Comparative sampling of hydrogen fluoride with passive and active samplers.
The paper presents a review of passive methods for sampling of hydrogen fluoride. The applicability of these methods for both evaluation of worker personal exposure and area monitoring is discussed. Two passive samplers were used: AREA/EPA and IMROH. The aim was to evaluate the efficacy of passive samplers in comparison with the current NIOSH analytical procedure for determining ambient levels of hydrogen fluoride involving sample collection in a bubbler or an impinger with 0.1 M sodium hydroxide. The sampling rates of the samplers were derived from Fick's First Law of Diffusion. The samples were analysed quickly and easily with a fluoride ion-selective electrode. The results of the tests indicated that the AREAL/EPA sampler design is better suited for measuring worker personal exposure and gives better correlation with the reference method (r2 = 0.66554).
