LAS 5000XD

In-Situ cross duct laser (TDLS) gas analyser

The In-Situ TDLS gas analyzer has been designed for meeting the requirements of a large range of CEMS and Process applications.

 

LAS 5000XD uses Tunable Diode Laser Spectroscopy (TDLS) and comes in various models for measuring parameters such as NH3 + H2O, HF, CO + CO2, O2, HCl + H2O, etc.

 

It combines robustness, fast response time (1 s) and high accuracy measurement in harsh environments (ready for Ex Zone II).

 

Key operator benefits of LAS 5000XD In-Situ laser gas analyser:

 

  • No sampling system needed
  • No gas temperature influence
  • Gas matrix interference free
  • Calibration free measurement

 

Thanks to ClearPath, interference of relative humidity, O2 or CO2 is removed in purging areas.

FEATURES AND BENEFITS

  • New embedded ClearPath functionality
  • Highly sensitive and selective measurement
  • High signal-to-noise ratio
  • No measurement drift
  • Response time 1 s
  • Large dynamic range from ppm to %
  • Real-time communication between Transmitter (Tx) and Receiver (Rx)
  • Robust, ready for Ex Zone II (certification to come)
  • Interference of relative humidity, O2 or CO2 is removed in purging areas.
  • No need for N2 or dry air purge
  • High accuracy of O2 measurement
  • High accuracy of H2O measurement
  • High accuracy of CO2 measurement
  • Low maintenance and cost of ownership
  • No need for N2 or dry air purge: Oil & dust free air instrument is enough
  • Process optimisation leading to reduction of operating costs
 
 

MAIN APPLICATIONS

  • Ammonia slip control (DeNox)
  • Process and combustion control
  • HF emission control in aluminum plant
  • HCl/SO2 abatement control
  • Ethylene cracking furnace control
  • HCl level in semiconductor production
  • Ammonia concentration control in pet food, fertiliser plants, etc.
