The Extractables & Leachables Screening Standard is designed to complement the Waters Screening Platform Solution with UNIFI™. This mix is composed of 18 common polymer additives allowing users to evaluate and benchmark high resolution LC-MS systems.
The Extractables & Leachables Screening Standard covers a mass range of up to 1176 Da, supporting both positive and negative ionization modes. Compounds were specifically chosen due to stable retention times and easy evaluation of mass accuracy. Simplify your screening workflow and eliminate time consuming standard preparation steps when analyzing samples for unknown contaminants.
The standard mix is provided in a Waters Crimp Top vial for direct injection and contains the following compounds in 2 mL MeOH.
