Pesticide Multiresidue Analysis of 303 Compounds Using Supercritical Fluid Extraction

[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...

[Validation study of a method for multiresidue analysis of pesticides in cereals and pulses using supercritical fluid extraction].

Supercritical fluid extraction (SFE) was applied to extraction of pesticides from cereals and pulses. Residues were extracted from homogenized samples mixed with water-absorbent polymer and supercritical carbon dioxide in a stainless steel tube, followed by elution with acetonitrile. Co-extractives were removed by means of mini-column clean-up. Measurement was performed by GC-MS/MS. Calibration...

Development of Environmental Analysis Methods Using Supercritical Fluid Extraction and Supercritical Fluid Chromatography

Supercritical fluid chromatography (SFC) was first attempted in 1962 [1]. Although several papers on SFC were published during the subsequent two decades [2], their content did not encourage many researchers to investigate this technique. After the introduction of fused-silica capillary SFC in the early 1980s [3], many papers describing fundamental studies as well as application studies appeare...

high pressures also requires special equipment. In summary, both RESS crystallization and SAS crystallization appear to be promising methods for generating supersaturation and therefore represent alternatives to conventional crystallization. Such alternatives may prove attractive in applications such as polymer and pharmaceutical processing, or in particle design for drug delivery. It is possib...
