NewGuards are small guard cartridges, L x ID mm (15 mm x 3.2 mm ) packed with 5 µm or 7 µm sorbents. NewGuard cartridges prolong column life by eliminating particulates, contaminants, and strongly bound sample components. They act as...

Reversed-Phase Chromatography (RPC) is the most popular HPLC mode and is used in 60-80% of all applications. In RPC, hydrophobic groups (C18, C8, or C4) bonded to a silica support are used together with a mobile phase of water and organic solvent (e...

Polar Phase (Normal Phase) Chromatography (NPC) uses a polar stationary phase (unbonded silica, bonded amino or cyano group) together with a nonpolar mobile phase (e.g., hexane). NPC is useful for functional group analysis, isomeric separations,...

Ion-Exchange Chromatography (IEC) utilizes bonded ionic groups to separate ionic analytes. Retention is based on the affinity of various analyte ions for the stationary phase and various mobile phase parameters (e.g., pH, ionic strength).• 30 mm...
