Technology Comparison

ItemsCombustion based CV AnalyzersFPI's LGA-C300
Key componentAutomatic ignition device, is   prone to be disturbed by gas flow, pressure and gas source.Spectrometer based,on-line and   continuous.
Calibration gasGas proportion dependent,   complex and less accurate.Standard cylinder gas.
Reliability5 steps: sampling, ignition,   combustion,heat exchange and vent, more moving parts.3 steps: sampling, measure and   vent, less moving parts.
SafetyOpen flameNo flame, no chemical reaction.
Response timeSlow. Limited by combustion and   heat exchange
   
≤21s
Consuming partsPressure regulator, igniter,   heat exchanger,etc.No consuming parts.
OutputCalorific Value and Wobbe   Index.No indication of gas composition changing.Calorific Value and CO,CH4,H2   concentration,real quantitative detection.
