Slide Presentation
• The method is capable of easy confirmatory and quantitative analysis of 46 illicit drugs at LOQs of 0.5 – 5 ng/mL in urine. • Ultrahigh mass resolution of 50,000 FWHM provided the necessary selectivity to identify 46 drugs in urine in 9 minutes with minimal sample preparation • Analyte confirmation is achieved by utilizing better than 5 ppm mass accuracy with external mass calibration. • Good quantitative accuracy achieved by isotopically-labeled standard. • Nicotine example demonstrates the need for ≥50,000 resolution in addition to exact masses.
