The XBridge BEH C18 Sentry Guard Cartridge, 130Å, 3.5 µm, 4.6 mm X 20 mm, is a tool for protecting your analytical column in high-performance liquid chromatography (HPLC) systems. Designed to extend the lifespan of your analytical column and ensure consistent, high-quality results, this guard cartridge is part of the XBridge BEH family, which is renowned for its durability and exceptional chromatographic performance.

One of the standout features of the XBridge BEH C18 Sentry Guard Cartridge is its advanced hybrid particle technology. By combining the benefits of both silica and polymeric particles, this technology enhances the efficiency and robustness of the cartridge, making it ideal for a wide variety of applications. Additionally, the trifunctionally bonded C18 ligand offers a wide pH range (1-12), making it versatile for use with different mobile phases while also ensuring excellent peak shape and resolution.

The cartridge"s low silanol activity further enhances its performance by minimizing unwanted interactions between analytes and the column, which leads to improved peak shape and higher accuracy in your results. Whether you are conducting pharmaceutical analysis, bioanalysis, environmental analysis, or food and beverage testing, this cartridge provides reliable protection for your analytical column, allowing you to achieve precise quantification of analytes in complex samples.

The Sentry Guard design is another key benefit of this product. It incorporates frits that trap contaminants before they can reach and damage the analytical column, effectively preventing performance degradation. This protection not only ensures more consistent results but also significantly extends the column"s lifespan, saving both time and costs associated with column replacement and maintenance. The 4.6 mm x 20 mm guard cartridge is packaged in pairs, offering convenience and value for labs requiring high-throughput or frequent analysis. Applications for this guard cartridge include a wide range of industries. In pharmaceutical analysis, it can be used to separate and quantify active pharmaceutical ingredients and impurities. In bioanalysis, it aids in the analysis of biological samples such as blood and plasma.

Environmental analysis benefits from its ability to detect pollutants in water and soil, while food and beverage industries use it to identify contaminants and additives in their products. The cartridge is also valuable in quality control processes, where consistent and accurate monitoring of product quality is critical.

Overall, the XBridge BEH C18 Sentry Guard Cartridge is a high-performance, easy-to-use solution that provides essential protection for your analytical column, ensuring reliable and reproducible results across a broad range of HPLC applications. With its advanced particle technology, wide pH range, and robust contaminant-trapping design, this cartridge is an invaluable asset for any lab aiming to maintain peak column performance and extend its analytical column"s lifespan.
