Integrated Technology. Precise Results. Mobile Environmental Labs.
Montrose offers advanced PTR instruments optimized for EPA-compliant testing. Our gas chromatography (GC) integration enables isomer speciation, ensuring precise results even for complex compounds, an industry-first that sets us apart. The PTR Vans come equipped with:
- Gas Chromatography (GC) Interface for the detailed chemical analysis of complex mixtures.
- Fourier Transform Infrared Spectroscopy (FTIR) to detect multiple gas species for emission monitoring.
- Calibration and Dilution Systems ensuring accurate and consistent data.
- Real-Time Triangulation and Multivariate Analysis (MVA) for pinpointing pollution sources and allocating odors.
- Weather and GPS Integration provides meteorological data, such as wind speed and direction. Combined with GPS data, it helps pinpoint emissions sources with precision.
- Light absorption gas analyzers monitor inorganic air pollutants such as SO2, H2S, NOx, NO2, and ammonia in real-time for precise air quality assessment.
- Integrated software and mobile applications offer comprehensive data visualization and management.


How it Works:
- Air Sample Collection: mobile air quality monitoring outside the mobile lab.
- Reagent Gas Mixing: for compound reactivity.
- Ionization & Analysis: to separate and quantify molecules by mass.
- Mapping: pollutant concentrations with GPS and MET data for source identification.
- Multivariate Analysis (MVA): to uncover correlations and causations for odor allocations.
