this is in the mass spec thread as well...
Ok, i've got a few minutes, so let me explain the spectra. First off, you do not figure in "displacement" of the test in the oil, sorry
@MANWHORE. The compound dissolves in the oil, the volume delta is assumed to be zero for practical purposes. it is not zero, but it is negligible.
for the test e sample: 10microliters is dissolved into a know amount of chloroform (1.5 ml), and the sample in chloroform is injected into the mass spec. the mass spec has a very short column on the front end ("Waters") prior to the ionization chamber. that short column crudely separates the contents of the sample. bb, ba and oil blow through, and compound is shown as a peak or peaks. thus, in the spectrum you see one of more peaks, those are the "stuff" in the oil, the powder, whatever it is. the "stuff" is ionized, accelerted through the instrument field, and are detected as ions impacting the detector. molcular weight in "TOF" (time of flight) is determined by how long it takes the charged compound to travel the length of the ion trap.
if you look at the spectra, there are two numbers, one is "TIC" or total ion count. that is all the "stuff" that hit the detector. for the Benzyl alcohol, benzyl benzoate, oil chloroform you "tell" the instrument basically not to look for low molecular weight crap like that (not scan less than a certain mw). the sample contains 202 mg of "stuff" based on total ion count.
there are two peaks in the first spectrum, those peaks are the "stuff" one peak is test e, the other is whatever else is in the sample.
