Gas Sampling System

The sampling and conditioning train that determines whether the analyzer receives a representative gas sample.

Application: Air Emission Monitoring
Sector: Cement, Chemicals, Petrochemicals, Power generation (PLN, coal-fired)
Specifications: Configured for site conditions. Datasheet available on request.

Gas sampling system panel with pump, filters, and flow meters

Operational use cases

Replacing or upgrading the sample line of a running CEMS.
Unstable readings caused by condensation, leaks, or clogged filters.
Integrating a new analyzer with existing sampling points.

Measurement principle

An analyzer is only as accurate as the sample it receives. A gas sampling system takes the sample at the measurement point, retains particles, keeps the sample free of condensation along the line, and prepares it for the analyzer.

Many CEMS data problems start in the sample line, not in the analyzer. That is why we treat the sample line as equally important.
