I am going to reference you to the threshold calculation in the OpenLab Help (2.4): If I am understanding your question correctly, if you manually specify a sensitivity of 0% it means that no match between spectra is required to pass the impurity check. 3.

Witryna8 cze 2008 · The impurity peak is compared with the active peak in (1) diluted 1 to 100. (2) eg if the peak area of impurity in (1) was 50% of the peak area of the active in (2) the impurity level would be estimated as 0.5%. This kind of method can be found in BP and USP. No Tswett. WitrynaImpurity control is an essential aspect of quality control in individual monographs of the Ph. Eur. In this module, you learn about the Ph. Eur. policy on impurity control. It covers all types of impurities, whether they are organic, inorganic (including elemental impurities), solvents or DNA-reactive impurities such as N-nitrosamines. circled cc
