20 Pesticide Mix Standard [186006348]

The 20 Pesticide Standard Mix is intended for use with the Waters Pesticide Screening Application Solution with UNIFI. This application prepares laboratories to test more food and environmental samples for increasing numbers of residues and contaminants not just at, but below, regulatory limits. The Waters Pesticide Screening Application Solution is custom-built to minimize both false-positive (non-compliant) and false negative (compliant) findings. Now, for the first time, scientists will be able to reliably report the presence or absence of pesticide residues, easily streamline workflows, and increase the speed of analysis of complex matrices.

The 20 Pesticide Mix Standard contains 10 μg/mL of each of the following pesticides:

  • atrazin
  • atrazin-desethyl
  • cyanazin
  • sebuthylazin
  • simazin
  • terbuthylazin
  • hexazinone
  • chlortoluron
  • diuron
  • linuron
  • metobromuron
  • metoxuron
  • monolinuron
  • metolachlor
  • methamidophos
  • acephate
  • methomyl
  • dicrotophos
  • buprofenzin
  • fenpropimorph in acetonitrile 


A 1 mL volume of this standard is provided in an amber ampule.

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.
