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.
Guard columns are recommended for challenging matrices or for use as trapping columns. YMC capillary guard columns are connected directly to the analytical column using the supplied column coupler.
A column coupler is supplied with every pack of YMC capillary guard cartridges to guarantee an optimum connection with low dead volume. A polymer-based (PCTFE) coupler is provided for 1/16” columns, while a stainless steel coupler is provided for 1/32” columns. Additional couplers can be purchased separately if required.
Columns, Guards and Accessories are only available for purchase online in North America or through our distributors.
To purchase consumables outside North America, please find your local distributor.
