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…
