Technology Comparison
| Items | Combustion based CV Analyzers | FPI’s LGA-C300 |
| Key component | Automatic ignition device, is prone to be disturbed by gas flow, pressure and gas source. | Spectrometer based,on-line and continuous. |
| Calibration gas | Gas proportion dependent, complex and less accurate. | Standard cylinder gas. |
| Reliability | 5 steps: sampling, ignition, combustion,heat exchange and vent, more moving parts. | 3 steps: sampling, measure and vent, less moving parts. |
| Safety | Open flame | No flame, no chemical reaction. |
| Response time | Slow. Limited by combustion and heat exchange | ≤21s |
| Consuming parts | Pressure regulator, igniter, heat exchanger,etc. | No consuming parts. |
| Output | Calorific Value and Wobbe Index.No indication of gas composition changing. | Calorific Value and CO,CH4,H2 concentration,real quantitative detection. |
