The ability to extract a broad range of different drugs from a biological matrix allows for the expedited analysis of a patient sample using LC-MS/MS. Typically small molecules are extracted from matrices like urine based on their polarities. A fast and reliable sample preparation method that could be implemented to extract drugs of different polarities from urine could be used as a screening tool to quickly identify the presence of illicit drugs in patient samples using LC-MS-MS.
This poster demonstrates the utility of supported liquid extraction for the extraction of over 30 different acidic, basic and neutral drugs in urine prior to LC-MS/MS.
