TECHNOLOGY COMPARISON
Items
Combustion based CV Analyzers
FPI's LGA-C300
CO、CH 4 Module
Key component
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
11
Automatic ignition device, is prone to be
disturbed by gas flow, pressure and gas source.
