Hello,   I am missing the snapshot function, from the old Chemstation.   Is there a way, to get any information about the currently running sample out of the system ?   Or do I have to wait, till the sequence is finished.     Thank you.

I'm writing an assignment on fatty acids in Chia seed oil, and to that i'm using GC But when i try to identify the 5 components (C16:0, C18:0, C18:1, C18:2, C18:3) it keeps showing an extra peak that shouldn't be there. I tried to make a standard solution with only C16:0 in order to identify it, but the extra peak just keep showing up.   Column:… (Show more)

I want to determine the concentrations of CO, CO2 and H2 in syngas samples using mass spectrometry as I currently do not have the right GC column for it. Is it possible to do this? Can anyone guide me with the protocol for this? My setup consists of a GC column (HP-5). I will be manually injecting the samples and they have to pass through the… (Show more)

Click to view contentDoes anyone knows how to delete an old sample in the Run Queue Sequence? This sample cannot be deleted as normal and it is always present in the sequence queue. I'm using ChemStation for LC 3D systems Rev. B.04.03 [16]     Thanks!   Martin

Hi, I'm new to HPLC and amino acids analysis, therefore I have some questions that I need advise on. Forgive me for the long writing below, as I think it's better to clear out my methods before asking any questions.   Background Information: My laboratory has an Agilent 1260 HPLC with quan pump vl, G1321B 1260 FLD, G1314B 1260 VWD VL and auto… (Show more)

Hi everyone. I have an SC (suspension concentrate) product in which both actives have different behaviours in chromatography because one of them (gliphosate) is water soluble but the other (difluphenican) is not, so it is in suspension. The method that we have got is not for both actives, but for separating one by one, with different columns for… (Show more)

Click to view contentWhen I create a report, I want to use the function "Each Signal in full Scale"   The Problem is that the Injection Peak messes al up. Is there a way to ignore the peak but still show it ?   I know I can use the Scale Settings, but I want to insert it in all the reports.   Thank You

Hello, I am trying to run a packed column on a 7890 GC.  As far as I know, the system is setup correctly in terms of hardware.  I am pretty new with packed columns on an Agilent GC, so I am not sure where to even begin in terms of method settings. I am looking for optimal method settings.  I am running phenethyl alcohol as a standard with He as… (Show more)

Hello,   I got some questions concerning some parameter which can´t be found in the Open Labs 2.1. We currently using a GC 7890B with a HS 7697A. And I try to transfer the methods from our old 7890A.   1.) Chemstation none   Open Labs " Injection Type Standard"  What does this exactly mean. 2.) Chemstation none   Open Labs  "L1 Airgap" I… (Show more)
