Impact/Purpose:
Lawrence Livermore National Laboratory (LLNL) supplies ultra-dilute (10 µg/mL) chemical warfare agent (CWA) standards to the Environmental Response Laboratory Network (ERLN) laboratories to allow the use of authentic standards to assist in analyses required for a remediation event involving CWAs. For this reason, it is important to collect data regarding the shelf-lives of these standards. The instability has the potential to impact quality control in regional ERLN laboratories, resulting in data that are difficult to interpret. Thus, this study investigated the use of chemical stabilizers to increase the shelf-life of VX standards. VX standards with long shelf-lives are desirable, as long shelf-life would significantly reduce the costs associated with synthesizing and resupplying the ERLN laboratories with VX.
