional measurements were conducted for these compounds in the presence of potentially interfering compounds such as ozone and water vapor. Serial cartridge collections were periodically used to investigate breakthrough of the carbonyl compounds.
