Hello, How often does your reference amount for the compounds change? If it never changes or changes on an infrequent basis I would suggest using a constants file in custom calculator. Also we have seen syntax issues with expressions in IR when using…
Have you checked that your stock standards are not contaminated and tried a second source of SIC. Do you run He in addition to nogas and does it only fail for nogas but pass in He?
I've also seen Sb stick around in the tubing, autosampler probe, and…
I have the headspace autosampler 7697A attached to a GC 7890A. I have two issues. the first is a growling noise when the gripper moves in the downward motion. Not the entire way just the middle third. I am guessing a service call will need to be made…

Agilent 1200 Series Analytical Fraction Collectors_ Continues to FAIL initialization, also error code 3833 and error message needle too long, too short or missing. please Advise
Hi Everyone, I am hoping I could get some advice with separating Aniline and DMSO with GC-FID.
We tried DB-Wax, DB-624, DB-5 so far but it did not work well. The retention time could be 2 min different max but the problem is DMSO has some impurities…
Hello,
That will work but what value are you displaying? If you want the logic to be if any injection fail it shows unmet then you would need to store and evaluate the logic. I would have a hidden column that converts met and unmet to 0 and 1. You…

Hi All,
I was trying to perform the Sampler Leak Test on the G7167B 1290 Multisampler. Whenever it reaches the last portion of the leak test (Blindseat leak measurement) the pressure just could not build up and the whole Sampler leak test will fail…
