2-AB Dextran Calibration Ladder [186006841]

The 2-AB Dextran Calibration Ladder was developed to help take full advantage of the BEH glycan column, to assist glycan profiling. The glycan profile obtained from UPLC-HILIC/FLR systems can be calibrated against the 2-AB labeled dextran ladder and assigned with glucose unit (GU) values. This calibration ladder provides good peak shape and reliable identification from 2 to 30 glucose units, which is twice as much as the other dextran ladder standards. This feature improves the large glycan retention time assignment.

This standard is packaged in a Waters TruView Vial (ideal for peptides) as 200 µg of lyophilized solid per vial for direct solubilization and injection if desired. Recommended solubilization is in 100 µL of DI water and 100 µL of acetonitrile for a 200 µL total.

Store at -4 °C upon arrival.

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.
