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
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.
