Gas Chromatograph For Gasoline Aromatics

Gas Chromatograph For Gasoline Aromatics
Product Detailed
Gas Chromatograph 1.Has the microcomputer temperature control system 2.Can be used in multidimensional chromatography analysis

  Gas Chromatograph

Introduction & Specifications :

GC112A Gas Chromatograph( gasoline aromatics chromatography )  

Main Features:

Equipment performance standards: GBl7930-1999 ‘ Car to unleaded petrol” , ASTMD3606-1996 ‘motor gasoline and aviation gasoline benzene and toluene content of the assay(GC)” Meet JB/T6224-1992 "Laboratory of Gas Chromatography" , JJG700-1990 "Gas Chromatography"


Microcomputer temperature control system,high accuracy of temperature control (better than: ±0.1 °C)

Control and operating parameters (including for detectors) set up by the keyboard. Self-diagnosis system, power-fail protection, file storage and call, limited temperature setting. Accurate display of setting and actual value of temperature control of each path, bridge current of TCD, sensitivity of FID, retention and analysis time.

Three sets of steady carrier gas flow control. Accurate and scaled type gas path control valves will provide a high repeatability and stability. Directly read flow value and the adjustment is convenience.

Thermostat flat six-way valve provided with options of automaticly switching six-way valve components by computer timely.

Auto-drop of temperature of column oven (auto-opening the door behind the oven) to a fast cooling.

High separation efficiency, good repeatability. High sensitivity, low noise and the time is short of stable equilibrium of Thermal Conductivity Detector (TCD)

Open-end computer system can apply RS-232 interface and FJ-2000 chromatogram workstation to achieve dual path communication control and data processing.

Large volume column (300x280x270) can hold several dedicated packed columns. Can be used in multidimensional chromatography analysis


Temperature control:

Temperature zones: column box, into the sample containers, thermal conductivity pool, six-way valve.

Temperature control range: 7°C-399°C of room temperature (increment by 1°C)Temperature accuracy: better than ± 0.1 °C (200 °C).

Thermal Conductivity Detector (TCD):


Sensitivity: S> (carrier gas: H2)

Baseline Noise: ≤ 20uV

Baseline drift: ≤30uV/h
