YMC J’Sphere M80 Capillary 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-M80, with 14% carbon, is an inert, efficient phase with moderate hydrophobicity and hydrogen bonding capacity.


Capillary Guard Columns: Features & Benefitsymca_3

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.
