Extractables & Leachables Screening Standard [186008063]

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.

• Methylparaben (0.1 µg/mL+/- 1%)
• Propylparaben (0.1 µg/mL+/- 1%)
• Diethyl phthalate (0.1 µg/mL+/- 1%)
• Tinuvin P (1 µg/mL+/- 1%)
• Dibutyl sebacate (0.1 µg/mL+/- 1%)
• Diphenyl phthalate (0.1 µg/mL+/- 1%)
• 2-hydroxy-4-octyloxy benzophenone (0.1 µg/mL+/- 1%)
• Tinuvin 327 (1 µg/mL+/- 1%)
• TCP (0.1 µg/mL+/- 1%)
• Uvitex OB (0.1 µg/mL+/- 1%)
• Cyasorb 2908 (0.1 µg/mL+/- 1%)
• Irganox 1076 (1 µg/mL+/- 1%)
• Irganox 245 (0.1 µg/mL+/- 1%)
• Irganox 1098 (0.1 µg/mL+/- 1%)
• Tinuvin 360 (1 µg/mL+/- 1%)
• Ethanox 330 (Irganox 1330) (1 µg/mL+/- 1%)
• Uvinul 3030 (0.1 µg/mL+/- 1%)
• Irganox 1010 (1 µg/mL+/- 1%)

System Performance Standards Key

Set Up

Setup standards are used upon installation of a new system, start-up of a system which has been idle for a period of time, or to re-start a system that has been moved to a new location. These standards may include multiple components within a kit which allow step by step setup and calibration, or they can be single mixtures which will enable a full system assessment and initialization.


These standards can be used for instrument calibration. Calibration is usually performed at a frequency that minimizes the risk of being out of calibration, in addition to major events suc h as when the instrument is moved and upon any major repair. Calibration can be confirmed as often as your standard operating procedures recommend. Look for solutions to calibrate your MS mass accuracy and resolution, UV detector linearity, UV and Fluorescence detector wavelength accuracy, injector accuracy and precision, and solvent system flow rate accuracy.


Your system is comprised of many interdependent components working together. An issue with any one component can produce erroneous final results. All components performing correctly will produce results within an expected variability. Some of the system components include mobile phase, column, tubing, pumping, injecting, temperature controlling, detecting, data collection rate, and integration
parameters. An issue in any one of the components listed can affect your result.
Performance Check Standards should be utilized on a routine basis. This includes anytime a column is changed, a method is changed, the instrument is moved, or confirmation of system performance is desired. Confirming the performance of your system can be done on a system basis with suitability standards or per individual instrument component. Benchmark performance should be established after
calibration and confirmed regularly.


These Mass Spectrometry solutions are used routinely and are available for every ionization mode. Use the solution to optimize the mass spectrometer setting for optimal signal either manually or through Intellistart.
