Hello Community
We have a reproducabiility problem on GC-FID's. We run an alkane standard every day in the morning. Peak shapes are looks good but when i compare the total area of the peaks over the last weeks an month, its very bad, i have a standard…
Thanks Marty, I was afraid of that.
Too bad really since piecewise is the most conventional kind of multi-level calibration.
I train using the example of a typical pH meter where they still naturally calibrate at pH 4, 7, & 10. Therefore there…
Hi
How do I remove FID signal from the report for a dual TCD & FID GC, we use just TCD detector to analyses gas samples and this issue appear yesterday.

You can swap out cylinders to do it, but that means a lot more tubing, etc. to purge when you want to run. With the EPC unit, you would simply load the appropriate method to use it and the switch is done at the instrument. Much less tubing to purge and…
Hi Agilent,
Due to helium shortage, we need to change carrier gas for our GC-FID. Most documentation for Agilent suggests either H2 or N2, and the Chemstation configuration shows those options as well.
We are considering using argon, however, I…
This problem occurred after updating Openlab CDS Software 2.2 Version to 2.4 Version. GC# 7890B With FID , and TCD Detectors With OpenLab CDS Software 2.4 After installing the software version 2.4 and after a gas sample injection I noticed that there…
There's a lot going on. You have Column 1 in Constant Flow to a PSD in Constant Pressure with PSD Purge at 0 ml/min. Is there a purged splitter plate installed or a Purged Ultimate Union? The flow into the MS changes throughout the run due to the PSD…
Carbon disulfide is another option for wash solvent when running naphtha or crude oil samples. It's response on FID is low compared to hydrocarbons, so there should be little to no response if some residual is in the syringe.
