Title Laboratory evaluation of a novel reactive passive sampler for the quantitative determination of formaldehyde in air
Bibliographic information Nov. 1994, Vol.55, No.11, p.1061-1068. Illus. 14 ref.
Abstract A colour-indicating passive dosimeter for formaldehyde, the AirChem Technologies (ACT) Monitoring Card System, was developed and evaluated. Test atmospheres of formaldehyde were generated by the injection of formalin into a heated stream of nitrogen, with subsequent dilution with charcoal-filtered air to produce concentrations in the range 0.1 to 2ppm. The mixed gas stream was introduced into an insulated cylindrical test chamber equipped with a rotating disc sampler holder. The ACT card readings were highly correlated with results obtained with NIOSH Method 3500. Results of accuracy and precision tests are discussed.
