WitrynaExtractable impurities can generate interfering peaks in a chromatogram or mass spectrum, making it difficult or impossible to identify or quantify analytes of interest. Therefore, it is important to use a sample preparation device that leaches minimal impurities into the sample.

Witrynaspreadsheet) of the data is recommended. Impurities should be designated by code number or by an appropriate descriptor, e.g., retention time. If a higher reporting threshold is proposed, it should be fully justified. All impurities at a level greater than (>) the reporting threshold should be summed and reported as total impurities.
