摘要:

AbstractImportant considerations are discussed for analytical SFE method development employing methanol–modified carbon dioxide and solid‐phase trapping. The focus of this study was to break the method development procedure into distinct steps so that the origins of low recoveries could be determined conclusively. Sulfonyl urea herbicides were used as probe analytes. Analyte solubility, analyte trapping, analyte trap removal (solid‐phase), and extract analysis were all shown to be equally important in achieving quantitative SFE recov
