Big grin

the multipole voltages were low enough to transport intact, unfragmented molecules of tryptamine hcl standard.

Is this spectra (peak 196.7 for example) properly calibrated? Still getting any of that mysterious MIPT signal? What was the mobile phase used for this sample?

Is the X-axis m/z? I am not familiar with those units, I am trying to compare with spectra found in online database

Uhmmmm.... Why are you still running on Windows XP, n00b?

when at last I saw walls far away to the right and left, but these long walls have
narrowed so quickly that I am in the last chamber already, and there in the corner
stands the trap that I must run into." "You only need to change your direction," said

yes, and none of the other signal. the mobile phase was 50:50 MeOH:H2O.
*edit* I found out what that signal really was: M + Na. tryptamine hcl with sodium adduct (common anomaly in LCMS).

m/z is mass/charge. in this case, the charge was +1. the compound is tryptamine hcl.

uhhhmmm, it's Windows 2000 Pro...and you're calling me a n00b..

the instrument is a 2001 model, MSRP $260,000 at the time. it'll still detect/identify nanograms of material. I'm not using the comp to play Starcraft, ffs.
