In fields such as chemical production, pharmaceutical synthesis, and pesticide manufacturing, phosgene is widely used as an important organic intermediate. However, it is also a highly toxic gas that can cause pulmonary oedema, pneumonia, and even death when inhaled. Therefore, real-time, accurate monitoring of phosgene leaks has become critical to ensuring production safety and protecting human health. Traditional monitoring devices either lack sufficient sensitivity to detect trace leaks or require frequent maintenance and short calibration cycles, increasing operational costs and safety risks. The introduction of the Photoacoustic Spectroscopy Trace Phosgene Analyser has completely addressed these challenges, providing a reliable solution for phosgene monitoring.

Who needs the protection of a photoacoustic spectroscopy trace phosgene analyser?

The photoacoustic spectroscopy trace phosgene analyser focuses precisely on monitoring requirements related to phosgene and is a ‘safety tool’ for the following groups of people:

Safety managers at chemical and pharmaceutical companies: During the production, storage, and use of phosgene, it is necessary to monitor gas concentrations in real time to prevent leaks that could cause safety accidents. The high sensitivity and rapid response of the Photoacoustic Spectroscopy Trace Phosgene Analyser allow them to identify potential hazards immediately and take timely measures.

Operators in pesticide production workshops: Pesticide production often involves the use of phosgene, exposing operators to potential risks over long periods of time. This analyser can monitor phosgene concentrations in the working environment in real time, ensuring the safety of operators.

Emergency response teams: In the event of sudden accidents such as phosgene leaks, the portable Photoacoustic Spectroscopy Trace Phosgene Analyser can be quickly deployed to accurately detect leak concentrations and ranges, providing critical data for the formulation of rescue plans and reducing rescue risks.

Work Safety Regulatory Authorities: When conducting safety inspections and supervision of enterprises, reliable monitoring equipment is required to verify the effectiveness of the enterprise's phosgene control measures. The high precision and stability of the Photoacoustic Spectroscopy Trace Phosgene Analyser provide authoritative data support for regulatory authorities.

Core advantages of the photoacoustic spectroscopy trace phosgene analyser: sensitive, reliable, and hassle-free.

As an innovative product based on ultra-sensitive cantilever beam enhanced photoacoustic spectroscopy detection technology, the Photoacoustic Spectroscopy Trace Phosgene Analyser 's advantages stem from its cutting-edge technology and user-friendly design:

1.Trace leaks ‘nowhere to hide’

0.5 ppb detection limit: Utilising an ultra-sensitive patented optical cantilever microphone combined with a quantum cascade laser (QCL) light source, it can detect phosgene concentrations as low as 0.5 ppb, enabling precise identification of even minor leaks.

Rapid response with no delay: Response time can be customized according to requirements (from 10 seconds to several minutes), enabling near-real-time reflection of phosgene concentration changes and providing valuable time for emergency response. 

2. Long-term stability and ‘maintenance-free’

Direct absorption measurement, no drift: Direct absorption detection is used, and zero background characteristics ensure long-term high stability, avoiding measurement errors caused by drift in traditional equipment.

Calibration cycle lasts for years: Recalibration intervals can last for months or even years, greatly reducing maintenance costs and downtime, keeping the equipment in optimal working condition.

3. Flexible adaptation to multiple scenarios

From fixed to mobile, comprehensive coverage: We offer fixed devices with 19" 3U rack-mounted installation, as well as portable enclosures for different scenarios, such as fixed monitoring in workshops and detection of predictable leakage areas. Multiple devices can also be integrated into a mobile monitoring system for quick deployment to different critical measurement points.

User-friendly operation and remote control: Equipped with a 7-inch widescreen display, the intuitive user interface supports both numerical and graphical display of results, making operation simple and easy to understand. Additionally, remote operation via a local area network is supported, allowing users to view data anytime using a smartphone, tablet, or computer for convenient management.

Outstanding features of the photoacoustic spectroscopy trace phosgene analyser: the details reveal the truth.

No consumables, no chemical reagents: No need to frequently replace consumables and chemical reagents, reducing usage costs and operational complexity.

Low sample volume, high-efficiency detection: Only a few millilitres of sample volume are required to complete the detection, reducing the environmental impact of gas sampling while improving detection efficiency.

Wide dynamic range: The dynamic range exceeds five orders of magnitude (100,000 times the detection limit), enabling detection of trace leaks as well as monitoring of higher concentrations of phosgene.

Strong environmental adaptability: It can operate stably within a temperature range of 0°C to +49°C, a pressure range of 750 mbar to 1050 mbar, and a humidity environment without condensation, unaffected by temperature and pressure changes, ensuring measurement accuracy in complex operating conditions.

Choose the Photoacoustic Spectroscopy Trace Phosgene Analyser to make safety ‘visible’

Whether for continuous monitoring during routine production or emergency detection during sudden accidents, the Photoacoustic Spectroscopy Trace Phosgene Analyser leverages its high sensitivity, stability, and flexibility to establish a robust safety barrier for phosgene-related scenarios.
