I work in a laboratory on fruit and vegetable matrices. The laboratory is equipped with an LC-MS 2020 and PDA Shimadzu.
No, I've never tried this instrumentation brand and I'm trying to turn on the instrumentation (after 1 year of stop). I turned on the car yesterday and I left it to flux with the pre-set conditions and this morning I found the tank of the N2 empty (yesterday it was 180 bar).
The conditions are as follows
ESI interface
Temperature 350 ° C
DL temperature 280 ° C
Nebulizing gas 1.5 L / min
Thermal block 270 ° C
Drying gas 3 L / min
Pump:
Flow 0.2 ml / min
Zorbax column 2,1 x 5 150 mm, 0,1 diameter
I would like to know what you think of the operating conditions, if they are wrong ??
to premise that there are no losses, the cylinder is normal that ends after a day?
I do not understand why the mass detector does not "see" me anything since trying to do tuning stops at 99% "Initial Adjusting"
Thank you all! I hope in your help and answer
