ENVEA presents the new LAS 5000XD in-situ laser (TDLS) gas analyzer
November 02, 2022
The new TDLS (Tunable Diode Laser Spectroscopy) LAS 5000XD gas analyzer comes in various models for measuring an extensive range of parameters such as NH3 + H2O, HF, CO + CO2, O2, HCl + H2O, CO2 + H2O, etc.

It has been designed to offer robustness, fast response time (1 s) and high accuracy measurement in harsh environments (ready for Ex Zone II).
The analyzer is calibration free, doesn’t require a sampling system and provides a large and dynamic measurement range from ppm to %.

It offers real-time communication between Receiver and Transmitter units and an embedded web server. In addition, the LAS 5000 XD includes a specific feature for managing outside path interference. Indeed, thanks to ClearPath, interference of relative humidity, O2 or CO2 is removed from the purging areas. This guarantees high accuracy measurement of H2O, O2 and CO2. As a consequence, N2 and dry air purge are not needed

Operator’s benefits include low maintenance, process optimization and reduced total cost of ownership.

The instrument is adapted to a wide range of applications for CEMS and Process, such as:

  • Ammonia slip control (DeNox)
  • Combustion control
  • HF emission control in aluminum plant
  • HCL abatement control
  • Ethylene cracking furnace control
  • HCl level in semiconductor production
  • Ammonia concentration control in pet food and fertilizer plants, etc.

Examples of measuring ranges:
NH3 + H2O 0–10 ppm / 0–5000 ppm + 0–5 % / 0–40%
HF 0–3 ppm / 0–500 ppm
CO + H2O 0-50 ppm / 0-1% + 0-5% / 0-40%

The LAS 5000XD features a full package of optional accessories ensuring a smooth and efficient operation (Thermal Shield, weather protection covers, etc.).
