Hi hennindm, Congrats on your 8890 purchase! The new GCs are designed to be used both in local settings with a computer near the instrument, and remotely, so the best fit was to build the data access into a workflow that permitted both, aka the browser…
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…
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, 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…
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.…
Hey guys, I'm calibrating a UV/Vis, instrument model 8453, and I seem to consistently give varying results for the photometric accuracy test (with potassium dichromate). The protocol requires it be done under 4 minutes. My question is, why? Is it unstable…
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…
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…
Hello, I recently replaced a SmartCard in my 7700x and have not been able to communicate with the mass spec via MH. The IP settings appear to be correct for the peer to peer connection (192.168.1.127 PC ; 192.168.1.128 7700x ; 255.255.255.0 subnet masks…
