Recent developments in LC column technology have now made the use of sub 3 µm particle packing materials practical. These smaller particle size materials allow higher mobile phase linear velocities to be used, without the decrease in separation...

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...

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,...

Scaling up of biological separations is practical and economical using Brownlees Prep-10 cartridges. These 10 mm ID cartridges, packed with Aquapore 20 mm, 300 A sorbents, are available in 30 mm, 100 mm and 250 mm cartridges.The unique 100 mm and 250 mm...

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...

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...

The 33 x 4.6 column is capable of very rapid analyses, as short as one to two minutes. These columns are available in economical packs of five and require holder 470-44888. The 83 x 4.6 column with >10,000 plates can separate many complex mixtures in...
