High Performance Liquid Chromatography is widely used in the analysis of Ethanol, ketone, Aldehyde and Etheric isolation analysis etc. The novel appearance, high reliability, stability and easy operation of the instrument make it the optimum choice for chemical laboratory. Its double beam monochromator and dual lens flow cell produce super elevation sensitivity. Further its original pressure feedback control system reduces the dead volume of the system to the largest extent.

Gas chromatography (GC), is a common type of chromatography used in analytic chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture. In some situations, GC may help in identifying a compound. In preparative chromatography, GC can be used to prepare pure compounds from a mixture. The important features are it has large LCD display, convenient to set parameter.

Gas Chromatography is carried out in a specially designed instrument. A very small amount of liquid mixture is injected into the instrument and is volatilized in a hot injection chamber. Then it is swept by a stream of inert carrier gas through a heated column which contains the stationary, high-boiling liquid. As the mixture travels through this column, its components go back and forth at different rates between the gas phase and dissolution in the high-boiling liquid, and thus separate into pure components.

Gas Chromatography is equipped with a huge array function and the GC is robust, flexible, and user-friendly. Its circular oven is designed to facilitate homogenous thermal distribution and temperature control, which has greatly improved the reproduction of analysis. Both detector and inlet are modular units. This standardization allows flexible assembly of GC system for various types of analysis in a simple way. The instrument can be equipped with different sampling devices and it can be used to analyze gas, liquid and solid samples.
