CAI

CAI FID analyzers rely on the Flame Ionization Detection principle to measure the total concentration of hydrocarbons in a gas sample. The gas sample becomes ionized in the flame and the electrostatic field causes the charged particles to migrate, creating a small current that is measured by the amplifier. The current is directly proportional to the amount of hydrocarbon in the sample. The 700 MHFID model measures Total Hydrocarbon and provides a means of differentiating between Methane and non-Methane hydrocarbons.

S&V CAI

CAI FID analyzers can measure THC or CH4 in ppm or percent levels. They are ideal for applications such as:

S&V CAI 

- VOC abatement/scrubber efficiency
- Combustion engine testing
- EPA Method 25A compliance monitoring
- Continuous emission monitoring (CEMs)
- Vehicle emissions
- Fermentation monitoring
- Carbon bed breakthrough detection
- Process gas analysis
