Hi Norbert Thank you for your quick response. As you said we are using a GC Agilent 7890 with a Agilent headspace. We have an issue with the RSD. The first 5 injections are really good but after inject a sample the next STD injection to close the run…
You can program a gradient to go to 100%B in theory. The BPR control will not be great at 100% co-solvent but its possible. However, I have not seen an application which requires more than 50% MeOH, EtOH or IPA co-solvent. Maybe others on here have specific…
"No Emission Current" -- This message just says that the filament is not working.
Wait long enough after pumping down. Don’t turn on the MS to just ‘take a look’ to see how the pump down is going. The residual oxygen damages the filament immediately…
Hello I am using Chemstation version B.04 and I recently found the mentioned macro. However, it does not seem to properly work. First, it failed at the Revision, therefore I took a look at macro file and found out supported versions were only previous…
Hi, Thank you for your replies. We had some assistance by email from Agilent and we checked several points. We changed the EM horn and cleaned the HED. The clip that holds EM horn seemed to be fine. We also ran several tests from the Lab device toolkit…
Martin, I have run into one more problem. In order to display the compound as a percentage, I also need to get the average of another field, but this one is a custom field( "Sample Weight/g") . I tried using the same query that you created to get the…
Hello, I updated the tags on this post to increase visibility. The first thing I would recommend would be to run the Software Verification Tool (might be called the Installation Qualification Tool or IQT in your revision) found by going to Start>All Programs…
Hello, If you want to approach this from an intelligent report angle, then you can set up a Pass/Fail flag on a Sequence Summary Report using the IIf() function. The tricky part would be to make sure that the logic in the Pass/Fail expression is referencing…
Hi Kristen, Thanks for the speedy reply and links, really useful. Everything parts wise appear OK. The ALS syringe (5ul gold syringe barrel ( 5182 0836) with 0.32um 26-32/42 cone needle (5182-0831)) is listed under 7673/7683 On Column autosampler syringes…
Hey guys, Our gradient test has been failing, got a new MCGV, replaced inlet and outlet filters, rotor seals, frits, switched degassers, switched lamp, cleaned flow cell, and still get a lot of drift...particularly when more than one channel is used.…
