APPLICABILITY: This method can be used for simultaneous analysis of all analytes. High humidity greatly reduces sampler capacity and breakthrough volume.
INTERFERENCES: None identified.
OTHER METHODS: This method, NMAM 1450, Issue 3 is an updated analytical procedure [5]. This method originally combined and replaced the NMAM 2nd edition Methods S31, S32, S35, S37, S41, S44 through S48, and S51 [3]. Estimated LOD for each analyte is approximately 10 times lower than that of the previous methods.
