Perspective on application of supercritical fluid extraction to pesticide residue analysis

Supercritical fluid chromatography - Application to trace analysis

Figure 3. High performance capillary SDS-PAGE separation of myoglobin and several of its fragments. Conditions: 400 V/cm, 34 AA, 25 'C, migration distance 20 cm; fused-silica capillaries; 75 Am ID, T-12.5%, c=3.3%. Buffer: 0.1 M Tris-HPO0 (pH=6.9), 0.1% SDS, 8 M urea. Supercritical fluid chromatography (SEC) is fast becoming the method of choice for many separations involving nonvolatile, react...

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...

Pesticide residues in canned foods, fruits, and vegetables: the application of Supercritical Fluid Extraction and chromatographic techniques in the analysis.

Multiple pesticide residues have been observed in some samples of canned foods, frozen vegetables, and fruit jam, which put the health of the consumers at risk of adverse effects. It is quite apparent that such a state of affairs calls for the need of more accurate, cost-effective, and rapid analytical techniques capable of detecting the minimum concentrations of the multiple pesticide residues...
