HPLC guard column - requires Column Protection System guard column holder (REF 718966) - for main columns 2 mm ID. For protection of your main HPLC column from contamination, it is recommended to use guard columns. These short columns are placed into a guard column holder. The guard column holder in combination with a guard column inside is installed between the injector and the HPLC column. This installation prevents chemical impurities to reach the main column. Because a contamination could form an irreversible bond with the column packing material (stationary phase) and this can result in shorter column life.
HPLC guard column EC 4/2 NUCLEOSHELL Biphenyl - require Column Protection System guard column holder (REF 718966) - for analytical columns with 2 mm ID. Hydrophobic phase with alternative selectivity compared to classical C18 modifications. The separation principle based on two retention mechanisms - π-π interactions and hydrophobic interactions. This provides better retention of aromatic and unsaturated substances. This stationary HPLC phase is based on core-shell technology silica gel particles and shows excellent performance under highly aqueous conditions. Suitable for LC/MS due to low bleeding characteristics.
HPLC guard column EC 4/3 NUCLEOSHELL Biphenyl - require Column Protection System guard column holder (REF 718966) - for analytical columns with 3, 4 or 4.6 mm ID. Hydrophobic phase with alternative selectivity compared to classical C18 modifications. The separation principle based on two retention mechanisms - π-π interactions and hydrophobic interactions. This provides better retention of aromatic and unsaturated substances.
