A method is described for the separation and collection of gaseous atmospheric forms of fluoride reactive with sodium bicarbonate and particulate forms of fluoride which are collected by filter. The particulate matter is collected on a membrane filter, and the gaseous fluorides are removed by reaction with sodium bicarbonate coated on the inside wall of a borosilicate glass tube. The fluoride collected by the tube is eluted with water or buffer and analyzed for fluoride, and the particles collected by the filter are eluted with acid and analyzed for fluoride. (BLM)
