CMS-6000LNG storage and distribution station online chromatography analyzer
Introduction: CMS-6000 online calorific value analyzer can simultaneously detect LNG natural gas, CNG natural gas full component content, such as nitrogen, methane, carbon dioxide, ethane, propane and other natural gas parameters. The instrument implements the national standard for natural gas detection. Features: 1. Inlet flow, column carrier gas flow, detector gas flow, precise control A variety of injection ports can be equipped: packed column injection port (with septum purging, can be connected to large-diameter capillary column), split/splitless capillary injection port, programmed temperature cooling on-column injection port for volatile components in series Sample inlet (specially equipped with sample pretreatment devices such as headspace/purging and trapping/thermal desorption); 2. Industry-leading detector design Amplifying board with special ceramic treatment, always stable in wet season, automatic ignition, automatic protection function of hydrogen leakage, safe and reliable. 3. Precise control of programmed temperature rise and furnace temperature, accurate furnace temperature tracking design The internal control accuracy of the furnace is less than 0.01 °C; the temperature difference between the internal points is not more than 1 °C; rapid heating and cooling, the maximum temperature program heating rate is 120 °C/min; the equilibrium time is 10 seconds; the cooling time (300 °C to 50 °C) 6min; Absolutely controlled temperature accuracy (less than 0.3°C difference from actual temperature). 4. Fully imported valve configuration system Equipped with up to 8 valves (four-way valve, six-way valve, ten-way valve and liquid injection valve are optional); automatic control, sequence operation; zero leakage purge technology; long life of high-speed switching solenoid valve (1 million times, 10mS) ). 5. Independently heated small column box In the multi-column chromatography system, the operating temperature of different columns can be set separately, so as to achieve the best separation effect of each column; 6. Convenient realization of pneumatic cutting technology It can realize the multi-dimensional chromatography function to complete the separation and analysis of complex samples, and can realize the backflushing function of the chromatographic column to greatly save the analysis time and cycle; Technical parameter: column oven Temperature control range: room temperature +5℃~450℃; Temperature setting accuracy: 0.1℃ Program heating rate: 60℃/min Program ramp number: 8-step ramp program Rise rate: 0.1~120℃/min (increment 0.1℃) Maximum runtime 999.99 minutes heating zone 6 independent control heating zone control (excluding oven temperature control, two inlets, two detectors,; two auxiliary heating zones Auxiliary heating zone operating temperature: 300℃ Detector Hydrogen flame ionization detector FID Use temperature: 450℃ Detection limit: ≤2.5pgC/s [n-C16] Dynamic linear range: ≥107(±10%) Data collection frequency: 100Hz Compatible with packed and capillary columns Thermal Conductivity Cell Detector TCD: Use temperature: 400℃ Detection limit: <400pg propane/ml, helium Dynamic Linear Range: 105(±5%) Data collection frequency: 100Hz
