Specialty Chromatographs and Chromatography Accessories

Specialty chromatographs and chromatography accessories are specialized or proprietary products related to chromatography and chromatography instruments. Chromatography is an analytical technique used in the chemical separation of mixtures and substances. It depends on the differential distribution of a solute between mobile and stationary phases. As the solute passes through the stationary phase, each constituent of the mixture separates at different speeds. These constituents can then be analyzed with chromatography instruments such as chromatograms, chromatographs, and ultra low pressure calibration devices. The proper selection of specialty chromatographs and accessories requires an analysis of product specifications and capabilities. Typically, a specialty chromatograph is used to perform chromatographic separation and to produce a specialty chromatogram, the pattern of bands of substances separated by a chromatograph column. Suppliers of specialty chromatographs and accessories are located across the United States and around the world.

Specialty chromatographs and chromatography accessories are used with many different types of chromatography and chromatography instruments. Common chromatographic techniques include thin layer chromatography (TL), high performance thin layer chromatography (HPTLC), high pressure liquid chromatography (HPLC), gas chromatography (GC), mass spectrometry (MS), and gas liquid chromatography (GLC). A high pressure liquid chromatograph (HPLC) uses a liquid mobile phase to separate the components of a mixture. The components are dissolved in a solvent and forced to flow through a chromatographic column under high pressure. Medium pressure liquid chromatography is used with substances that cannot be resolved chromatographically at atmospheric pressures. Gas chromatographs (GC) consist of a flowing mobile phase, an injection port, a separation column containing the separation phase, and a detector. For the detector, a gas chromatograph can use thermal conductivity, flame ionization, atomic emission, electron capture, photo ionization, flame photometric, chemiluminescence spectroscopy, and nitrogen phosphorous.

Specialty chromatographs and chromatography accessories are used in a variety of applications and industries. Examples include biochemistry, food and beverage processing, and the manufacture of pharmaceutical products. Specialty chromatographs and accessories are also used in the production of perfumes and the separation of chemical solvents.
