It is great you have such a nice experience with your results, however results accuracy is a matter of hardware robustness and method setting, not software. I your insist on this, I can recommend you to do the following steps:
1- get the licence number…
hello,I had the same problem as you to make the sum of impurities, I searched in the forum and I found the following formulas, to be verified because I am not an expert in formulas but it worked
ListImpND (Type string, scope signal) If (Count(CurrentSignal…
Hello Andy, thanks for your answer. It would be possible, however we would like to automate our analysis as much as possible. A manual calculation of the concentrations, depending on the initial weight, would make us go a step in the wrong direction.…
I was never able to do glycols via headspsce in the past. The only way I was able to do them was direct injection and FID. 5890 using megabore column. Maybe you could try SPME.
I made a new calibrant solution and did a full system tune. The system tune passed. However when I switched back to my low 1700 m/z range and did a mass cal/check tune my positive failed but my negative did not.
This is a 5977A that was built in mid-2015. How many runs on it? . High Energy Dynode (HED) related, Electron Multiplier (EM) related, signal related, or electronics related.
The first thing to try is to go into manual tune and turn OFF the HED. I'd…
I would check the pulse and analog HV values. If they reached ~ 1800V and 3300V accordingly, you will need to replace the EM detector. If EM tune fails but your calibration is fine, you can still measure. You just need to be sure that EM is replaced soon…
I am running GC 6890 (FID detector) alongside G1888 headspace.
I had noticed 4 of my later eluting peaks got increasingly worse in terms of shape and reproducibility. After running blanks (no injection and also blank vials), it seemed like the cause…
