Additional Information
Symmetry C4 Sentry Guard Cartridge, 300Å, 5 µm, 3.9 mm X 20 mm, 1K - 30K, 2/pk Symmetry columns continue to set the standard for HPLC drug testing, offering you confidence in your HPLC methods' long-term compliance. There's no need to sacrifice peak shape, selectivity, column-to-column and batch-to-batch consistency, or other essential performance parameters. Particle sizes, chemistries, and diameters are all available. The Symmetry C4 Sentry Guard Cartridge protects the Symmetry Column and provides a cost-effective approach to extend the life of the column by minimizing particulate matter and chemical pollutants. Symmetry C4 Sentry Guard Cartridges are typically offered in two designs: one for use as an integral part of the Waters Cartridge Column with reusable end fittings and another for use with any HPLC Column. Both of these designs make it possible to replace Sentry Guard Cartridges without the use of tools. The Symmetry C4 Sentry Guard Cartridge protects the Symmetry C4 Column, allowing it to produce the sharpest peaks for biomolecules and additional peak capacity for complicated tryptic maps. This is made feasible by the use of ultrapure silica that is produced. The end result is a high-purity analytical column with very little silanol activity. The column is additionally packed to provide the highest efficiency and reproducibility of any product on the market, providing you with better precision for impurity and stability tests, more accurate quantitation, and adaptation to more challenging procedures.

The Reversed-Phase QC Reference Material is a highly complicated reference material mixture that comprises components that may be difficult to separate. It is intended to give this complexity and is suited for routinely performing difficult experiments. It is compatible with a wide range of column chemistries and dimensions, as well as system hardware.

FAQ
What Causes My LC System To Shut Down On A Recurring basis? To enhance system security and safeguard the columns and equipment, HPLC pumps and systems feature built-in overpressure protection. The pump may shut off to protect the LC system if the system is set too low or there is too much back pressure. Other explanations could include cleaning the lines or eliminating residual or crystallized material that is obstructing or choking the system.
