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 (the relative amounts of such components can also be determined). In some situations, GC may help in identifying a compound. In preparative chromatography, GC can be used to prepare pure compounds from a mixture
Gas chromatography (GC) is widely used in power sector, corporation that produce oil immersed electrical apparatus--- Transformer factory, wire cannula factory and enterprises—power plant, power supply bureau , other units for gas analyzing like chemical processing of coal and Bruckhausen.
Instrument introduction
GC9790 series gas chromatograph is one kind of universal type,high performance multi-purpose series chromatograph instrument, may according to need to choose many kinds of detector combinations, satisfies the ordinary laboratory,current production,conventional examination and microscale,trace amount analysis request. The internationalization production management idea and the production policy, have guaranteed each leaving the plant instrument's reliability,durability,easy Maintainability.
Features:
Six ways temperature control system, classical zero crossing pulse triggering control system, resists the electromagnetic interference enormously
May simultaneously carry on the temperature control to six objects, temperature by the keyboard setting,automatic control, unique many kinds of excessively warm protection function, assured instrument's use security enormously. Because the zero crossing pulse triggering control system, reduced the electrical network enormously or periphery spatial electromagnetic interference.
Friendly man-machine conversation interface, easy to understand, easy operation
Uses large screen with backlight lattice LCD to demonstrate that the information content is bigger, hommization keyboard design, guaranteed the easy operation.
Many kinds of detector flexible combination configuration, application is more widespread
Can install TCD,FID,ECD,FPD,NPD etc detector for the customer arbitrary selection and combination, guaranteed the widespread application.
Intelligent breakdown self-checking and alarm function
Real-time feedback instrument breakdown information, convenient user retrieval breakdown, guaranteed the instrument easy to maintain
Technical specification:
Temperature control parameter
Unique double air flue cold hot alternate system，guaranteed warming and cooling speed. Special material box body heat preservation interlayer，had guaranteed the instrument control warm stability.
Temperature:RT+8C～399C(1C increment)
Temperature programming:6 ramps
