GC112A-6 Gas Chromatograph

Sample injector with Double Packed Column + Sample injector with special-purpose capillary column, having the blowing-up function of diaphragm and the shunting regulation with back pressure valves + Double FID
Flexible Sample Injector System Satisfying Various Analysis Requirements 

The instrument can install up to three sample injectors at the same time. According to the analysis requirements, the instrument can choose the best combination of the sample injectors, each unit of such combination can control the temperature independently, and the assembly/disassembly of these sample injectors may be very simple. 

Sample Injector with Mono Packed Column/Double Packed Columns
The device can realize the sample injection method that the sample is entered from the head of the packed column, which enables it to be widely used by various kinds of chromatographic columns and increases 6-way valves to make gas analysis. To adopt some connector pieces in the sample injector with packed column enables the instrument to finish 0.53 wide aperture capillary column analyses simply and conveniently. 

2 Kinds of Sample Injector Systems with Capillary Columns Suitable for Various Specifications of Capillary Columns 
a)     Sample injector with special-purpose capillary column, having the blowing-up function of diaphragm and the shunting regulation with back pressure valves. 
b)     Shunting/non-shunting sample injector with special-purpose capillary column is furnished with independent carrier gas circuit and make-up gas, has the flowing-up function of diaphragm and the shunting regulation with back pressure valves. The cleaning solenoid value at the entry realizes the shunting/non-shunting sample handling of capillary columns through setting the timing programe.
