Use 1 meter of deactivated fused silica tubing going into the source (the same diameter of your column), then use a union (either the press-fit glass type of, better yet, the SilTite brand) to connect to your column in the oven. When you want to change…
Hello tdnola , "in use by another..." is a safety function that prevents a second session to the MSD: OK & wanted function. 1st) troubleshooting because a PING does only a small (OSI) communication check (are voltages & cabling OK?), I recommend the communication…
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…
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…
Were you able to join us on April 11th for our Agilent GC Live session? If so, we would like to hear your thoughts and questions. If you missed it, please see the video below.

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…
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…
