The development of a sampling and analytical method for the determination of monochloroacetic-acid (79118) (MCA) in air was described. The method was based on the collection of the compound from air using silica-gel as the solid sorbent. The compound was desorbed with distilled, deionized water. Ion chromatography with electrolytic conductivity detection was used for the analysis. MCA was detectable in 3 liter air samples in the concentration range of temperature of the test gas was 27 degrees-C and the relative humidity was greater than 80 percent. At each concentration level tested, each of six prototype silica-gel tubes was simultaneously exposed to about 3 liters of the test atmosphere at a nominal sampling rate of 0.2 liters/minute. The average recovery of MCA ranged from 94 to 100 percent. The bias of the method with respect to the independent method was small, the average bias being less than 2 percent over the range of the method, 0.350 to 28.9mg/m3.
