Hi I'm using chemstation revision G1701EA E.02.02.1431 and the last successful launch was a day yesterday. It seems the malfunction accrued (during a "run" with a "new" method we are trying. involves FID HS for DCM residue, all the vials were sampled…
The Agilent Equipment Qualification Plan (EQP) for OQ is freely available on the Agilent website for potential customers to review. I have attached the standard EQP OQ for GC
Hello everyone,
I have created a simultaneous SIM/scan method and we're using a HS-SPME-GC-MS system (GC: Agilent 7890 A GC-System; MS: Agilent 5975C Inert XL MSD with Triple-Axis Detector; Software: Chemstation G1701EA E.02.00.493).
We get a TIC…
Hi community,
maybe someone has an idea what I could do, before a technician comes over.
During my absence my colleagues told me that our HPLC (1260 Vialsampler, 1260 Inf II Flex pump, TCC, FC-AS, DAD) does show a peak shift of about 3 to 10 minutes…

We work with a Q-TOF 6545 and it fails positive auto tune. Is there anyone who knows this error, what causes it and what can be done to rectify this? Thank you
Hello, I am trying to generate a streamlined intelligent report in OpenLab where we can capture all peaks of our SEC gel filtration standard in a single table and be able to evaluate APD Pass/Fail for each peak and Resolution between BGG and Ovalbumin…
Thanks for the feedback. I have re-optimized the lamp alignment, but I didn’t get much (if any) improvement. I also made some adjustments to the sample position, which I think helped a little. I think some users have been fiddling with the sample position…
Yes, it is the constant flow mode. The following is the method I am using: Carrier gas: Helium Carrier gas flow rate: 1 mL/min (constant flow) Injection volume: 1 μL Injection port temperature: 250 °C Split injection ratio: 30:1 Initial oven temperature…
