We need to check if the peak purity angle is less than purity treshold. Where do I find these parameters (OL v2.5)?

Question

Hi, 
 We do not find 'peak purity angle' as a result in the table after running a spectral HPLC analyses. We use the 3D processing method. Does this parameter has another name in open lab? We are not that experienced with spectral analyses. 
 Thanks

Hello, 
 
 The reported value you want to add is UV Purity for HPLC with DAD spectral data. If you want to know the calculations used, search UV Spectral Analysis in the OpenLab Help and Learning. The settings are in the method under spectra and UV Impurity Check tab.
