If you have data associated with a worksheet you cannot make modifications to it. Depending on your software version, you will need to either do "Save As" and give it another name, or create a new worksheet from template. Then the new worksheet will not…
Hello. You have to adjust Nitrogen pressure to get the blue bar inside green area. Pressure regulator is located on the right side of the 4107. It should be ~ 600kPa.
Hello mipastor,
Thank you for your response. I think we do have problem with the MS2 heater. Agilent customer support hinted that it might be sensor problem or the board so service engineer will have to take a look.

You do this with a Restek column! You cannot get a better resolution by changing just parameters with this cphase. You need a different selectivity to have a chance, maybe use a DB-WAX UltraInert.
For glucose a 87H type is ok as it uses Ion Exclusion Chromatography for the separation, the phases contain benzenesulfonic acid group (and will interact with anions in ion exchange mode). Phosphoric acid does not interact with sulfonic acid groups as…
thanks for sharing the information. It saved my day. But to delete the mentioned file I had to call helpdesk to grant me permission. No way to delete with my regular credentials.
