The Rosemount QX1400 uses the same hybrid laser-based and paramagnetic measurement technologies as the Rosemount QX1000 Continuous Gas Analyzer, but it comes with certifications allowing its use in hazardous areas.
For Europe, these certifications include ATEX II 2G Ex d IIB H2 T4 and R.O.W: IECEx Ex db IIB+H2 T4 Gb. North American certification, expected by the end of 2026, will be for Class 1, Division 2, Groups B, C, D, T4.
This hybrid integration of different technologies and a modular approach provide a flexible, single-system solution tailored to diverse application needs. The Rosemount QX1400’s design with low maintenance requirements also reduces lifecycle cost and downtime.
Safety Certifications
Safety certifications enable the Rosemount QX1400 to end up installed in certain hazardous areas without the need for protective measures, such as installation in explosion-proof or purged enclosures.
This capability reduces the cost and complexity of design and installation to maximize uptime and enhance safety. Additionally, in some applications, it can be installed closer to the sampling point to reduce cost and provide more accurate measurements. Applications that often require gas analysis in hazardous areas include CEMS, liquified natural gas (LNG) facilities, chemical and petrochemical plants, and many others.
“Gas analysis applications should not require users to choose between the measurement technology they need and the hazardous-area installation their site demands,” said Dr. Beth Livingstone, global product manager, process gas with Emerson’s measurement instrumentation business. “The Rosemount QX1400 brings complementary technologies together in one certified platform to simplify system design, while providing the measurements required for critical emissions, quality and purity applications.”

Leveraging the intrinsic high selectivity of laser-based measurement, this new analyzer provides precise monitoring of complex gas streams while delivering continuous, real-time data.
Off the shelf, it supports multi-component measurement of key regulatory gases, including CO, CO₂, O2, NO, NO₂, and SO₂, with different configurations typically offering detection of one to four gases. Meanwhile, measurement of additional gases, such as CH₄ and N₂O, is also available.
