Thank you for the reply, I will have a go at it tomorrow. So essentially I just need to change one of my internal standard compounds to a normal compound, and use that as a single point calibration? It just seemed logical that every internal standard…
In an official Service Note we say "According to our lamp manufacturers there is no shelf life for LC detector deuterium (D2) lamps. Our logistic centers (LC) try to ship lamps from stock before they reach 12 months age. We see the lamps lasting for more…

What version of Windows do is it running? Go to the cell next to the logo (Type here to search) and enter winver and select the run app. At top it should say Windows 10, at this time only MassHunter 5.2 is Win11 compatible. 2 lines below Windows 10 will…
I have Open Lab CDS Chemstation Edition for GC systems and 7890A with FID. I get in vial concentration of an analyte in a sample from calibration curve as ppm. Need to generate an Intelligent report, I get concentration in sample (with Sample weight,…
I am using Agilent 8890. I am trying to set the standard for my GC-FID, I am injecting 5mL of methane gas standard with a gas-tight syringe through a switching valve which is set up to the left of my GC. However, I am getting different peaks and areas…
I have a MicroGC 990. Seemingly out of no where, the following error has popped up after hitting Control -> Single Run on a method we've been using for months:

Good Afternoon,
I'm developing a processing method using Mass Hunter Quant. 10.2 for ethanol (quantitate) and other related volatiles (ID only). The instrument setup is a single column that splits to two detectors FID and MS (FID for quant purposes…
Hi All,
I have an Agilent 7700 ICP-MS running MassHunter 4.6. Interesting issue - the instrument tunes just fine but when I go to run a sample, the data acquisition never stops; it continues well past the time it should have taken including rinse program…
Thank you very much for your quick attention. I take advice to use Labadvisor, however, the host computer is a windows 7 system and the built-in net framework is NE3.5, but LabAdvisor downloaded from Agilent site needs Net Framework version 4.7.2 , which…
