Okay, so for all you nay sayers and cocksuckers that gave me a hard time look at this PDF this is how all mass specs should be done better than any I have seen done yet period. I'm disappointed with the results at 25% but what can you do, Ohhhhh who wants to signup now?....
Here are the results explained!
See the attached Powerpoint slides. First I ran the LC-MS in reverse phase mode with positive detection. Mobile phase was water to acetonitrile (ACN) with 0.1% FA. Slide 2 shows that the peaks which elute during the gradient (30 min) are mainly associated with three peak clusters with maxima at 289, 433 and 865. From your information the peak at 289 is consistent with protonated testosterone. The other two are unknown compounds. They are not derived from the LC system, ACN or the mobile phase (see slide 3). Thus I extracted the chromatogram for each of the peaks at the said maxima and shown at the bottom (Slide 2) is the spectrum at ~ 19 min, consistent with testosterone and its Na adduct (m/z = 311). Slide 1 shows the same results for another sample preparated at 1in100 dilution in ACN. Basically the same testosterone peak is shown at 19 min. The more hydrophobic peaks for 433 and 866 are shown as spectra in the middle panel (Slide 1). The m/z= 866 might be a dimer of the m/z= 433 peak. Slide 3 shows a blank (ACN) injection. Slides 4 and 5 show the LC-MS/MS of the 1/100 sample tracking the fragmentation of the 289, 433 and 866 peaks. The 289 peak produces fragments with are consistent with the testosterone rings A and D (97 and 109) at 19 min. At 26.5 min the chromatographic peak (Slide 5) indicates that the 433 precursor is related to testosterone since it produces similar fragments plus a bit of the 289.4 precursor, presumably due to the loss of a side chain with mass of 144. The bottom MS/MS spectrum, also at 26.5 min (Slide 5) confirms that 866 is a dimer of 433. The Q1 spectra of the sample (not shown) shows that the charges of all the three peaks are +1. Based on the Q1(+) spectrum of the entire chromatogram (slide 2) and the fact that the intensities of 289 : 433 : 866 are in the ratio 1:2:1, it would appear that the ratios of the three compounds is 25%:50%:25% respectively. Thu testosterone is ~ 25% of the sample.
