Additional Information
FAQs about XBridge BEH Amide Sentry Guard Cartridge How does the XBridge BEH Amide Sentry Guard Cartridge enhance the lifespan of analytical columns? The XBridge BEH Amide Sentry Guard Cartridge is designed to protect analytical columns by trapping particulates and strongly retained compounds, preventing them from reaching the analytical column, thereby extending its lifespan. What specific applications can the XBridge BEH Amide Sentry Guard Cartridge be used for? The XBridge BEH Amide Sentry Guard Cartridge is well-suited for hydrophilic interaction chromatography (HILIC) applications where it can provide extra protection in the analysis of sugars, glycols, and polar compounds. Can the XBridge BEH Amide Sentry Guard Cartridge be used with a wide range of solvents? Yes, the XBridge BEH Amide Sentry Guard Cartridge is compatible with a wide range of solvents commonly used in HILIC, including acetonitrile and water with various buffer systems. Is the XBridge BEH Amide Sentry Guard Cartridge suitable for UPLC systems? While specifically designed for high-performance liquid chromatography (HPLC) systems, the XBridge BEH Amide Sentry Guard Cartridge may also be used in UPLC systems if it meets the system's pressure requirements. How is the XBridge BEH Amide Sentry Guard Cartridge maintained to ensure optimal performance? To maintain optimal performance, the XBridge BEH Amide Sentry Guard Cartridge should be flushed with clean solvents after use and stored according to the manufacturer's recommendations when not in use.

FAQ
How do I avoid pressure spikes when starting up my XBridge Guard Cartridge? It is possible that a sudden high flow rate starting at 50-60 mL/min may contribute to initial disruption of the prep guard cartridge leading to the peak splitting and shortened lifetimes. It is recommended to start the flow rate up more slowly over a period of 5-10 minutes to avoid this issue.
