High sensitivity thermal conductivity gas chromatograph

The GC-9560-FT hydrogen flame thermal conductivity gas chromatograph uses dual injection and one instrument to achieve full analysis of inorganic impurities and hydrocarbon impurities in industrial grade gases. The detector adopts high-sensitivity hydrogen flame detector and thermal conductivity pool detector, and is equipped with an efficient conversion furnace to ensure high detection limit:

1、 Technical indicators

1. Detection limit: (using ultra pure hydrogen (99.9999%) as carrier gas)

2. Overall noise ≤ 5UV

• Baseline drift:<100UV/30min

• 1ml injection volume, peak height of 1ppmN2>15UV

• 3ml injection volume, peak height of 1ppmN2>50UV

3. System configuration:

• GC-9560 gas chromatograph 1 set

• 1 set of FID detector

• 1 set of TCD detector

• 1 set of conversion furnace

• 1 set of chromatography workstation

• 2、 Technical features:

1. The pipeline adopts imported materials and is hard sealed, ensuring no dead volume, adsorption or diffusion in the system to ensure the sensitivity and accuracy of thermal conductivity;
2. The control of the air path adopts a rear mounted control to avoid air infiltration from the header into the analyzed sample;
3. The sample can achieve baseline separation;
4. The tail of the valve injection system is equipped with a rotor flowmeter and a needle valve to control the injection flow rate and ensure the repeatability of the injection volume.
