High performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.

The new Anion column line from Hamilton is designed to meet the special requirements of anion analysis. The unique design of the highly cross-linked porous packing material and the strong covalent bonded surface chemistry ensure excellent durability and high separation efficiency over the entire column lifetime even under harsh conditions. The columns are designed to be used with carbonate-bicarbonate buffer in any concentrat…
Ascentis Express HPLC columns, through the use of Fused-Core® particle technology, can provide you with both the high speed and high efficiencies of sub-2 μm particles while maintaining lower backpressures. The combination of high efficiency and low backpressure benefits UPLC® (or other ultra high pressure system) users, as well as conventional HPLC users. Column Details: Mode of chromatography: Hydrophilic interaction…
ResiPore columns are the ideal choice for the analysis of resins, and condensation polymers with complex molecular weight distributions that include oligomer content. By combining a low 3 µm particle size and high pore volume, high efficiency ResiPore columns offer maximum resolution of these intermediate molecular weight polymers. Features: Efficient separation of complex molecular weight distributions Reveals oligome…
Cogent Bidentate C8™ HPLC Columns are manufactured with TYPE-C™ silica (silica hydride) and a straight chain C8 hydrocarbon bonded directly to the Silica Hydride surface with two separate points of attachment. The manufacturing of the Silica makes these columns virtually indestructible.
The BLC-30 from Buck Scientific offers analytical versatility at an excellent price. The BLC-30 HPLC is an isocratic system with a variable wavelength detector. The BLC-30 Series Analytical HPLC systems use a high-quality, precision monochromator based spectrophotometer for a full range of wavelengths from 190-800nm for selective analyses integrated into a complete LC package. The 20-series is easily upgraded to a gradient Sy…

Filter Fluorescence Detector For HPLC - Customer to select wavelength. The new DFL-10 HPLC Fluorescence detector provides the sensitivity and the specificity of fluorescence detection at a price consistent with most low cost UV detectors.The DFL-10 can be configured with a choice of lamps covering the UV and Visible regions of the spectrum. Choices include Deuterium (at an additional cost with a recommended expanded range pho…
Fraction Collector - 116 tube capacity for 10 to 16 mm tubes. Our fraction collector can be operated as a simple fraction collector, where each fraction is the same size and the fraction size is set in terms of time, drops, or external events (like counts from a pump). A simple command entered from the membrane keypad enables the internal peak detector. This allows you to collect only those peaks of interest from the chromato…
We have found the Schambeck Refractive Index Detector to work very well with our HPLCs. Our fraction collector can be operated as a simple fraction collector, where each fraction is the same size and the fraction size is set in terms of time, drops, or external events (like counts from a pump). A simple command entered from the membrane keypad enables the internal peak detector. This allows you to collect only those peaks of…
