Good day . i have another issue to my 8890. after replacing the fused silica in transfer line. tha air flow in FID is suddenly shutting down. then i try the detector diagnostic in the system it said test failed and need to replace the jet.
after replacing…
Hello,
this look like your plasma is not align with the cones. For the EM to failed it's difficult. You have to check for noise when it's doing it and if the counts are low when it's using mass 80. You can try to tune EM with mass 37 if you know where…
Try to ignite the plasma, without fixing the shield plate. Due to poor quality of argon gas or leak on gas line, reflected power will be above the limit and prevent the plasma sustain. Sometimes, the plasma sensor fiber optics tip is damaged, needs to…
Hello,
I am currently developing a residual solvent analysis method by Gas chromatography equipped with a flame ionization detector. My sample is an API with a phosphate salt attached. One of the residual solvents of interest is triethylamine. When…

Hello,
I have had a fair amount of success with posted questions in this forum, so here is another one. I am interested in knowing more about whether the flame ionization detector I have equipped on my HP/Agilent 6890 GC is the correct detector…
We have a lot of 1260s and 1290s in our lab, and as part of our sustainability initiatives are looking for ways to reduce our energy usage. Currently, all the instruments are left on (standby), and most of them also have the lamps on when not in use.…
When I need information about detectors I use the following books:
Raymond P. W. Scott "Chromatographic Detectors - Design, Function, and Operation", Chromatographic Science Series Volume 73, Marcel Dekker, New York (1996). ISBN 0-8247-9779-5.

Hi Guys,
I have a GC that does not seperate natural gas(maily C1 and C2 with small traces of C3+), it comes as almost one peak, and for condensate (C3+) it seperates C6+, and does not seperate C3÷C5,
I Have,
1: Readjusted the split ratio Many Many…
Hello Inês,
Typically we use the Performance report as a general health report of the instrument. Changing plasma parameters may cause the test to fail, unless you correct the limits. Moving the sample depth will decrease sensitivity and can increase…
Hello
I'm trying to setup report to have values in column "PASS/FAIL" green or red depends on result.
Can I do it as conditional formatting for column "PASS/FAIL" to mark FAIL as red based on text?
This column "PASS/FAIL" is custom field and…
