Measuring the total organic carbon (TOC) content in pure water involves a risk of laboratory equipment contamination having a major impact on measurement values. Therefore, vials used for TOC measurements must be cleaned, dried, and stored very carefully. If those steps are not always performed, the reliability of measurement values can be compromised.
In contrast to conventional vials, Certified Quality (CQ) vial maximize reliability and enable higher workflow efficiency. They are prepared with strictly controlled manufacturing and cleaning processes that inhibit leaching of impurities into the vial down to extremely low levels. That makes them ideal for measuring pure water or low-concentration samples.
