| Research Abstract |
The purpose of the project is to develop application methods for identifying and quantitating various drugs and toxins using a Fourier transformation-linear ion trap mass spectrometer, shared in the Faculty. However, under the available LC conditions optimized to proteomic analysis, sufficient separation and reproducibility were not obtained. We thus purchased a quadrupole-time of flight mass spectrometer (Q-TOFMS); further experiments were rendered using this (liquid chromatography) LC-Q-TOFMS system.
Using the LC-Q-TOFMS system, amanitins in urine samples were sufficiently separated; the calibration curves showed good linearity in the range of 1 - 5,000 ng/ml. This system has enabled sensitive detection and identification of various synthetic cannabinoids and mifepristone, and their metabolites with high sensitivity. We are now constructing a screening system of 53 natural toxins. Hence, LC-Q-TOFMS will be a useful tool in analyzing various compounds in forensic toxicology.
