Emerson Rosemount QX1000 continuous gas analyser

Emerson has released its Rosemount QX1000 continuous gas analyser, suitable for use in continuous emissions monitoring systems (CEMS).

The QX1000 uses paramagnetic detection for O₂ and quantum cascade laser direct absorption spectroscopy for all other gases to meet stringent performance requirements. This integration of different technologies and a modular approach provide a flexible, single-system solution tailored to diverse application needs.

The analyser’s robust design with low maintenance requirements also reduces lifecycle cost and downtime.

It uses cold/dry technology, with a sample conditioning system transporting gas extracted from the process to the analyser through a thermoelectric chiller to reduce the temperature to about 4°C, so most moisture condenses and drops out.

Users can easily integrate the analyser into existing plant infrastructure, or it can be provided as part of an integrated Emerson system solution, including the sample conditioning system.

Measurements made by the analyser are suitable for CEMS applications due to its high selectivity and accuracy.

Leveraging the intrinsic high selectivity of laser-based measurement, the analyser provides precise monitoring of complex gas streams while delivering continuous, real-time data.

Off the shelf, it supports measurement of key regulatory gases, including CO, CO₂, O₂, NO, NO₂ and SO₂, with different configurations typically offering detection of one to four gases. Measurement of additional gases, such as CH₄ and N₂O, is also available.
