Laser Gas Analyzer for TDLAS Gas Analyzer
Laser Gas Analyzer for Real-Time NH3 Monitoring
The laser gas analyzer from Instrava is designed for high-precision ammonia (NH₃) monitoring in industrial flue gas systems. Based on advanced TDLAS (Tunable Diode Laser Absorption Spectroscopy) technology, the analyzer provides fast, accurate, and interference-free measurement of ammonia concentrations in complex industrial environments.
This industrial laser gas analyzer can continuously measure NH₃ concentrations in flue gas, helping operators detect ammonia slip in denitrification systems (SCR/SNCR) and optimize emission control processes. The system features high sensitivity, fast response time, and stable long-term performance, ensuring reliable gas analysis even under high-temperature and high-dust conditions.
With real-time data output and compatibility with DCS control systems, the analyzer supports automated process adjustment and helps improve environmental compliance, operational safety, and energy efficiency.
Optical Analysis Description
Laser Gas Analysis for Industrial Emission Monitoring
The TDLAS laser gas analyzer is widely used in industries where accurate ammonia monitoring is critical for emission control and process optimization.
Typical application scenarios include:
-
Power plants – monitoring ammonia slip in SCR denitrification systems
-
Cement plants – flue gas emission monitoring
-
Metallurgical industries – industrial furnace gas analysis
-
Coking plants – flue gas pollution control
-
Chemical production facilities – ammonia concentration monitoring
-
Environmental monitoring projects – industrial emission compliance
By providing real-time NH₃ concentration data, the analyzer helps operators optimize denitrification efficiency, reduce reagent consumption, and maintain environmental compliance standards.
Its robust design allows stable operation in industrial flue gas environments with high dust, high temperature, and fluctuating process conditions.
Advanced TDLAS Technology for High-Precision Gas Measurement
The Instrava laser gas analyzer uses Tunable Diode Laser Absorption Spectroscopy (TDLAS) to achieve highly selective and accurate ammonia measurement.
Key system advantages include:
-
Laser-based gas detection technology with strong anti-interference capability
-
Fast response time (T90 ≤ 15 seconds) for real-time monitoring
-
High sensitivity measurement down to ppm levels
-
Stable long-term performance with service life exceeding 6 years
-
Automatic integration with industrial control systems
Unlike traditional gas sensors, TDLAS analyzers measure gas concentration through optical absorption, which minimizes cross-gas interference and ensures high measurement accuracy even in complex flue gas mixtures.
The analyzer can be easily connected to DCS or process control systems, enabling automated control strategies for industrial emission reduction.
