High Performance Liquid Chromatography (HPLC)
PL manufactures a range of HPLC macroporous polymeric supports for use at pH 1-14, available as packed HPLC columns in a range of dimensions, pore and particle sizes, and as process evaluation columns.
PLRP-S Columns
PLRP-S 100 Å is a highly crosslinked copolymer of PS/DVB. The column would be used for reversed phase HPLC, ion pair chromatography and ion suppression chromatography. It’s L21 column and designed for the high performance analysis of wide variety of small molecules, such as pharmaceuticals, food and other biochemicals.
PLRP-S 300 Å/1000 Å/4000 Å for peptide and protein purification
PL-SAX & PL-SCX strong anion and cation exchange resins are designed for the analysis of proteins and oligonucleotides with high capacity and high recovery, from analytical to preparative scale. Two pore sizes are available：1000 Å and 4000 Å.
PL Hi-Plex Columns are resin-based columns for the analysis of carbohydrates, saccharides alcohols and organic acids. Monodisperse packing. PL has designed a series of five basic column types：Ca, Pb, H, Na, Ag.
