Overview

GC7890 online non methane total hydrocarbon detection analyzer GC7890 online non methane total hydrocarbon detection and analysis gas chromatograph adopts the design concept of electrical separation, with a double-layer partition design, double column box, one with programmed temperature rise column box, and one with constant temperature column box. This allows for both programmed temperature rise and constant temperature, separating the circuit and gas circuit parts, avoiding the electromagnetic influence of the circuit on the detector, and making the instrument more accurate

GC7890 online non methane total hydrocarbon detection analyzer

GC7890 online non methane total hydrocarbon detection and analysis gas chromatographAdopting the design concept of electrical separation, a double-layer partition design is adopted, with dual column boxes, one with programmed temperature rise column box and one with constant temperature column box. This allows for both programmed temperature rise and constant temperature, separating the circuit and gas circuit parts, avoiding the electromagnetic influence of the circuit on the detector, and making the instrument more accurate. Can complete online monitoring of non methane total hydrocarbons, total hydrocarbons, VOCS， Benzene derivatives, CH4, etc.

10. Air quality - Determination of toluene, xylene, and styrene - Gas chromatographic method (GB/T14677-93)

Detection capability: methane, non methane total hydrocarbons, and total hydrocarbons

Range: Methane (0.1-10000) ppm; Non methane total hydrocarbons (0.05-10000) ppm (optional)

Detector: Hydrogen Flame Ionization Detector (FID)

Detection limit: ≤ 0.1 ppm (methane), 0.05 ppm (non methane total hydrocarbons)

Repeatability; RSD≤2%

Analysis cycle: Single channel ≤ 40S, dual channel ≤ 20s

Power supply: ＜ 300W, 220V AC/50Hz

Working environment: Temperature: (-10~50) ℃, Humidity: (10%~99%)

Gas source requirements: Carrier gas: high-purity nitrogen or zero grade air (≥ 99.999%);

Combustion gas: high-purity hydrogen gas (≥ 99.999%); Auxiliary gas: Zero grade air (hydrocarbons<20ppb)

Sample flow rate: 10-500ml/min

Data storage format: The data is stored on the hard drive of the industrial control computer, and will not be lost when powered off, making it easy to trace the data.

Multi channel switching function: capable of detecting 16 different VOCs samples (optional) online, preferably without this feature. Multi channel switching is solved by an integrated commercial solenoid valve. This place has a high failure rate of multi way valves.
