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…
