SPSFAM Heavy Metals ERP Book

LOD is some cases and in other cases set the LOQ as the lowest calibration. LOQs are calculated. Reporting limits are arbitrarily set. The "LOQ" should be renamed "LOQ/Reporting Limit". Also the statement "... and the LOD was calculated as 1/3 of the LOQ" should be removed. Again, this statement assigns an arbitrary value to the LOD. The following suggestions refer to the MLT report. 1. The Annex G links need to be activated. 2.
