The Total Dissolved Solids (TDS) standard provides ongoing batch level QA/QC samples for the TDS analysis at an affordable cost. Create a Lab Control Sample (LCS) by transferring bottle contents into a graduated cylinder or volumetric flask, pour to volume and analyze. An acceptability range of ±3 standard deviations is provided for each parameter. MSDS and Certificate of Analysis with NIST traceability and instructions for use are included with each set.
