How can the column parameters be tested?

Important parameters are the retention time, peaksymmetry and theoretical plates and maybe resolution. Every column comes with an attached quality certificate where these parameters were tested. Exact measuring conditions and sample amounts are mentioned on the certificate. The column parameters can easily be checked by re-running the standard test shown in the enclosed chromatogramm.
If you do not have the possibility to re-run the KNAUER standard test, you can also use other suitable substances and define your own parameters and criteria for evaluation.

We separate molecules and unite people.

Based in Berlin, KNAUER has been serving the sciences since 1962. We develop and manufacture scientific instruments of superior quality for liquid chromatography systems and components, including:

Analytical HPLC / UHPLC
Preparative HPLC
