Hi Marty,
Thank you very much for your answer. The "currentSignal.GetDoubleCC("TotalAreaAdj") does not give any value. Instead, I have used just " TotalAreaAdj" and it works. the final equation is "Peak_Area/TotalAreaAdj*100".
I really appreciate…
I am also interested in the question of compatibility of the existing power supply G 1946-80058/B with different models of the 6100 line: 6125, 6135, 6120, 6130? In general, there are more questions than answers and I’m afraid that without clear instructions…
This is normal as PONA columns are apolar phases with thin films. For your light HC's < C5 either a thick film (ca. 5 µm) or another phase/column would help, but higher HC's cannot be done then (see also Lance's answer). It's either switching or backflushing…
Are you running different methods in different worklists, or are the worklists all running the same method? I assume the same method across worklists, but this is not clear in your question.
Does this change in pressure lead to a change in your quality…
Hi Danielchsny, Yes power spikes from unscheduled power interruptions can cause damage to sensitive electronic circuits. Another contributing factor is that when power is lost to the LC/MS running under high vacuum the rough pump will stop, causing a…
Hi Carol, There is always a trade-off between Scan speed, mass resolution and sensitivity in any quadrupole mass filter. So if you decrease the resolution and keep scan speeds the same you will naturally get an increase in sensitivity. Based on the trouble…
What are the inlet and column configurations, flow rates, pressures, and timing setpoints? The fastest way to share that is to copy/paste the contents of the file acqmeth.txt that lives underneath your specific Our_Run_Method_Name.M subdirectory in Windows…
Yes - it was a bit of a mess - but I was able to fix it. Thanks for the heads up. Not everything could be fixed in the computer portion of the method. I had to go into the GC configuration and fix it there.
Thank you!
