LH-QTSEY轻烃色谱仪+自动进样 ( Light Hydrocarbon Chromatograph With Rotating Disk Autosampler )

Light Hydrocarbon Chromatograph With Rotating Disk Autosampler(LH-QTSEY VI)

1)Product principle

Light hydrocarbon chromatograph is a special instrument used in geological logging. It can analyze light hydrocarbon of natural gas, crude oil and rock, and get concentration or relative content of 103 monomer hydrocarbons before C9. It's mainly used for the evaluation of the oil-water layer, the reservoirs water flooded degree and washing degree in later period of oilfield development.

LH-QTSEY VI is a new generation of high-performance intelligent network light hydrocarbon chromatograph. Compared with the traditional instrument, it has five advantages: the fast cooling oven, high detection sensitivity, dedicated workstation software, 　computer control and networked remote supervision.

Rotating disk autosampler is specially developed for light hydrocarbon analysis, which can improve the automation degree of the process. It uses the sophisticated electronic control unit, to replace the traditional manual mode, which implements multiple samples analysis automatically and continuously, eliminates the human error, improve the working efficiency, analysis accuracy and repeatability.

LH-QTSEY VI light hydrocarbon chromatograph achieved connection between the instrument and autosampler, which can automatic quantitative sample analysis. The instrument provides more comprehensive information for oil and gas layers' estimation, and it is the essential equipment for finding oil-gas layer and evaluating reservoirs in the process of oil exploration logging.
