Title Laboratory and field validation of the GC-NPD method for the measurement of formaldehyde in the workplace
Bibliographic information Apr. 2005, Vol.2, No.4, p.244-250. Illus. 23 ref.
Abstract The aim of this study was to develop a new analytical method for measuring airborne formaldehyde concentrations in workplaces and to evaluate the performance of the method through laboratory and field tests. The method involves adsorption on a sampling tube containing a coated silica gel, followed by gas chromatography on a chromatograph equipped with a nitrogen-phosphorus detector (GC-NPD). In laboratory tests, the GC-NPD method was as sensitive as the NIOSH analytical method, which uses high-performance liquid chromatography equipped with ultraviolet detector. The analytical precision and 95% confidence limit of the estimated error for the GC-NPD method satisfied the OSHA sampling and analytical criteria. In field tests, the overall uncertainty of the GC-NPD method satisfied the NIOSH criteria for sampling and analytical methods.
