Instability in the anode voltage will cause baseline problems in your detector signal. For example, if the lamp doesn't light properly, the voltage will reset and you will see periodic changes in the baseline. I have seen old lamps sometimes produce odd…
I can't seem to get our new instrument to pass an EPA DFTPP tune for method 525.2. We recently got an instrument with the hydroinert source and I have only gotten a couple of passing tunes but nothing that is repeatable. I have tried manual tuning myself…
Yes! I checked the line too as according to the instructions (+) How to Disassemble and Assemble the HES (High Efficiency Source) - Articles - GC/MS Portal - Agilent Community
I will take a picture when I have them out next time. Thank you so much for…

Hello APacana ,
The reason for the difference in response between the TIC and the EIC is because when you extract the TIC of a given precursor you are extracting the ion signal from all precursors that create a 72 product ion, using your example. If…

At 1 mL/min pumping water, the pressures are as follows:
Pump + Column = 53 bar
Pump + Column + 0.1 mm ID 30 cm tubing = 70 bar
Pump + Column + Tubing + Flow Cell = 75 bar
I have also confirmed that this pressure fluctuation has nothing to do…
It all depends on your following steps. You can even use Methanol or Acetonitrile for the protein precipition: Protein Precipitation for Biological Fluid Samples Using Captiva EMR-Lipid
