In the previous post, I talked about the merits of automated sampling in the dissolution workflow . Here, I will provide some information about how to validate your automated dissolution system, using the 850-DS Sampling station from Agilent as an example…
You might be able to use HPLC-SEC on those with an Aquagel-like column. Check these literature links for help:

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.
Agilent offers these two services for the IDP-7 Dry Scroll Pump: 1. The Agilent Rapid Exchange Service replaces your pump with a refurbished one • You can send your unit back (exchange) once the replacement unit arrives • Warranty period is 1 year from…
hello,
How to use the Add-ins Blank substraction in Mass Hunter V10.1 without a calibration curve? It seems like it is not possible without a calibration curve but I'm doing semi-quantitative work so I don't have a calibration curve.
Will that feature…
