Gas Chromatography (GC) Systems

 

Gas chromatography better known as GC, is a great analytical tool used by chemists to analyze compounds by separating them in the vapor phase without decomposition. This analytical chemistry instrument, the Gas Chromatograph (also known as aerograph or gas separators) can be used to test the purity of a particular substance, or for separating the different components of a mixture . In some instances, GC may be used to identify a compound. In preparative chromatography, GC can be used to prepare pure compounds from a mixture.

New and Used GC Systems from Top Manufacturers

Hewlett Packard ( HP ), Perkin Elmer (PE), Shimadzu, Agilent, Varian, Thermo are preferred manufacturers and have great brand awareness. Common detectors used on GC instruments are: Thermal Conductivity detector ( TCD ), Flame Ionization detector ( FID ), Electron capture detector ( ECD ), Hall electrolytic conductivity detector ( ElCD ), and Photo-ionization detector ( PID ). Integrator’s were used for many years but computers are used to control, record and interpret the data. Familiar software names are Chemstation, TurboChrom, Clarity are just a few.   

Gas-Liquid Chromatography

Gas chromatography is similar to column chromatography as well as other forms of chromatography, such as HPLC and TLC. In GC chromatography, the compound separation process in a mixture is carried out between a liquid stationary phase and a gas mobile phase, (in column chromatography the stationary phase is a solid and the mobile phase is a liquid). "Gas–liquid chromatography" also features a temperature oven controlled column through which the gas phase passes whereas column chromatography does not usually offer temperature control.

HP Gas Chromatograph Model 5890 PID ELCD Dectector

    Price: $2,999.00    POD Price: $999.00    

Hewlett Packard 5890 Series II GC PID Detector

Hewlett Packard Gas Chromatograph Model 5890 Series II, with PID / ELCD Detector. This combination detector couples a Photo ionization Detector with a Electrolytic Conductivity Detector. With these detectors in tandem, simultaneous detection of aromatic and halogen compounds is possible, eliminating the need for two separate analysis. Its unique design eliminates transfer lines and uses only one detector port. Both detectors can be used independently, if desired.
