Multi-component gas analyzer NDIR sensor O2 CH4 CO CO2 H2 methane gas analyser Hydrogen gas analyser

Here are some key details about multi-component gas analyzers:

- Used to measure multiple gases in a sample mixture using various sensor technologies. Allows cost-effective continuous monitoring.
- Typical gases that can be measured: O2, CO, CO2, CH4, CxHy hydrocarbons, H2S, NOx, SO2, N2, moisture, etc.
- Main analytical techniques: Non-dispersive infrared (NDIR) for CO, CO2, hydrocarbons; Paramagnetic for O2; Electrochemical cells for toxic gases; Thermal conductivity for inerts.
- May combine several modules/technologies into one analyzer unit. Each component has its own sensor, signal conditioning, and calibration.
- Sample handling system conditions and transports the sample gas to the sensors. Requires particulate and moisture removal.
- Displays and records concentrations of each gas on screen and software. Alarm relays for concentration thresholds.
- Used in applications like combustion flues, emissions monitoring, chemical/petrochemical processes, heat treating furnaces, gas leakage detection.
- Benefits include lower cost than multiple single-component analyzers, reduced maintenance, continuous multi-component data for better process control.
- Regular calibration with certified span gas mixtures required to maintain measurement accuracy.
- Key specifications are number of gases measured, measurement ranges, accuracy, linearity, repeatability, drift, response time.
- Overall, multi-component analyzers provide an efficient and compact solution for multi-gas monitoring needs across industries.

Process gas analyzer is an important tool in process safety and quality control. It helps to monitor and optimize the chemical composition of process gases. The gas analyzer market is segmented by type, technology, application, and geography.

Our gas analyzers high-stability infrared detector and TDL technology for the simultaneous measurement of CO, CO2, and CH4. These gases are suitable for challenging applications such as syngas and gasification atmospheres. In addition, analyzers may use a compensated thermal conductivity cell for H2. Electrochemical O2 sensors may also measure percent levels of oxygen in the sample gas stream.
