Analizador láser in situ de gases de proceso: medición cruzada en tiempo real sin muestreo
True In-Situ Gas Analysis — Measure Directly in the Process, Not After It
When milliseconds matter and process conditions are harsh, traditional extractive systems fall short.
En Instrava Curated In-situ Laser Process Gas Analyzer is built on advanced TDLAS (Tunable Diode Laser Absorption Spectroscopy) technology, enabling direct cross-stack gas measurement without sampling, conditioning, or delay.
✔ No gas extraction lines
✔ No sample conditioning systems
✔ No measurement lag
👉 This means real-time, accurate process insight exactly where it happens.
Con T90 ≤ 4 seconds, it delivers one of the fastest response times available for:
- Combustion optimization
- Oxygen control
- Emission monitoring
- Safety-critical process control
Análisis óptico Descripción
High Selectivity & Stability — No Cross-Interference in Complex Gas Streams
Unlike traditional gas analyzers, this system uses laser-based absorption spectroscopy, ensuring:
- High selectivity for target gases
- Zero cross-interference from background gases
- Stable performance even in dusty, high-temperature, high-moisture environments
Measured Gases:
- O₂ (combustion efficiency & safety)
- CO (incomplete combustion indicator)
- CO₂ (process & emission monitoring)
- CH₄ (fuel gas & leakage monitoring – optional)
💡 Why this matters:
- Accurate readings even in multi-component gas mixtures
- No need for complex compensation algorithms
- Reliable data for automated control systems (DCS/PLC)
Industrial-Grade In-Situ Design — Built for Harsh Environments
Engineered for direct installation across ducts, stacks, or pipelines, this analyzer eliminates the weak points of conventional systems.
Core Advantages:
- In-situ cross-stack installation → no sample loss or delay
- Explosion-proof (Ex d II C T6) → safe for hazardous zones
- No moving parts → minimal maintenance, long service life
- Resistant to dust, vibration, moisture, and temperature fluctuations
Smart Integration:
- Communication: RS485 / RS232
- Analog output: 4–20mA (2 channels)
- Relay outputs for alarms and control
- Nitrogen purge system for optical protection
👉 Ideal for:
- Power plants (boilers, furnaces)
- Cement kilns & steel plants
- Petrochemical and refining processes
- Waste incineration and flue gas systems

What is an in-situ laser gas analyzer
An in-situ laser gas analyzer is a device that measures gas concentration directly inside a process duct or stack using laser technology (TDLAS), eliminating the need for gas extraction, sampling, or conditioning systems.
What are the advantages of in-situ gas analysis compared to extractive systems?
In-situ analyzers provide:
- Real-time measurement (no delay)
- No sample loss or contamination
- Lower maintenance (no filters, pumps, or coolers)
- Higher reliability in harsh environments
This makes them ideal for continuous industrial process monitoring.
How fast is a TDLAS in-situ gas analyzer response time?
TDLAS in-situ analyzers can achieve T90 response times as low as 4 seconds, making them significantly faster than traditional extractive analyzers, which may take minutes due to sampling delays.
What industries benefit from in-situ laser gas analyzers?
Industries include:
- Power generation (boilers, flue gas monitoring)
- Cement and steel manufacturing
- Petrochemical and refining
- Waste incineration plants
These sectors require real-time, high-reliability gas measurement.
Does an in-situ analyzer require frequent maintenance?
No. Since it has:
- No moving parts
- No sampling system
- No gas conditioning
Maintenance requirements are minimal, mainly limited to optical window cleaning and purge system checks.
Can in-situ laser analyzers measure multiple gases simultaneously?
Yes, depending on configuration, they can measure gases like O₂, CO, CO₂, and CH₄, providing comprehensive process insights in a single system.
