A METHOD FOR THE DETERMINATION OF STRONG-ACID VAPORS IN THE PPM RANGE

Abstract

A nondiscriminating method for the quantitative detection of strong-acid vapors has been developed. The colors produced by passing known volumes of suspect air through disks of filter paper impregnated with an acid-sensitive reagent are compared with the colors on a calibrated reference chart. Reproducible sampling and analysis are accomplished in less than one minute with one to five strokes (100-500 cc) of a bellows-type hand pump. The range of the method as presently calibrated is 0.2 to 40.0 ppm by volume as monobasic gas.
