It is proposed that lee scientific investigates and developsnew and improved instrumental methods for the analysis of n non-volatile organic compounds in complex environmental ma matrices by capillary column supercritical fluid chromato graphy (sfc). non-volatile compounds of specific interest… More

Analytical methods for detecting pesticides, antiboiotics, and metabolic products in meat products are tedious and time-consuming. this study will evaluate supercritical fluid extraction and chromatographic techniques for analysis of these compounds which may be polar, thermally unstable, or… More

The detection and characterization of pesticides, industrial solvents, and their metabolites in body fluids and tissues are important for evaluating the potential long-term health effects of the exposed population. unfortunately, analytical methods presently available are generally tedious,… More

The analysis of cannabinoids for research or screening for cannabis abuse requires methods capable of characterizing and quantifying metabolites of the cannabinoids which are generally polar or thermally unstable and which must be separated from a complex biological matrix. supercritical fluid… More

Gas and liquid chromatographs are the most routinely used instruments in analytical and clinical laboratories for the analysis of organic compounds. the objective of lee scientific, inc. is to manufacture an instrument that uses supercritical fluids instead of gases or liquids as mobile phases. the… More

Capillary separation techniques place stringent requirementson chromatographic detection systems. detectors for separation techniques, such as capillary liquid chromatography, capillary supercritical fluid chromatography, and capillary zone electrophoresis, are required to measure minute amounts of… More
