Thank you for your reply. I have not worked much with Gas GCs and I am not that familiar with different parts of it. I have performed leak check around front inlet and inside oven compartments (around columns). There was no leak. Could you please show…
The May 2011 issue of Dissolution Technologies ( https://dissolutiontech.com/DTresour/BackIssuefldr/BackIssuesfrmst.html ) compiles a lot of the thoughts of various agencies regarding the use of the alternate MQ procedure. MQ does have acceptance in most…
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…
Hi xiangui 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…
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_Ultivo , There is always a trade-off or balance to be struck 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…
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!
