24 pecheck Performance Evaluation Standards pecheck standards are cost effective performance evaluation standards for routine analysis compliance testing. Available for mineral, nutrient, and solids testing in water/wastewater matrices. pecheck standards are certifi ed through a comprehensive roundrobin study providing independent verifi cation from multiple laboratories levels of concentration available. 20 ml vials. No pipetting necessary. Just dilute to volume. Each standard dilutes to 1 L. Certifi cate of Analysis listing consensus values as well as confidence and tolerance intervals. See page for a sample pecheck Certifi cate of Analysis Prepared in large batches. Select the concentration level that meets your needs. Eliminate a source of potential error, save time with single step preparation. Monitor lab performance in a cost effective, simple manner. Same lot number available time after time allows the possibility of control charting.
