As the filament gets older and the source dirtier areas will go down. Just bump up the EM volts a little by say 24 and see what you get. Keep bumping it up until you get areas you want. It should not change the tune much. You can always set it back to…

We've been having issues with our LC-MS/MS 1260/6490 and 1290/6470 systems giving "LC Offline" errors when the instrument is all ready to go and we start a worklist. It clearly is connected, because it's showing the LC status the entire time. We're using…
From a GCMS perspective, 1.9 ml/min into the ion source is not optimal. The MS prefers down around 1.2 ml/min. Sensitivity is better and spectral tilt is more typical.
Septum head or septumless head? What is your gas supply pressure? When was the last…
Hello,
Question 1: Are you opening a snapshot or using review completed injections to open the in-progress injections? Is it possible you were on a replicate injection when trying to change the type.
Question 2: Andy is correct you must have the…
Helllo mighty Marty,
we have only one Infinity II device, so it can be useful. It works same as your example. But if we are going to compare this system with GC catalog it seems to be very painful to write all the info again and again when you are going…
Hello payninater ,
To utilize the inherited calibration curve you will need to copy the cal levels to the other targets. If you are doing this make certain your unknown targets have the same ISTD assigned. Quant does not verify this and simply applies…
Hello payninater ,
It is not possible to enter responses manually in the Method Editor.
As far as I know there should be no issue with setting your sample type and level in the batch table, creating a new method from acquired data, creating levels…
