Collection efficiency of solid surface and sorbent traps in supercritical fluid extraction with modified carbon dioxide

Publikováno v: Analytical Chemistry. 64:2352-2358

The effect of modifier on solid-phase trapping efficiency in off-line supercritical fluid extraction was studied. Two types of traps-solid surface (stainless steel) and sorbent (octadecyl silica)-were studied with pure carbon diocide and 1%, 2%, 4% a

Publikováno v: Journal of High Resolution Chromatography. 13:393-396

Sub- and Supercritical Fluid Chromatography (SFC) were used to separate seven purine and pyrimidine-based drugs. A two-pump system was used, where one pump delivered the carbon dioxide, and the other pump delivered modifier. The modifiers used in thi

Supercritical fluid extraction of active components in a drug formulation

Autor: L. T. Taylor, L. J. Mulcahey

Publikováno v: Analytical chemistry. 64(9)

Sulfamethoxazole and trimethoprim have been extracted from a drug formulation, Septra Infusion, with pure supercritical carbon dioxide. Both direct extraction of the aqueous-based matrix and indirect extraction of the formulation immobilized onto Cel

Collection efficiency of various solid-phase traps for off-line supercritical fluid extraction

Autor: L. J. Mulcahey, J. L. Hedrick, Larry T. Taylor

Publikováno v: Analytical chemistry. 63(20)

Solid-phase extraction tubes were evaluated as traps for off-line supercritical fluid extraction. Normal- and reversed-phase traps were studied with hydrocarbons, phenols, and a "test mixture" in order to determine the trapping efficiency. These trap
