TSKgel Amide-80 and TSKgel NH2-100 HILIC columns from Tosoh Bioscience are first class columns when it comes to separations of hydrophilic compounds like peptides, carbohydrates, polar natural substances, amino acids, oligonucleotides, organic polar acids and bases, even proteins. HILIC combines the advantages of the Normal Phase with those of the Reversed Phase Chromatography, without having to forego the common RP eluents li…

HPLC column

Widely considered the premium columns for analyzing biopolymers by GFC, TSKgel G2000SWXL, 5 μm columns are an excellent choice for small proteins and peptide separations.

The TSKgel Alpha-4000 column is packed with rigid, porous polymer beads which show minimal shrinkage or swelling in polar organic solvents (methanol, acetonitrile, DMSO, isopropanol, THF, and HFIP). This column is stable in a wide variety of organic solvents at concentrations up to 100%. The main application area for the TSKgel Alpha-4000 column is the analyses of polymers that are soluble in polar organic solvents up to 1…

The TSKgel OligoDNA RP and TSKgel TMS-250 columns incorporate 5 μm or 10 μm spherical porous silica with 250Å pores to allow unhindered access by large oligonucleotides and proteins respectively. Product highlights TSKgel OligoDNA RP:   - Contains a monomeric C18 bonded phase that is not endcapped.    - Available in 4.6 mm id and 7.8 mm id (both 15 cm length)TSKgel TMS-250:   - Exhaustively and repeatedly reacted with trime…

ZIC®-HILIC HPLC columns for the separation of all classes of polar and hydrophilic compounds. What is HILIC? HILIC or Hydrophilic Interaction Liquid Chromatography is a straightforward chromatographic technique for separation of many types of polar and hydrophilic compounds. To put it simple one can say that HILIC is a normal-phase (NPLC) type of separation but uses reversed-phase (RPLC) type eluents. In HILIC one has: A c…
