QDa QC Reference Material [186007345]

The QDa Quality Control (QC) Reference Material is designed for use with Waters ACQUITY QDa Detector. It is intended to be used as a system benchmarking standard. 

The mix is extremely versatile and appropriate for a vast majority of column chemistries and dimensions. It is adaptable to a wide variety of separation methods.
When used consistently and control charted, the QC Reference Material will:
  • Increase confidence in your results
  • Reduce troubleshooting and re-analysis
  • Enable cross lab result comparisons 


The QDa QC Reference Material is a 1 mL solution containing:  

  • Acetaminophen 100.0 μg/mL
  • Caffeine 45.0 μg/mL
  • Sulfaguanidine 50.0 μg/mL
  • Sulfadimethoxine 10.0 μg/mL 
  • Val-Tyr-Val 25.0 μg/mL
  • Verapamil 6.0 μg/mL
  • Terfenadine 6.0 μg/mL
  • Leucine Enkephalin 25.0 μg/mL
  • Reserpine 18.0 μg/mL Dissolved in 23.5% LC-MS
  • Acetonitrile 76.5% LC/MS Water, 0.007% Formic Acid   


Store refrigerated 2-5 °C.

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.
