A 5% H2 blend should work also. If you're using multiple calibration standards, make sure the range of the standards matches or exceeds the expected range in your samples.
One thing to watch for: I have seen instances where H2 saturates the TCD at high…
Offsetting the axes, Y or X, is not a feature in MassHunter. You can do head to tail comparison.
Overlaying in different colors and choosing which one is active can be done but there's not a way to do what you're asking even in a custom report.…
Good morning. We analyze fatty acids and The compound response factor of each fatty acid before the softwere changed remained fixed now it changes. I tried to copy the various parameters set in the other gas chromatograph which has its own softwere, but…
Hello,
I'm having the same problem with the overwhelming amount of orange highlighting for samples where the qualifier peak was not found. I tried the suggestion above of enabling "Ignore Peaks Not Found" in the method and re-applying it to the batch…
The tune evaluation was written for an orthogonal ion source (SS/Inert/Extractor) system, atune or etune, running helium carrier gas between 0.8 and 1.4 ml/min, at 230° C ion source and 150° C quad temperatures. It may not pass using other temperatures…
Hello,
I am not sure which Agilent software (CDS 2.x , Chemstation, EZChrom) you are using, but most customers use third party software for simulated distillation and other RT vs BP petrochemical calculations. If your need is simpler, you could do…
