Designed to integrate seamlessly into laboratory operations, the Hplc Guard Columns (Analytical) Nucleodur ® Hilic offer robust protection for your primary HPLC column against contamination. With a particle size of 5 μm and a length of 4 mm, these guard columns are designed to fit securely within a guard column holder, positioned between the injector and the HPLC column. Featuring a hydrophilic interaction chromatography (HILIC) separation principle, they are ideal for use with acetonitrile-water eluents, offering a specific surface area of 340 m²/g and pH stability ranging from 2.0 to 8.5. By using these guard columns, you can extend the lifespan of your main column, ensuring optimal performance and minimal downtime in your analytical lab.
