New Obesity Data Have Been Reported by Investigators at Academy of Forensic Science (Analysis of 15 Anti-obesity Drugs In Urine Using Thermal-assisted Paper Spray Mass Spectrometry).

Furthermore, the thermal-assisted PS-MS method exhibited good linearities (R-2, 0.9903-0.9997) within the range from 10-100 to 1000 ng mL(-1) for the direct quantitation of anti-obesity drugs in urine samples with an internal standard." By incorporating a heat source and optimizing the spray solvent and paper substrate, this technique demonstrates reduced matrix effect and higher sensitivity compared to traditional PS-MS methodology for direct analysis of anti-obesity drugs in urine samples.
