It's often difficult to tell when to change filaments. It depends on use, samples, gases, gas cleanliness, and number of tunes. Certainly inspect them when the source is out for cleaning. If the wire is smooth and clean it's fine to reinstall. If the…
Hello jeremy_lai ,
There are details about adding additional qualifiers and ISTD information in this discussion.

Hello Darija ,
You may want to investigate using the blank offset option for the calibration curve. Details can be found in this discussion.

All our packed columns come already with a frit on inlet and outlet sides. Their porosity is smaller than any glass wool could be. If you still want to have a liner, please use our GC Liner Selector | Agilent

You've got column in your column. A bad cut usually just results in tailing. Doesn't sound like the rear was touched, recut the inlet side and try again.
Hello,
No, you cannot create custom sample types in CDS. You can use an existing field like sample label to mark specific injections if you need more delineation than the sample types can provide.

Hello,
To check if you have access to a core facility in iLab, log into your iLab account and navigate to the core facility's page. If you are not prompted to request access and can view sections such as “About our Core,” “Request Services,” or “Schedule…
Hi Sabbas,
if you have measured a batch and click the print button, all method parameters are shown in the report. I’m not sure if you can print the report of method solely without having measured a sample. I would in that case just measure a blank…
