متن کامل[Multiresidue analysis of pesticides in tea by supercritical fluid extraction (SFE) and GC-MS].
A multiresidue analysis of pesticides in tea using supercritical fluid extraction (SFE) and GC-MS was developed. The preprocessing using SFE shortened the total analysis time. The SFE extract contained less matrices than the extract obtained with organic solvents. However, these matrices disturbed instrumental analysis. So, the extract was cleaned up with ENVI™-Carb/NH2 and InertSep™ SI cartrid...
