Hello
I need to do an LC/MSMS method for quantification on a compound that doesn't ionize into [M+H]+ (barely observed) but only into [M-H2O+H]+
Is there a problem with doing MS/MS on a [M-H2O+H]+ parent ion ?
(PS: negative ionization is not an…
Hi again Raina,
as I already told you this cannot be done with just one column, especially with the CO2 concentration up to 20% and water included and the necessity to analyze H2. This is an application we normally build an analyzer for. You need at…

Operating like this puts sub-optimal flow into the GCMS ion source of more than 2 ml/min. Please make sure that you have a system with a turbomolecular high vacuum pump and not a diffusion pump as 2 ml/min exceeds the maximum allowable flow into a diffusion…

Hi Margot,
It may well be that the column performance has deteriorated so much within the 7 months that the EasiVial standards are measured with poorer PDI values. The column performance can be tested with regular plate count determinations. It is a…
Hi sojeong,
every test report, delivered with aour columns, contains multiple specifications, but they are all measured with specialized systems and software. That means you might not be able to reproduce them identically. BTW for plate count you also…
Hi, I cannot configure the column compartment (CC) as it came integrated with the vial sampler on LC1290. We have the G7129B model for the integrated vial sampler and CC. I tried adding the column compartment details from the instrument configuration…
When the tuning is done at 3200 (+) everything is fine. When I change it to tune at 1700 (+) the masses are reasonably accurate. After it gets to the third mass (620) it appears that the entire spectrum shifts by about 1.5 AMU and the tuning fails. There…
