The analyte ranges you reference are for stock products that vary from lot to lot. These products are designed to be used as QC samples for drinking and wastewater analyses, and the variability in element concentration is intended to assist with these analyses. These products are all designated in our catalog with product codes “QCP-xxx” and we stock at least two different lots of each of these products; one lot with relatively low concentrations and one lot with higher concentrations. It may be helpful to review recent Certificates of Analyses for these QCP products on our website (https://www.inorganicventures.com/product-category/water-qc-standards), as they will provide detailed information about the absolute and relative concentrations you can expect for different analytes in each product. |
