Hello,
To calculate the RSD and Pass/Fail results, one can try the following:
In the reporting go to the edtor and open "table properties"
In my specific case, I want to calculate RSD for Area, so I choose the column A, pA*s and press "Column…
Hi everyone, My MP-AES 4210 Machine sa is failing to suck/take-up the samples from the sample tubes..
I tried changing the sample pipes but nothing worked. Kindly asking for help on how to sort out this problem?
Regards,

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.
Since the FID and TCD are in series, I would guess that the extra noise on the peak through the FID is due to the TCD valve switching between carrier and reference. Try setting the FID signal rate to 5 Hz. Also, the FID makeup flow can be reduced or turned…
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…
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…
hi all,
we have ICP-MS 7800 and getting error 1445. The content of the error is as follows:
"1445, Error: Plasma gas flow rate is too low." We can't ignite plasma.
Gas valves and gas line have been checked and there is no problem.
Does anyone…
Dear Colleagues,
I have GC-FID 8890 and i'm using Gas saver feature but I'm observing when I change time of gas saver , the retention time is changed.
for instance, I set gas saver at 20 ml/min after 2 min then inject methanol and the RT is 4.74 but…
