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.
In Acquisition you can access this cool function. I found something similar to check your samples. The only difference to the "Snapshot Function" is that you only can do that after the run is completed. But its still a very usefully function.
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 moreShow less)
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 moreShow less)
Does 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  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 moreShow less)
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 moreShow less)
I did a quick literature search and quickly found a number of applications where difluphenican was used in a reverse phase method with water and an organic as the two mobile phases. I am assuming you mean glyphosate and not “glyphosate”. It is extremely polar, with a logP of -4.6. Difluphenican has a logP of 4. While that is a bit…
When 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 moreShow less)
Hi mcolq01, I have moved your post to an application area so that it has more exposure. Packed column applications are rare today, I am hoping you get a connection with a user with a similar application. Regards James
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 moreShow less)
The Correct answers would be. Its in German sorry. Der Injection-Type definiert, ob Sie zum Beispiel eine standardmäßige normale Injection oder eine „Multiple-Injection“ durchführen wollen. Dies wird auch in der Hilfe erklärt. Sie haben es schon richtig vermutet. Dies wird in der Hilfe anschaulich mit Bildern beschrieben – hier ein Auszug: …
