Atlantis Silica HILIC VanGuard Cartridge, 100Å, 5 µm, 3.9 mm X 5 mm, 3/pk
Atlantis HILIC VanGuard Cartridges are used to extend the lifetime and performance of analytical columns by removing particulate contamination from the mobile phase stream. This cartridge is designed to protect all Atlantis HILIC analytical columns with 3.9 mm and 4.6 mm I.D. and 5 µm sorbent particles. To retain analytes that are simply too polar for reverse-phase chromatography, Atlantis HILIC Silica columns and cartridges are used in conjunction with high organic mobile phases (>80% acetonitrile). HILIC separation mechanisms provide orthogonal analyte selectivity when compared to traditional chromatographic reversed-phase approaches.
Use the Atlantis HILIC VanGuard Cartridge to extend the life of your analytical column. The lab equipment improves the performance of the analytical column by removing chemical and particulate contamination from the mobile phase stream. The Waters Atlantis HILIC VanGuard Cartridges are intended to be used in conjunction with the Atlantis HILIC Liquid Chromatography Columns. Because the analytical column is built with the same packing materials, the lab equipment has been optimized to perform at the same level.
The Atlantis HILIC VanGuard Cartridges, like all of Waters' equipment, are made in accordance with the most stringent cGMP, ISO 9001 standards. Each piece is tested and approved for use before shipping, ensuring that it will perform at its peak level and increase the selectivity, sensitivity, and speed of your analysis. Every step of the manufacturing process is strictly controlled and monitored to ensure that only the highest quality laboratory equipment is delivered to you.

What Is The Average Time It Takes To Change A Column?
Column changes are an effective method development tool in HPLC, and columns can be switched as needed. To avoid leaving air in the column entrance, fill the inlet fitting of your column with a slow flow of solvent from the injector outlet line. We recommend flushing a column with at least six columns of a new solvent before injecting a sample to re-equilibrate the column. The first injection should be ignored because the second, third, and subsequent injections are usually repeatable.
