Introduction: The GC-LTA-II online hydrocarbon analyzer can analyze the trace hydrocarbons in the air separation plant and monitor the content changes of the explosive components, thereby providing important reference data for the safe operation of the main condenser of the air separation plant . It can also be used as a process control instrument for detecting hydrocarbons in the petrochemical, steel and gas industries. Features: 1. It continuously monitors samples of the gas to be measured. 2. Automatic timing, sampling, analysis, good separation and analysis effect, reliable data automatic analysis instrument. 3. Free switching between automatic and manual injection can be achieved to obtain more reliable data. 4. The instrument is easy to operate, and the injection and sampling time can be set arbitrarily. 5. Measurement objects: trace hydrocarbon content in main cooling liquid oxygen, liquid oxygen in storage tank and air. 6. If the customer needs the monitoring data, it can be uploaded to the operation interface of the main control room of the air separation through 4~20MA; 7. Supporting cabinet and necessary pre-processing system; 8. Comply with the corresponding national standards. 9. Instead of a mechanical valve, an electronic pressure and flow control system (EPC) is used for control. 10. The display and control system (computer) are combined with the analyzer host to realize an intelligent and concise modern operation mode. Technical parameter: Technical indicators Boot stability time: <1 hour Temperature control accuracy: ≤±0.1℃ The stability of the normal operation of the instrument: Baseline noise: < 0.5×10-13A Baseline drift: < 1×10-13A/30min Quantitative repeatability (in terms of acetylene): RSD≤3% Oven temperature Temperature control range: room temperature + 10 ~ 300 ℃ Temperature control accuracy: ±0.1℃ Flame Ionization Detector (FID) Temperature control range: room temperature + 10 ~ 300 ℃ Temperature control accuracy: ±0.1℃ Baseline noise: ≤0.05mv Baseline drift: ≤0.2/30min Minimum detection concentration: 0.01ppm (calculated as acetylene) Intelligent Control System (EPC) Range: 0～100Psi (pressure) 0～1000mL/min (flow rate) Resolution: 0.01Psi (pressure) 0.01 mL/min (flow) Instrument working environment Injection pressure: <0.2Mpa Allowable use temperature: 5~50℃ Allowable relative humidity: 5~85% Power supply: 220V±10%, 50 Hz10%
