Instruments used to separate chemical mixtures, carried by liquids or gases, into components as a result of differential distribution of the solutes as they flow around or over a stationary liquid or solid phase.
Chromatography Categories
Gas Chromatographs
Gas chromatographs separate organic chemical mixtures according to physical properties.
GC Columns
Gas chromatography columns (GC columns) are of two types: packed and capillary. Solutes to be measured travel through the column at a rate primarily determined by their physical properties, and the temperature and composition of the column.
GC Detectors
Gas chromatography detectors (GC detectors) identify solutes as they exit the chromatographic column. A chromatogram is generated plotting the signal versus time.
High Performance Liquid Chromatographs (HPLC)
High performance liquid chromatographs (HPLC) use 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.
HPLC Columns
High performance liquid chromatography (HPLC) columns use a liquid mobile phase to separate the components of a mixture.
HPLC Detectors
High performance liquid chromatograph (HPLC) detectors pass a beam of light through a column effluent as the fluid passes through a low-volume flow cell. Variations in light intensity are recorded and a chromatograph is generated.
Instrument Calibration Services
Instrument calibration services test equipment and calibrate them to various standards.
