PRISM-PTR-6K — Real-Time VOC Analysis at 6000 Resolution

The PRISM-PTR-6K delivers 5-ppt detection limits and 100-millisecond response times through Proton Transfer Reaction Time-of-Flight Mass Spectrometry. Unlike conventional GC-MS requiring 15-60 minute analysis cycles, PRISM captures the complete mass spectrum (1-1000 amu) in a single microsecond pulse — enabling true real-time molecular surveillance for atmospheric research, industrial compliance, and emergency response applications.

Applications include urban air quality monitoring, industrial fence-line surveillance, vehicle-mounted plume tracking, semiconductor airborne molecular contamination (AMC) detection, breath analysis research, and food flavor profiling. The system supports switchable reagent ion chemistry (H₃O⁺, O₂⁺, NO⁺, NH₄⁺) to cover hydrocarbons, halogenated compounds, and highly oxygenated organics without hardware modification.

Key Specifications

  • Mass Resolution: 6000 FWHM (separates C₂H₄⁺ 28.0313 from CO⁺ 27.9949)
  • Detection Limit: ≤5 ppt (p-xylene, 50s accumulation)
  • Response Time: ≤100 ms (10 spectra/second acquisition)
  • Mass Accuracy: Better than ±0.005 u
  • Dynamic Range: 5 orders of magnitude (ppt to ppm)
  • Reagent Ions: H₃O⁺, O₂⁺ standard; NO⁺, NH₄⁺, Ar⁺, Kr⁺ optional
  • Operating Temp: 0°C to 45°C (vehicle-mount ready)
