A gas analysis system is a solution that detects and measures the concentration of various gases within a sample. It typically works by drawing in a sample of gas, passing it through sensors that use techniques like infrared absorption, mass spectrometry, or chemical reactions to identify and quantify the gases present. The results are then displayed or recorded for monitoring, analysis, or control purposes.​

To choose the right gas analyzer for your specific application, consider the following factors:​

  • Type of Gases: Identify which gases you need to measure.​

  • Measurement Range: Ensure the analyzer can detect the concentration ranges required.​

  • Accuracy and Precision: Check the specifications for measurement accuracy.​

  • Response Time: Consider how quickly you need results.​

  • Environmental Conditions: Make sure the analyzer can operate under your specific environmental conditions, such as temperature and humidity.​

  • Compliance and Standards: Verify if it meets any relevant industry standards or regulations.​

  • Maintenance and Calibration: Consider the ease of maintenance and calibration requirements.​

  • Budget Constraints: Factor in the cost and your budget.​

By evaluating these criteria, you can select a gas analyzer that best fits your application's needs.​

Emerson Rosemount gas analyzers can detect and measure a variety of gases including carbon monoxide (CO), oxygen (O2), carbon dioxide (CO2), nitrous oxide (N2O), sulfur dioxide (SO2), ethylene (C2H4), nitrogen (N2), helium (He), hydrogen (H2), and trace moisture (H2O).

The Rosemount 470XA Gas Chromatograph is a compact, economical, and reliable solution designed to simplify natural gas analysis in natural gas applications. It provides accurate C6+ BTU/CV measurement that is traceable to international standards.

Emerson’s Rosemount QCL/TDL-based Continuous Emissions Monitoring Solutions (CEMS) provide a reliable, field-proven solution for accurately monitoring up to ten critical gas components and pollutants to help operators meet environmental compliance requirements and optimize process performance.​

By combining Quantum Cascade Laser (QCL) and Tunable Diode Laser (TDL) technologies, these hybrid, multi-component systems deliver comprehensive gas analysis across both the near- and mid-infrared spectral ranges. This enables operators to detect a wide range of emissions with unmatched precision.​

Key benefits include:​

  • High Accuracy & Speed – Patented laser chirp technology captures thousands of precise measurements, ensuring repeatable, real-time emissions monitoring.​

  • Simplified Operations – Reduced consumables and minimal calibration needs lower costs and make maintenance easier.​

  • Automated Reliability – Built-in validation and calibration capabilities ensure consistent measurement performance without manual intervention.​

  • High-Temperature Capability – Handles sample temperatures up to 374 °F (190 °C) to maintain hot/wet samples above the acid dew point for more accurate readings.​

  • Compliance Confidence – Supports emissions monitoring needs at the global, national, state, and local levels.​

With Emerson’s Rosemount technologies, operators gain the speed, accuracy, and reliability needed to confidently meet evolving environmental regulations while improving process efficiency.​
