Improved Quantitative Selectivity of Clenbuterol in Human Urine using ,,, High Resolution on the TSQ Quantum Mass Spectrometer

Quantum Ionisation mode: Electrospray (ESI), positive ion SRM: Clenbuterol 277.1 > 203.0 +/- 0.3 Da, 22 V Collision energy Resolution: Experiment 1 0.7 Da FWHM on Q1 and Q3
Experiment 2 0.1 Da FWHM on Q1, 0.7 Da FWHM on Q3 Two separate quantitative analyses were performed at peak widths of 0.1 Da and 0.7 Da Full Width Half Maximum (FWHM) on Q1 in SRM mode. A peak width of 0.7 Da FWHM was used on Q3 for all analyses. Results The chromatogram of a pure standard of Clenbuterol in aqueous solvent demonstrates the retention time at 5.8 minutes (Figure 3). Figure 3: Determination of Clenbuterol retention time Experiment 1: Quantitative Analysis Performed at 0.7 Da FWHM The data below shows the quantitative analysis of Clenbuterol in Human urine at peak width settings of 0.7 Da FWHM on Q1 and Q3. Chromatograms are shown for blank urine (Figure 4) and urine containing Clenbuterol at 0.1 pg/L (Figure 5). Figure 4: Urine blank, 0.7 Da FWHM

Figure 5: Clenbuterol, 0.1 pg/L in urine, 0.7 Da FWHM Experiment 1: Quantitative Analysis Performed at 0.7 Da FWHM A calibration curve of Clenbuterol analysed at 0.7 Da FWHM was constructed using linear fit of peak area plotted against concentration, weighted 1/X (Figure 6). A cor
