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...

Supercritical Fluid Chromatography

Since there is an enormous volume of information on the separation of antibiotics in the literature, readers should be able to Rnd HPLC conditions for almost any antibiotic of interest. Readers are also encouraged to consult the ofRcial compendia for analysis of bulk or formulated drugs. For analysis of biological samples, the samples may be directly injected with a column switching technique i...
