    Aug 11, 2014 · Hi I'm now analyzing chromatographic profile of the Peppermint oil using EP method, and I have some problems with understanding how to use disregard limit. In method is told: "The area of the principal peak in the chromatogram obtained with reference solution (b) (0.05%)" Solution (b) contain only 1 standart substance A. On chromatogram I see only 2 peak, Standart substance A and 1 impurity, with peak area 1.5 and 1.6. What I need to do next, and how to use this disregard limit?

    Jul 12, 2016 · The ICH defines a Reporting Threshold as "A limit above which (ie greater than) the impurity should be reported" so in Empower 3 Impurity tab if I put 0.05 in the reporting threshold then Empower will flag any value GREATER THAN 0.05. But my impurity method states that "disregard any impurities less than 0.05%" so in order to include values of 0.05 upwards do I have to adjust the reporting threshold value to 0.04 to reflect this, similar to how RANGE in Empower treats the lower value as ...

    Could you please advice in respect to an impurities calculation issue. We have developed / validated a method where impurities are calculated by the known formula: %imp= (Atest/Aref)* limit. Comparison of the % percentage for an unknown imp. with specific rrt with the %area presented in the chromatogram shows really high differences. Is this normal?? eg: impurity calculated with the method formula: 0.015% impurity as given in the chromatogram %area: 0.22!!! Forced degradation in acidic ...
