An enhanced procedure for measuring organic acids and methyl esters in PM2.5 [PDF]
Atmospheric Measurement Techniques, 2015 A solid-phase extraction (SPE) pretreatment procedure allowing organic acids to be separated from methyl esters in fine aerosol has been developed. The procedure first separates the organic acids from fatty acid methyl esters (FAMEs) and other nonacid ...
