Rosemount™ CT5800 Flameproof Process Gas Analyzer

The Rosemount CT5800 continuous gas analyzer is the first Quantum Cascade Laser (QCL) analyzer designed for industrial process applications requiring Class I, Division 2 hazardous area certification.

Built within a flameproof enclosure, the CT5800 unique cell design enables high accuracy measurement of concentrations of impurities down to low ppm levels in the gas streams, and is ideal for Hydrogen purity, Nitrogen purity and Ethylene purity applications. With up to six laser modules housed inside the same enclosure, the CT5800 analyzer can measure up to twelve components simultaneously, greatly reducing the need for multiple analyzers.

+ Multi-component QCL Analyzer
  • Measure up to twelve gases simultaneously

  • Excellent linearity of response and repeatability
  • Low long term drift minimizes calibration intervals
  • Low maintenance and low lifetime costs
  • Continuous health diagnostic reporting
  • Embedded ARM processor for fully autonomous operation
  • Intuitive simple front panel user interface allows access to all instrument functions
+ Field serviceable and field configurable
  • Interchangeable modular configuration for up to six lasers
+ Hazardous certification
  • Europe: ATEX II 2G Ex d IIB+H2 T4
    • IECEx: IECEx SIR 17.0026X ATEX: Sira 17ATEX1094X
  • North America: Class I, Division 2, groups B, C, D
+ Engineered Sample Handling Systems
  • A process gas analyzer is only as good as the quality of the sample it measures, which is why Emerson provides custom-engineered sample handling systems designed to the meet the application’s specifications and is rigorously tested before it ships to the customer.
+ Typical features include

Process gas stream purity applications including:

  • Hydrogen purity
  • Nitrogen purity
  • Ethylene purity
  • Natural Gas purity

Rosemount™ CT5100 Continuous Gas Analyzer - QCL Technology

 

QCL TECHNOLOGY

Emerson’s Quantum Cascade Laser technology offers fast, high resolution spectroscopy to detect and identify a range of molecules in the mid-infrared wavelength range. Coupled with Tunable Diode Laser (TDL) spectroscopy, a single instrument is now able to broaden insight and monitor both the near and mid-infrared range of spectroscopic light.

Rosemount™ CT5100 Continuous Gas Analyzer - Patent Chirp Technique

 

PATENTED CHIRP TECHNIQUE

When power is applied to the analyzer, the QCL heats up and as the temperature rises, laser wavelengths begin to increase. The QCL then sweeps the wavelength frequencies to detect each component of interest before cooling the device to its original temperature. This patented laser chirp process occurs in under one microsecond, enabling thousands of spectra to be recorded each second.

 

SIMULTANEOUS GAS ANALYSIS

QCL analyzers can be configured to have up to six high-resolution laser modules and measure up to twelve unique components simultaneously.

1. Optical bench base plate – superior rigidity for continuous, high accuracy measurement that is immune to vibration and temperature changes.

2. Smart laser modules – unique and sequenced laser chirp for fast, multi-component measurement.

3. Optical path mirrors – direct light, rigid connection to base plate to ensure alignment.

4. Flow Cell - designed to extend optical path length for greater resolution of low component (or analyte) concentrations.

5. Detector - ultrafast detection of emitted light.

Rosemount™ CT5100 Continuous Gas Analyzer - Detection-Analysis

 

ANALYSIS COMPONENT DETECTION ANALYSIS

Combining QCL and TDL techonologies into a single analyzer provides unmatched measurement performance and accuracy for process gas analysis. The narrow line width allows scanning of individual peaks of identified components with minimum interference and without filtration, reference cells, or chemometric manipulations.

 

ADVANCED QCL LASER MODULE

One of QCL’s major advantages is its laser module. Rugged and compact, the packaged laser modules can be removed and easily serviced or replaced as needed. Attached securely to the analyzer’s optical bench, each module is preconfigured to detect up to two components simultaneously with no field alignment required.
