Hi.
I tried to confirm symmetry on Injection Results in OpenLAB WS Plus 2.3.
But it's unable to get this value.
Could you give me some tips on how to get this?
Thank you.

Hello,
I would guess the issue is you have not setup the system suitability section of the processing method. You need to select to calculate system performance and which type of calculations to do in the method.

Hello.
Thank you for responding so quickly.
I can see the value of symmetry as you referred to with Chemstation integrator being selected.
but if Ezcrom integrator is selected, it didn't show up.
I don't know between the difference.

Hello,
You might want to search the help and learning for symmetry, as I imagine what you are looking for is tailing. In OpenLab, the symmetry is calculated as a pseudomoment by the integrator which is why it is only displayed when using the CS integrator.

Symmetry
By most of the pharmacopeias, the symmetry factor of a peak is calculated by comparing the peak half-widths at 5%. In OpenLab, this factor is calculated and stored as the Tailing factor (see Symmetry Factor, Tailing Factor (USP)). In OpenLab, the symmetry is calculated as a pseudomoment by the integrator using the following moment equations:
