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-L80, with 9% carbon, offers retention similar to C8, but with unique selectivity imparted by its high hydrogen-bonding capacity.
YMC’s Guard Column Cartridge Systems for HPLC accept cartridges of 1.0, 2.1, 3.0, or 4.0mm inner diameters – in either 10mm or 20mm lengths. Cartridges are available with a comprehensive selection including all stationary phase chemistries offered by YMC, ensuring compatibility between the guard column and the analytical column. Assembly is tool-free, simplifying cartridge replacement.
YMC Guard Column Cartridges require the use of a holder, P/N: XPGCHP1 for 10mm length and P/N: XPGCHP2 for 20mm length.
