A new method is described for the detection of drugs of abuse in urine, based on the techniques of lyophilization and liquid-solid extraction. Urine samples are acidified with acetic acid and then freeze-dried. The residues are then estracted and the extracts subjected to thin-layer chromatography

Due to recent advances in high throughput organic synthesis, discovery teams now need to profile increased numbers of analogs in vitro for their absorption, distribution, metabolism, and excretion (ADME) properties. Consequently, pharmaceutical companies are developing lower cost and higher throughp
The method for extracting Triton X-100 used by I. H. Mather and C. B. Tampling [Anal. B&hem. 93, 139-142 (1979)], has been extended to other detergents of dif%erent charge and chemical nature. All the detergents tested can be extracted with isopentanol in conditions in which not more than 8% of hydr
