HPLC columns for every application

Find the right column from over 140,000 HPLC columns from more than 50 different manufacturers such as Agilent, Macherey-Nagel or Merck. We also offer our own brand of Altmann Analytik HPLC columns as a high-quality and cost-effective alternative. Compare prices and the application possibilities of the various manufacturers. If you are unable to find a suitable HPLC column, please feel free to contact us.

Prior to the development of the Reversed Phase (RP), Normal Phase Chromatography was the most common separation mode. We offer Normal Phase (NP) HPLC columns by all well-known manufacturers here.

In Normal Phase Chromatography, the mobile phase is non-polar and the stationary phase is polar (common: silica gel). This technique relies on the interaction of analytes with polar functional groups on the surface of the stationary phase. This interaction is strongest when using non-polar solvents as the mobile phase. The least polar compounds elute first and the most polar compounds elute last.

Normal Phase Chromatography is a very effective separation method because a wide range of solvents can be used to fine-tune the selectivity of a separation. However, it has become less popular with many chromatographers because of the complexity involved. Under certain conditions, long equilibration times or reproducibility problems may occur. This is due mainly to the sensitivity of the technique to the presence of low concentrations of polar contaminants in the mobile phase. Controlling these problems effectively produces better chromatograms than reverse phase methods as the commonly used solvents have a lower viscosity.

HPLC columns for Reversed Phase (RP) Chromatography

In Reversed Phase Chromatography, the polarity of the phases are "reversed". The mobile phase is polar and the stationary phase is non-polar. As it is one of the most popular separation modes in chromatography, all related products of all well-known manufacturers are available here.

The non-polar side chains in Reversed Phase Chromatography columns are bound either to a polymer or to a structure made of silica gel, which leads to them being hydrophobic. The longer the chain, the more non-polar the phases are. Polar analytes are eluted from the column first, followed by the non-polar analytes. Reversed phase is more widely practised than normal phased as they can be used universally for polar and non-polar analytes. In addition, this method is very sensitive and flexible as small changes in the composition of the mobile phase (e.g. salts, pH, organic solvents) or the temperature can completely change the separation properties of the system. RP-HPLC is used especially in numerous applications of UV spectroscopy (LC-UV).

Chiral columns for Chiral/Enantiomeric chromatography

Unlike normal HPLC columns, chiral or enantiomeric HPLC can also be used to separate and determine chiral compounds. This requires special chiral stationary phases that have fixed chiral functionalities. At Analytics-Shop, we have over 3,300 different chiral columns from different manufacturers, including the high-quality columns from Chiral Technologies as well as lower-priced alternatives of the same quality from YMC and Dr. Maisch.

Special columns such as chiral or enantiomeric HPLC columns are required to separate chiral compounds. With suitable interaction, these enable the separation of the enantiomers which have almost identical physical and chemical properties. In the simplest case, an enantiomer has only one chiral center. In larger molecules, however, there are often enantiomers with several chiral centers, which must then all have the "opposite" configuration In contrast, diastereomers have at least one chiral center that is the same and at least one that is different in configuration. Diasteromers usually differ in their properties and can therefore often be better separated. Therefore, sometimes a diastereomer is synthesized from an enantiomer to achieve (better) separation. A conventional solvent is used as the eluent.

UHPLC and UPLC® columns

With Ultra High Performance Liquid Chromatography (UHPLC), dramatic increases in resolution, speed and sensitivity of HPLC can be achieved by using short and thin columns. The particles of the filling material have diameters of less than 2 µm, which results in an improved separation performance compared to standard HPLC. The increased total surface area of the filling material gives the analyte a higher adsorption ability. Analysis times are reduced due to the shorter columns and less solvent is required.

Columns for Hydrophilic Interaction Chromatography (HILIC)

Hydrophilic interaction chromatography (HILIC) is a popular alternative to normal phase and reverse phase chromatography. Similar to NP, in the HILIC method, polar stationary phases are used, but with mobile phases comparable to those used in RP chromatography. The mobile phase typically consists of a high organic content (usually acetonitrile) and a low proportion of aqueous solvent/buffer or another polar solvent. In the HILIC method, water is the strongest eluent. A HILIC column is particularly suitable for separating highly polar substances such as carbohydrates, amino acids, bases, and alkaloids. An extensive range of HILIC columns from established quality manufacturer YMC is available in our shop.

Columns for Supercritical Fluid Chromatography (SFC)

Significant advantages of Supercritical Liquid Chromatography (SFC) columns compared to HPLC columns:

  1. Inexpensive: reduced solvent comsumption
  2. Environmentally friendly
  3. Time-saving: quick separation with high resolution
  4. Flexible: chiral and achiral phases

Supercritical fluids show low viscosities and higher diffusivities when used as a mobile phase, resulting in narrower peaks due to rapid diffusion and faster elution and less pressure drop through the column. Supercritical fluids combine the benefits of liquids and gases, hence enabling the SFC technique to combine the best aspects of HPLC and gas chromatography (GC). In most cases, a supercritical fluid such as carbon dioxide is used as the mobile phase. The low viscosity of supercritical carbon dioxide enables analytical separations that are 3-5 times faster than those for normal phase HPLC. The speed of SFC separations, the preservation of organic solvents and more concentrated product fractions make SFC a preferred chromatographic technique for separating and purifying chemical mixtures.

The use of high-performance preparative columns (internal diameter of 10 - 50 mm) with a large number of particle sizes from 3 - 20 μm leads to the quick separation and recovery of cleaned components.

Nano HPLC columns

Nano HPLC uses columns with very small inner diameters. Columns with internal diameters of 75 µm, 100 µm or 150 µm are commonly used. Due to the reduction in the internal diameter, injection and flow rates must be reduced which is particularly advantageous when only small or diluted sample quantities are available. The smaller nano HPLC columns lead to an increased sensitivity with lower solvent consumption. Nano columns are able to maintain a high concentration of the injected sample and to direct approx. 40-50 % of the sample to the detector. Nano HPLC has a high separation efficiency compared to the traditional HPLC technique.

Columns for Gel Permeation Chromatography (GPC) & Size Exclusion Chromatography (SEC)

GPC/SEC (Gel Permeation / Size Exclusion Chromatography) is a separation method in which the analytes are separated on the basis of their size, or rather their hydrodynamic volume. GPC/SEC columns are packed with very small porous beads. The smaller molecules can enter the pores more easily and therefore spend more time in these pores, eluting last. Conversely, larger molecules spend little if any time in the pores and are eluted quickly. The GPC columns are filled with a microporous packing material and gel, hence the name gel permeation.

Ion Exchange Chromatography (IEX)

Ion exchange chromatography (IEX), today often referred to simply as ion chromatography (IC), separates molecules based on the respective charged groups on the surface of a protein. IC is used for the separation or purification of proteins and antibodies. However, it is also popular for oligonucleotides, sugar or RNA molecules, etc. The main advantages of IC are speed, sensitivity, selectivity and simultaneity. It should be noted that, depending on the separation column, only cations or anions can be separated.

The pH value, the concentration or the gradient are important aspects affecting the results of IEC.

The stationary phase usually consists of a polymer resin such as polystyrene, cellulose, cross-linked polyacrylamide or polydextran. A distinction is made between strong and weak anion or cation exchangers.
