⚠️ V***r detection is not aerosol detection.

The same chemical can create a different detection challenge depending on its physical form.

A v***r is present in the gas phase. An aerosol consists of solid particles or liquid droplets suspended in the air. These forms do not travel through a detector in the same way, and some systems may need to filter, collect, heat or prepare an aerosol sample before analysis.

This leads to an essential operational question:

Can my detector detect this threat across the different physical forms in which it may be encountered?

Proengin’s filterless flame spectrometry architecture draws ambient air directly into the flame, enabling native and continuous detection of gas, v***r and aerosol. Dedicated sampling accessories extend this coverage to liquid and solid sources when required.

Because detecting the substance is only part of the challenge. Detecting it in its actual physical form matters too.

Our teams remain operational and accessible throughout the summer.

Take some time for yourself, enjoy the summer, and stay connected! 🏖️

🔧 Is your detector ready for its next mission?

A detector can appear fully operational while wear, contamination, or measurement drift develops unnoticed.

Preventive maintenance helps identify issues early, maintain reliable detection performance, and reduce unexpected downtime.

Proengin experts inspect, clean, adjust, test, and calibrate your equipment, then provide a detailed service report.

📅 Check your detector’s last service date and plan its next maintenance visit.

📢 New blog: Rethinking CBRN Protection

Critical infrastructure and major events face increasingly diverse and unpredictable threats.

Our latest blog explores how connected fixed and mobile detectors, drones, and real-time data sharing can extend operational awareness and support faster, more coordinated decisions.

🚨 Carbonyl Sulfide: An Invisible Industrial Threat

Carbonyl sulfide (COS) is a toxic and flammable gas that may be present in refineries, natural gas facilities and other industrial environments.

It is colourless, heavier than air and cannot be reliably detected by smell—making rapid detection essential.

The AP4C detects COS within seconds from concentrations as low as 0.18 mg/m³, using its sulfur channel, and is flameproof for use in potentially explosive atmospheres.

When human senses cannot warn your teams, how quickly can your detectors respond?

🧬 CDC Categories A, B and C: What do they really mean?

When biological threats are described as Category A, B or C by the CDC, it is easy to assume that the letters simply rank agents from the most dangerous to the least dangerous.

That is not what the CDC framework was designed to do.

The categories were developed to help public health authorities prioritize preparedness against potential bioterrorism agents. They consider several factors, including potential health impact, ease of dissemination, capacity to cause public fear and disruption, and the level of surveillance, diagnosis and response planning required.

🔴 Category A: Highest preparedness priority
These agents may cause major public health consequences, high mortality or widespread disruption, and require specific preparedness measures. Examples include anthrax, smallpox, plague and botulinum toxin.

🟠 Category B: Second preparedness priority
These agents are generally moderately easy to disseminate and usually cause lower mortality than Category A agents. They still require reinforced surveillance and diagnostic capacity.

🔵 Category C: Emerging threats
This category covers pathogens that could become significant future threats because of their availability, ease of production or dissemination, and potential public health impact.

⚠️ But focusing only on Category A is not enough
A biological attack may not be intended solely to cause fatalities. An adversary may instead seek to incapacitate populations or fighter, overwhelm healthcare services, disrupt essential operations or generate widespread fear. Agents outside Category A may therefore remain operationally significant, depending on the objective, dissemination method and exposure conditions.

👉 Threat Detection Cannot Be Limited to a Category.
Proengin’s flame spectrometry-based biological detection does not classify an airborne threat as Category A, B or C. It continuously monitors the surrounding air for sustained biological aerosol anomalies, without requiring operators to preselect a specific agent or CDC category.

This broad approach supports the detection of biological threats across different preparedness categories, whether they may cause death, illness or operational incapacitation. The alert provides the first layer of the response chain, helping operators trigger targeted sampling, identification and protective action while the airborne signal is still present.
