Polystyrene ReadyCal Standards 2 mL Kit [WAT058931]

The Polystyrene Ready Cal Standards 2 mL Kit is used for routine MW determinations of polystyrene samples. This kit contains 10 full sets of polystyrene molecular weight range standards from 400 to 2,000,000 Da.

Each ready-to-use set of polystyrene calibration standards set consists of 3 different vials with (4) different MW polystyrene standards per vial. Standards get reconstituted in the 4 mL vial with your choice of solvent. The MWs noted are representative values only. The COA will contain the actual MW, the actual MW value could vary from the representative weight especially for the very high MWs and the actual MWs may vary from lot to lot.

The Polystyrene Ready Cal Standards 2 mL Kit contains a total of 30 vials which yield 12 calibration points per 3 vial set. Just add solvent to the vial, let it stand 2 hours, shake gently and load into your autosampler for analysis. Each kit comes with a Certificate of Analysis and detailed instructions for proper usage. The kit contains the following MWs; 560, 1200, 3200, 8000 , 18000, 33000, 62000, 120000, 280000, 560000, 1200000, 2500000

Store refrigerated 2-5 °C upon arrival for best results.

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.

Calibration

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.

Performance

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.

Tuning

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.

Hazardous

This product contains hazardous material which requires special freight handling. Additional charges may apply.
