Hi everyone I have a strange issue to report. We are using a 6890GC with FID and TCD that was upgraded many years ago to give use LAN communication rather than GPIB. It works great even though it is over 20 years old. Just prior to Christmas we installed…
Hi,
1. It is not normal, that you have to purge the cell gas lines every time
2. Ou should perform at least following "Tests" during Plasma ignition: Torch Axis - EM - Resolution/Axis. But a performance report every day would be nice (and therefore…
Varian 710 oes, nebulization is ok, fog in the chamber is omogeneous, tubing, nebulizer, torch, cone cleaned and alligned.
Work fine till 2 weeks ago, after i've experienced this: fail to execute wavelenght calibration end torch allign, No response…
Hello Everyone,
I am using 7820A GC coupled with 5977B Mass Spec. After use I close the He tank and later on I get 2 messages - 'Front inlet flow shutdown' and 'Front inlet pressure shutdown'. I restarted the software but it fails to load any GC method…
I am building a report for some GC-FID data from a GC-MS/FID instrument. I have managed to build a report that contains the chromatogram and the table of peaks. I can scale the X-axis to the scale i need but I have been unable to scale the y-axis to show…
I am using OpenLab Chemstation C.01.10 on an 8890 with dual FIDs. I was trained on HP's version of Chemstation that reported both detector quant amounts in one row for precision purposes. It made it 10x easier to review data and confirm sample concentrations…
Hello, we are setting up a seahorse assay for a immunology master class. We want to measure the glycolytic rate in human PBMCs or purified human CD4 T cells activated vs non activated. We fail to see any difference. Has anyone done this kind of assay…
We have a Duo 2.5 foreline pump that was replaced in June of this year (2023). The previous Duo 2.5 installed had a sudden catastrophic leak, thus the replacement in June. The oil was filled up halfway and I set a marker with tape to monitor the level…
Hi Juliana
Yes, most likely the capacitors and/or the RF Tube. However, you can try to reduce the run power to 1.1Kw in the default ignition table. You may then be able to run for a few weeks with this reduced power level. You will need to reduce the…
Hi byoo,
Do you get any failed to communicate or any other message when you start up the software? You are correct if the busy light should be constantly flashing. This means you got a successfuk firmware load from the PC from ethernet connection. Can…
