YMC J’Sphere H80 Analytical Guard Columns

High Efficiency

The 4µm, 80Å silica support of J’Sphere columns provides high chromatographic efficiency, while the high surface area material (500 m2/g) offers exceptional interaction with analytes.  This combination provides excellent peak symmetry.

Choose Your Retention

The J’Sphere series of columns combines three different carbon loads (9%, 14%, and 22%) with a range of hydrogen-bonding capacities to provide three columns that differ in retention and, oftentimes, selectivity as well.  Users can exploit these differences during method development and choose the best column to suit their separation.  ODS-H80, with 22% carbon, is the most hydrophobic and hydrolytically stable.  It resists attack by both high-and low-pH solvents and has proven stable at pH 1.1 to 9.3 for over 500 hours.
