Drinking water is a significant source of environmental exposure, especially for small children. Countries around the world have put regulations in place to monitor drinking water quality for a wide range of hazardous compounds. Methods such as SL 392-2007 in China, the EN methods in Europe and US methods such as method 525.2 cover a large suite of analytes of concern. They can be effectively extracted using solid phase extraction (SPE) disks and using GC/MS for detection.

US EPA method 525.2 may use solid phase extraction (SPE) to extract the analytes of interest from water samples. It includes a variety of quality control measures to ensure the method is under control throughout the analysis. The Biotage® Horizon 5000 was used in this study to extract the EPA Method 525.2 analytes from six prepared water samples. The Atlantic high-capacity C18 disks provided excellent recovery of the large suite of compounds extracted in water. The Biotage® Horizon 5000 system provided uniform performance and a hands-off approach to the extraction step. The reproducibility of the six runs was excellent and the average of the standard deviation values was 2.57%.

Immunosuppressants inhibit or prevent the activity of the immune system used to prevent rejection of transplanted organs and treat autoimmune diseases. Due to the risks of immunodeficiency, those under treatment must undergo constant therapeutic drug monitoring (TDM) requiring reliable and robust analytical techniques for quantification of these drugs. Current methodologies use immunoassay techniques to measure immunosuppressant levels in patients which are expensive, time consuming and susceptible to issues with cross reactivity. The sample prep method in this application note offers an alternative approach to immunosuppressant analysis with LC-MS/MS giving more reliable and robust recoveries with no cross-reactivity and cost saving opportunities. Analyte recoveries range from 60-97% with RSDs all below 10%.
