**Smaller and Lighter "Breath Gas Analyzer": Miniaturized Prototype Development Completed**

Achieved 200 ppb-level Ultra-Trace Toluene Detection Performance and Low-Cost Manufacturing

iSensIRs has completed the development of a compact prototype that significantly reduces the manufacturing cost of a gas analysis system utilizing its mid-infrared quantum cascade laser (QCL) spectroscopy technology.

Through this development, we expect to enhance operational efficiency and market accessibility while maintaining performance close to that of existing large-scale analytical equipment.

1. Key Specifications and Technical Indicators

 - Detection Performance: Capable of detecting ultra-trace toluene at 200 ppb or below

 - Product Specifications: Compact form factor of 30 x 20 x 20 cm

 - Enhanced Accessibility: Significantly lowered equipment adoption costs, expanding the potential for operation in diverse environments

With this prototype development as a starting point, iSensIRs will accelerate efforts to achieve its vision of "precision diagnostics anytime, anywhere."
