GC9890B Gas Chromatograph
Test the following gases:
Methane
Ethane
Ethylene
Propane
Acrylic
Isobutane
N-Butane
Butene
(customizable)
Equivalently adopts the core technology of American Agilent 5890 gas chromatograph, with green backlight LCD display function, intuitive and easy to operate.
The maximum operating temperature of each heating zone of the instrument is 450°C.
Dual-channel single-column compensation function, which compensates for baseline drift during temperature-programmed operation detection to ensure straight baseline and perfect chromatographic peak shape.
Self-inspection and fault diagnosis, power-off and gas-off protection.
The host comes with a two-way valve control system, which facilitates the automatic switching of valves.
It can be equipped with AS-200 high-efficiency liquid automatic sampler to realize unattended automatic sample injection analysis, improve analysis efficiency and reduce labor intensity.
The high-precision EPC (flow rate) system makes your flow rate clear at a glance, and the gas flow rate can be set accurately.
Ultra-low temperature control system can be installed in the column oven, the ultra-low temperature control can be as low as -80 degrees to meet your analysis needs of low boiling point substances.
Temperature control index
Column oven: 5°C to 450°C at room temperature, accuracy ±0.1°C
Sampler: room temperature 5ºC~450ºC, accuracy ±0.1ºC
Detector: 5ºC~450ºC at room temperature, accuracy ±0.1ºC
Column oven parameters
Temperature control range: 5°C to 450°C above room temperature with an accuracy of ±0.1°C
The order of temperature program: third order
Programmed heating rate: 0.1ºC~70ºC, increment 0.1ºC
Programmed heating holding time: 0~655Mins. (increment 1 Mins.)
The column box has a large volume and a rear-opening door design. It can cool down quickly after the programmed temperature rise. The cooling speed: it only takes 7 minutes to drop from 350°C to 60°C
Injection method:
Capillary split/splitless injection -Packed column head injection -Can be equipped with an unattended autosampler for sample injection.
Thermal Conductivity Detector (TCD)
