Abstract

In this study, the QA/QC test for the combined application of DNPH cartridge – HPLC/UV method wasinvestigated in the collection and analysis of formaldehyde in air using three types of DNPH cartridgesamplers made by three independent manufacturers. For these experiments, gaseous standards offormaldehyde (FA) were prepared at 7 concentration levels that fell in the range of 44.1~3400 nmol/mol.According to our analysis, the levels of cartridge blank (0.13 ~ 0.26 ng) are found to be fairly high to requireroutine check up for each experiment. The recovery patterns of FA were highly comparable betweendifferent cartridge products, when standard gases are supplied in the concentration range up to 177nmol/mol. All 3 types of DNPH cartridge exhibited highly similar recovery rates at concentrations below 1.7㎛ol/mol, while the maximum recovery was attained from the product B. The overall results of our studysuggest that one should calibrate the samples in the optimal range of recovery with routine check up ofblank values.
