HPLC Columns & Accessories

Browse our HPLC and UHPLC columns for greater separation process.

Supelco® HPLC and UHPLC columns meet today’s demands of fast U/HPLC, LC-MS, and biopolymer separation, as well as regulated pharmacopeia and agency methods within various industries. Supelco® HPLC products are available with Fused-Core® particle technology, monolithic silica, and fully porous particles, including ultra-pure silica. In addition, polymeric particles, alumina oxide, and zirconia particles are available for high pH stability.

Superficially porous silica particles (SPP)/Fused Core® Technology

Superficially porous silica columns deliver higher speed and efficiency than fully porous particles of the same size. Fused-Core® HPLC columns like Ascentis® Express and BIOshell™ can convert any HPLC system into a fast HPLC workhorse with maximum speed and performance.




Monolithic silica

Monolithic silica-based Chromolith® HPLC columns allow rapid separations at very low column backpressure with high matrix tolerance and extended column lifetime, thus making them ideal products for high throughput and cost-efficient analyses of matrix rich samples. Chromolith® HPLC columns are made from monolithic silica with the bimodal pore structure having 2 µm macropores and 13 nm mesopores. This structure leads to various key advantages to the column.

Chromolith® WP column is a wide pore (300 Å) monolithic silica column made up of a single continuous rod of high purity, porous silica. This column has shown great potential compared to conventional columns with its consistent performance over a longer lifetime. In addition to various RP-phases a Protein A affinity column and an epoxy column, enabling customer specific modifications, are available.

Fully porous silica particles (FPP) Type B (high purity silica)

  • Discovery® HPLC columns are efficient for the analysis of biomolecules and small molecules. These columns have polar and non-polar bonding, with unique retention, selectivity, and no-bleed properties for LC-MS applications.
  • The Ascentis® bonded phases have a wide range of selectivity. Type B silica makes the column inert, stable, and reproducible. The high surface area of the silica is suitable for high, preparative loading capacity.
  • Purospher® STAR HPLC and UHPLC columns are best suited for the peak-tailing free separation of basic, neutral, and metal chelating samples. Their superior performance and stability allow maximum flexibility in method development with extended pH stability.
  • Titan™ UHPLC columns with 1.9 µm fully porous monodisperse silica, surpass other UHPLC columns with high performance at low cost. The columns are stable over a range of UHPLC flow and pressure conditions.
  • SeQuant® HILIC (hydrophilic interaction liquid chromatography) HPLC columns carry densely bonded, zwitterionic functional groups. These columns are available in a variety of lengths, particle sizes, and pore dimensions while showing an exceptional reproducibility and robustness.
  • Kromasil® HPLC columns show excellent mechanical and chemical stability with high surface area and a narrow pore size distribution resulting in an extended lifetime and high loading capacity. (only available in the US)
  • Sepax® HPLC columns are highly porous silica-based columns mainly utilized for peptides and protein analysis.

Fully porous silica particles (FPP) Type A (conventional silica)

  • Supelcosil® silica-based HPLC column line has a wide range of bonded phase chemistries, with the particle sizes and column configurations ranging from microbore to preparative scale. These columns show great efficiency for polar, nonpolar, and charged analytes.
  • LiChrospher® and Superspher® HPLC columns are highly versatile and reliable, proven in thousands of established HPLC methods.
  • LiChrosorb® HPLC columns are packed with irregular silica particles ranging from analytical scale 5µm to large particles sized for production scale.
  • TSKgel® HPLC and UHPLC columns are available for gel filtration, gel permeation, ion exchange, reversed-phase, hydrophobic interaction, hydrophilic interaction, and affinity chromatography. (only available in the US and Europe)

Fully porous polymeric particles

  • apHera™ reversed-phase and amino HPLC columns are stable at the pH range 2-12 and are amenable to washing with alkaline solutions. They are ideal for the analysis of peptides, small proteins, carbohydrates, polar drugs, and organic acids.
  • Supelcogel® HPLC columns are packed with polystyrene-divinylbenzene co-polymer (PS-DVB) making them chemically stable. The two variations of PS-DVB co-polymer (6% and 8% cross-linked) maximize the separation process of the samples.
  • Hamilton Polymeric Reversed Phase HPLC columns are extremely inert, efficient, and durable, with high mechanical and thermal stability.
  • TSKgel® HPLC and UHPLC columns are available for the separation of proteins, peptides, and other biomolecules. The columns containing silica and methacrylate particles with different pore sizes can accommodate analytes with a wide range of molecular weights. (only available in the US and Europe)

Chiral HPLC Columns

We have a wide range of chiral HPLC columns for various applications.

  • Astec CYCLOBOND™ Chiral columns have bonded cyclodextrin phases that allow selective chemical separation of organic molecules.
  • Astec CHIROBIOTICTM Chiral columns are based on macrocyclic glycoproteins bonded to high purity silica gels available for LC-MS chiral applications.
  • Astec Cellulose DMP Chiral columns with spherical, high-purity porous silica coated with DMPC (3,5-dimethylphenyl carbamate); can separate a wide range of chiral compounds under normal phase, polar organic, and SFC conditions.
  • Astec Copper Ligand Exchange Chiral columns are beneficial for resolving hydroxy acids, amino acids, bi-functional racemates, and other amines.
  • Protein-based Chiral columns utilize natural proteins immobilized onto silica support to provide enantiomeric selectivity.
  • Astec Polycyclic Amine Polymer Chiral columns offer a bonding technology, mainly used in the normal phase, for the separation of racemic compounds.
  • Kromasil® Chiral HPLC columns contain cellulose and amylose-based chiral stationary phases bonded to premium spherical silica. (only available in the US)
