System Specifications    
MS/MS Sensitivity    
Electrospray Ionization (ESI)- A loop injection of 2 µL of a 1 pg/µL solution of reserpine (2 picograms, 3.28 picomoles total sample) at a flow of 400 µL/min of 50% isopropyl alcohol/50% water will produce a minimum signal-to-noise ratio of 100:1, for the transition of the isolated protonated molecular ion at m/z 609 to the largest two product ions, 397 and 448, when the mass spectrometer is operated at unit resolution in the full-scan MS/MS mode, scanning the product ion spectrum from m/z 165 – 615.    
    
Atmospheric Pressure Chemical

vacuum

My LCQ Fleet seems unable to go below 2E-5 Torr, and has stabilised around 2.15E-5.Anyone can point out what are the main causes of such failure?

thermo LCQ fleet_sensitivity issue..

I am unable to get sensitivity on the instrument, however Reserpine have shown the acceptable sensitivity for the system. Help!!
