Most gas detection systems are built for normal conditions: stable environments, predictable risks, and the luxury of time for lab analysis. But what happens when none of that applies? In a CBRNE scenario, air quality can shift in seconds. Missing a single compound, or identifying the wrong one, can have catastrophic consequences for responders and the public alike.

CBRNE: Not just a military concern anymore

Traditionally, CBRNE preparedness has been associated with armed forces and national defense. But today the landscape has changed. Civilian sectors are increasingly at risk from both accidental and intentional releases of hazardous chemicals.

Industrial accidents, transportation incidents, and attacks on critical infrastructure can all create CBRNE-like conditions.

Public safety agencies, environmental protection agencies, law enforcement and emergency medical services now face the same demands once reserved for specialized defense units. As a result, the need for versatile, field-ready CBRNE gas detection solutions, is spreading beyond military circles into civil protection, law enforcement, and infrastructure safety.

In many situations, rescue personnel rely on fully equipped mobile laboratories that house a wide range of measurement devices and laboratory instruments. While highly capable, these mobile labs can be cumbersome in confined environments and are extremely expensive, often costing over €1–2 million. For this reason, rescue services also need flexible, portable measurement devices that can be integrated into mobile laboratories yet detached for field use, providing greater agility in demanding and dynamic situations. This type of technology is increasingly becoming a key part of modern first response gas detection strategies.

The hidden dangers of airborne threats

Much of the challenge comes from the nature of airborne threats themselves.

• Chemical Warfare Agents (CWAs) like Sarin, VX, and Mustard Gas can be lethal at extremely low concentrations.
• Toxic Industrial Chemicals (TICs) such as ammonia and hydrogen cyanide are widely produced and transported, and accidental releases can be devastating.

Many of these gases are odorless, invisible, or act so quickly that symptoms appear only after exposure has already caused harm; by the time a detector alarms, it may be too late for the operator, which is why the possibility of remote operation is often critical. This unpredictability means responders cannot rely on experience alone. Only precise, real-time data can provide a reliable picture of the environment.

The problem with traditional detection methods

Conventional gas detection and sampling methods often fall short in high-risk CBRNE environments:

• Slow turnaround: Collecting, moving, and analyzing samples in a lab takes too long, which is a problem when lives are at risk.
• Narrow scope: Most handheld sensors can only detect a few specific compounds, leaving responders unaware of unknown threats.
• Not designed for multi-threat scenarios: In real-world situations, several gases and byproducts often appear at the same time.
• Not designed for long term monitoring: Traditional methods struggle with prolonged high concentrations, such as during decontamination, or with gases that are continuously present and must stay within safe limits.

When these demands in the field exceed what traditional tools can provide, it becomes clear that a different approach is needed.

What real-Time FTIR gas monitoring brings to the table

Fourier Transform Infrared (FTIR) spectroscopy is one technology filling this gap. By analyzing the unique “spectral fingerprint” of gases in real time, FTIR enables responders to:

• Detect dozens of gases simultaneously
• Identify unknown compounds by comparison with extensive libraries
• Monitor up to 50 compounds you have chosen, live
• Quantify concentrations with laboratory-grade accuracy on the spot

In practice, this means faster decisions, safer teams, and fewer assumptions in the field. For example, FTIR has been studied for use in confined environments such as industry environments, submarines and other vehicles, where ammonia, carbon monoxide, and other byproducts can build up quickly. In these situations, continuous monitoring gives a much clearer picture of air quality than occasional spot checks.

For example, our FTIR analyzers provide real-time identification and quantification from sub ppm to tens of % of:

Ammonia	NH3
Hydrogen chloride	HCl
Hydrogen Cyanide	HCN
Phosgene	COCl2
Hydrogen Fluoride	HF
Chloropicrin	Cl3C−NO2

We won’t list all 5000+ components covered by our spectrum libraries, but if it’s toxic, airborne, and needs detecting, we probably cover it.

Rethinking preparedness in the CBRNE era

As the nature of threats evolves, so too must our approach to preparedness. Planning for the unknown is now essential, and the adoption of advanced monitoring technologies is accelerating in civil security sectors.

Agencies that previously depended on single-compound detectors or slow lab analyses are now pursuing systems that deliver complete, instantaneous data.

This shift represents a technological upgrade as well as a cultural one: moving from reactive response to proactive preparedness. Real-time gas detection has become a necessity in ensuring readiness for the complex challenges posed by CBRNE threats.

Quantify the known, identify the unknown CBRNe threats may never be fully predictable, but the ability to measure and understand the air around us in real time transforms the way we respond. To explore practical solutions for these challenges, visit our CBRNe gas detection application page.
