Raman Gas Analyzer – Real-Time Multi-Gas Analysis Without Limits
A New Era of Gas Analysis – No Carrier Gas, No Complexity
Traditional gas analysis methods like GC or MS often require complex sample preparation, carrier gases, and high maintenance.
The Instrava Curated Raman Gas Analyzer breaks these limitations by leveraging laser Raman spectroscopy, enabling direct, real-time, in-situ gas analysis—even for gases that are difficult to detect using conventional technologies.
With fiber-optic remote sensing, multi-gas simultaneous detection, and second-level response time, this analyzer is ideal for modern industrial environments where speed, flexibility, and reliability are critical.

What is a Raman gas analyzer and how is it different from traditional gas analyzers?
A Raman gas analyzer uses laser Raman spectroscopy to directly measure gas composition without sampling systems or consumables. Unlike GC (Gas Chromatography) or NDIR analyzers, it can detect all gas types—including symmetric molecules like H₂ and N₂—in real time with minimal maintenance.
Can Raman gas analyzers measure hydrogen (H₂) and nitrogen (N₂)?
Yes, this is one of the biggest advantages. Raman technology can accurately detect H₂, N₂, and O₂, which are difficult or impossible for many traditional analyzers like NDIR. This makes it ideal for hydrogen energy, ammonia synthesis, and semiconductor industries.
Is a Raman gas analyzer suitable for harsh industrial environments?
Absolutely. With a fiber optic probe (up to 100 meters), the analyzer can be installed in a safe area while the probe operates in:
- High temperature zones (up to 200°C)
- High pressure environments (up to 4000 kPa)
This makes it perfect for petrochemical, energy, and hazardous process applications.
Does a Raman gas analyzer require calibration or consumables?
No carrier gas, no columns, and no chemical consumables are required. Maintenance is minimal and includes:
- Periodic optical cleaning
- Filter and desiccant replacement
This significantly reduces operational cost compared to GC or MS systems.
What industries benefit most from Raman gas analyzers?
Raman gas analyzers are widely used in:
- Hydrogen energy & fuel cells
- Petrochemical and refining
- Semiconductor manufacturing
- Gas purity analysis
- Research laboratories
Any application requiring fast, multi-gas, high-precision analysis will benefit.
How accurate and fast is a Raman gas analyzer for real-time monitoring?
This analyzer offers:
- Accuracy ≤ ±1% F.S.
- Response time ≤ 30 seconds
It enables continuous, real-time monitoring, making it suitable for both process control and safety-critical applications.
