PRP-h5 polimeric reversed phase columns are ideal for applications that require a high degree of column-to-column and batch to batch consistency (quality assurance, clinical trials). Unlike C8 or C18 columns, PRP-h5 has no stationary phase coating. The integral reversed phase characteristics of the PRP-h5 column eliminate the need for special coating techniques. Since there is no stationary phase to hydrolyse, the column maintains its performance characteristics longer than many C8 or C18 columns. PRP-h5 columns are packed with a poly(styrene-divinylbenzene) material.

Achieve superior reversed phase (RP) oligonucleotide separatons using the DNAPac™ RP HPLC columns. The unique chemistry is designed for analysis of oligonucleotides and double-sranded (DS) DNA/RNA fragments using LC-UV or LC-MS. The column chemistry provides excellent performance under a broaed range of pH, temperature and mobile phase composits.

Supplier: CHIRAL TECHNOLOGIES

CHIRALPAK® QN-AX and CHIRALPAK® QD-AX are enantioselective weak anion-exchange (AX) HPLC columns. The chiral selectors for CHIRALPAK® QD-AX and CHIRALPAK® QN-AX anion exchange phases are based on complementary quinine (QN) and quinidine (QD) derivative selectors bonded to high efficiency 5 µm diameter spherical silica. The structure of these selectors is such that a tertiary amine is located in a three-dimensional cleft surrounded by additional hydrogen binding sites and a large aromatic group. This combination provides excellent separations of chiral acids.

Supplier: Thermo Fisher Scientific

Protein desalting spin columns are designed to desalt or exchange buffer of protein samples with volumes of 30 to 120 µl. These devices have exceptional desalting characteristics with ≥95% retention of salts and small molecules while providing excellent recovery of proteins greater than 7 kDa. Multiple samples can be processed in less than five minutes without cumbersome column preparation steps.

Supplier: TOSOH Bioscience

TSKgel® SW size exclusion columns are widely used for aqueous analysis and isolation of proteins, antibodies, enzymes, nucleic acids and other biological macromolecules.
