Emerson has introduced a hybrid continuous gas analyser designed to support regulatory compliance and emissions control across a wide range of industrial applications.
The Rosemount QX1000 Continuous Gas Analyzer, developed by Emerson, combines paramagnetic detection for oxygen (O₂) measurement with quantum cascade laser direct absorption spectroscopy for other gases within a single device.
Hybrid continuous gas analyser for CEMS applications
The hybrid continuous gas analyser is designed primarily for use in continuous emissions monitoring systems (CEMS), which are required at many industrial facilities where gases are emitted to atmosphere. Typical sectors include chemical processing, oil and gas, power generation, pulp and paper, refining, and water and wastewater treatment.
By integrating laser-based and paramagnetic technologies, the analyser aims to deliver high selectivity and measurement accuracy across complex gas streams. Standard configurations support monitoring of CO, CO₂, O₂, NO, NO₂ and SO₂, with options for additional gases such as CH₄ and N₂O.
Cold/dry sample conditioning approach
The system uses a cold/dry technology approach, incorporating a sample conditioning system that transports extracted process gas through a thermoelectric chiller. Cooling the gas to approximately 4°C removes most moisture through condensation before analysis.
The analyser can be integrated into existing plant infrastructure or supplied as part of a broader Emerson system solution, including sample conditioning components.
Focus on reliability and lifecycle cost
According to Emerson, the QX1000 has been engineered to minimise maintenance requirements by eliminating moving parts commonly associated with higher failure rates. Reduced consumables and simplified maintenance routines are intended to lower total cost of ownership, particularly in CEMS applications where system downtime can lead to compliance risks and financial penalties.
“A major differentiator of the QX1000 is the integration of multiple advanced technologies within a single device, providing the best-fit solution for each measurement need,” said Beth Livingstone, global product manager, process gas, Emerson. “The QX1000 is not only the first of its kind, but it also marks the beginning of a portfolio of analysers designed to set new gas analysis standards.”
