Waters, 186002005, Atlantis Silica HILIC Sentry Guard Cartridge, 100Å, 3 µm, 2.1 mm X 10 mm, 2/pk

Atlantis HILIC Silica columns are used in combination with high organic mobile phases (>80% acetonitrile) to provide retention of analytes that are simply too polar to be retained by reverse-phase chromatography. HILIC separation mechanisms provide orthogonal analyte selectivity compared to traditional chromatographic reversed-phase approaches.

Additional Information
Atlantis Silica HILIC Sentry Guard Cartridge, 100Å, 3 µm, 2.1 mm X 10 mm, 2/pk Atlantis HILIC Silica columns and cartridges are used in conjunction with high organic mobile phases (>80% acetonitrile) to retain analytes that are simply too polar for reverse-phase chromatography. When compared to traditional chromatographic reversed-phase approaches, HILIC separation mechanisms provide orthogonal analyte selectivity. To extend the life of your analytical column, use the Atlantis Silica HILIC Sentry Guard Cartridge. The lab equipment complements the analytical column's performance by removing chemical and particulate contamination from the mobile phase stream. The Waters Atlantis Silica HILIC Sentry Guard Cartridge is designed to work with the Atlantis HILIC Liquid Chromatography Columns. Due to the fact that the analytical column is constructed using the same packing materials, the lab equipment has been optimized to provide performance at the same level. The Atlantis Silica HILIC Sentry Guard Cartridge is a single unit that attaches to the column directly. The Atlantis Silica HILIC Sentry Guard Cartridge, like all Waters equipment, is manufactured under the strictest cGMP, ISO 9001 conditions, and each unit is tested and certified for its use, ensuring that it will deliver optimal performance and improve the selectivity, sensitivity, and speed of your analysis. Every step of the manufacturing process is strictly controlled and monitored to ensure that you only receive the highest quality laboratory equipment. The Atlantis Silica HILIC Sentry Guard Cartridge extends the life of your UPLC analytical columns without compromising their chromatographic analytical performance. This is accomplished by removing unwanted pollutants from the columns while maintaining the separation efficiency of the UPLC, UHPLC, and HPLC.

FAQ
How Much Time Does It Take To Change A Column? Column changes are an effective technique for method development in HPLC, allowing flexibility to switch columns as required. When replacing a column, it is important to prevent air from entering the column inlet. To achieve this, slowly introduce solvent from the injector outlet line to fill the inlet fitting of the new column. Before injecting a sample, it is advisable to flush the column with a minimum of six column volumes of fresh solvent to ensure proper re-equilibration. The initial injection is typically disregarded, as subsequent injections, starting from the second one, tend to exhibit good reproducibility.
