Wuhan Wugao Electric Measurement Co., Ltd

WDCD-9560 Power dedicated gas chromatograph

The gas chromatograph is a computer-controlled multi-purpose high-performance series of gas chromatographs. The instrument has a full microcomputer automatic control system, which can not only control multiple temperatures (column oven, sampler, multiple detectors, auxiliary, etc.) at the same time, but also control the attenuation and zero adjustment of the detector measurement circuit through key operation. , high stability and reliability.

1.3.2 Detector specifications

Hydrogen Flame Ionization Detector (FID)

Detection limit: Mt < 3 *10-12g/s (n-hexadecane);

Noise: <5*10-14A

Drift: <1*10-13A/30min

Linear range: > 106

Maximum Service Temperature: <450 Temperature

Thermal Conductivity Detector (TCD)             

Sensitivity: S > 3500mV ml/mg (n-hexadecane) (amplification 1, 2, 4, 8 times optional)

Noise: <10 uV

Baseline drift: <30 uv/30 min

Nickel Catalyst Converter

Temperature Control Range of Converter: 0-400 Temperature

Methanation conversion temperature: 350 ~380 C;

Temperature control mode: PT100 platinum resistance;

Converter tube size: N type 3 *160mm;

Heating power: 90W;

Methanation conversion: > 98%;

Note: The converter should be heated under the protection of hydrogen. This can protect Ni from oxidation, and oxidized Ni (NiO) can be reduced to Ni (NiO + H2 = Ni + H2O) by H2.
