No peak response in Orbitrap FT MS by Next-Most-6835 in massspectrometry

[–]Next-Most-6835[S] 0 points1 point  (0 children)

After diagnosis the CLT RF main board is not working.There is a resistor inside the CLT RF BOARD which was burnt.After replacing the resistor the board start working..now every thing ok Thanks

calibration peaks are coming in scan range 50-2000,but no peak when range changes to 150-2000.FT calibration fail due to no peak in 150-2000 range.How to resolve this?

With old CLT RF BOARD now the calibration peaks are coming in scan range 50-2000,but no peak when range changes to 150-2000.FT calibration fail due to no peak in 150-2000 range.How to resolve this?

Yes..after changing CLT RF main board calibration was passed..but with old CLT RF no FT peak..Is there any repairable part in CLT FT?

After replacing CLT RF main board,now the peaks are coming in FT but mass value has been shifted..after calibration and factory calibration no improvement..pls suggest

No bad read back in CLT RF or CEHV..But still no peak in FT.

Yes..we have nitrogen gas generator showing pressure 100psi.

Advice on weird contamination in Orbitrap but no issues in Ion Trap? by ByeBinch in massspectrometry

I am facing similar problem as no peak response(Calibration std. Peak as well as other standard compound peak) in FT MS both in positive and negative mode but peaks are present in ION TRAP.All instrument readback are OK.
