Columns for Polymer-based Reversed Phase Chr (RP) + Surfactants, detergent - Size exclusion (SEC)omatography (Asahipak GF, ODP2 HP, RSpak RP18, DS, DE, DM, NN, JJ) (G50)

Features

Asahipak GF

• Polymer-based SEC columns exhibit high solvent durability (multisolvent column)
• Supports both aqueous and organic solvents
• Suitable for the analysis of surfactants, polyelectrolytes, proteins, hormones
• Effective for drug analysis in biological samples by using column switching method to remove proteins
• Useful for LC/MS analysis

ODP2 HP

• Provides nearly twice as large theoretical plate number compared with generally available polymer-based Reversed phase columns
• Enhanced retention of high polar or basic substances compared with C18 silica column
• Small pore size suitable for RP analysis of small molecules (pharmaceuticals) in the presence of protein matrix
• Ideal for LC/MS analysis of high polar compounds
• pH stability: 3 to 12

RSpak RP18

• Large pore size is suitable for the analysis of proteins and peptides (biomolecules)

RSpak DS

• Suitable for Reversed phase analysis of highly hydrophilic substances, which cannot be retained well by ODS columns

RSpak DE

• Polymer-based columns, with similar polarity to that of C18 silica columns, can be used in general and wide purpose
• Wide working pH range (2-12), usable in 100 % water and buffer solutions

RSpak DM

• Polymer-based RP column
• Suitable for the analysis of amino acids and water-soluble vitamins

RSpak NN

• The packing material contains sulfo groups, and supports multimode (Reversed phase and cation exchange) analysis
• Ideal for analysis of complex samples containing neutral and ionic substances
• For amino acids, aromatic organic acids, basic nucleotides, vitamins

RSpak JJ

• The packing material contains trace amounts of quaternary ammonium groups, and supports multimode (Reversed phase and anion exchange) analysis
• Ideal for analysis of complex samples containing neutral and ionic substances (surfactants)
