Sampling and analytical methods for phosphine--a review.
An overview of sampling and analysis of phospine with an emphasis on industrial hygiene is presented. Recent advances in solid sorbents behavior allow these devices to be used followed by gas chromatographic analysis. Sampling with filter paper--AgNO3 and colorimetric analysis remains a reliable technique. A comparison of the strengths and weaknesses of analytical (gas chromatography, chromogenic, colorimetric and electrochemical) and sampling (impregnated papers, solid sorbents, bubblers and evacuated cylinder) techniques is made.
