Abstract
A field method is described for determining hydrogen fluoride vapour in air at concentrations up to 20 µg of hydrogen fluoride per litre. The gas is collected in an acidic solution of zirconium-Solochrome cyanine R reagent and the observed bleaching of the colour compared with standards. The apparatus used is simple to operate and the time required for a determination is less than 5 minutes. A dynamic method for the generation of standard atmospheres of hydrogen fluoride is also described.Keywords
