Ultra-low measurements, delivered in real-time.

The Montrose Proton Transfer Reaction Time of Flight Mass Spectrometry (PTR-TOF-MS) Mobile Laboratory is a revolutionary technology that provides ultra-low detection of organic and inorganic compounds in real-time with capabilities to map a facility or community.

Enabled with ultra-low detection Parts Per Trillion limits, the mobile platform can track virtually any Volatile Organic or Inorganic Compound at a rate of up to one data point per half-second.

This device provides ultra-low detection of organic and inorganic compounds in real-time with capabilities to map a facility or community. It incorporates additional components to quickly determine where emissions are originating for use:

  • Fencline Monitoring
  • Odor Complaints and Allocation
  • Fugitive Emission Identification and Measurement
  • Emergency Response
  • Industrial Hygiene
  • Source Allocation
  • Ultra-low Detection for Title V Major Source Declassification

The Montrose PTR-TOF-MS Mobile Laboratory is enabled with triangulation platforms that pull in data through…

Taking a sample gas (the air outside of the vehicle).

Mixing it with a reagent gas selected for reactivity to the selected compound.

In an ionization chamber that gives energy to the molecule.

The different masses of all the molecules are separated and counted.

This allows us to quantitate how many are in the sample.

Using GPS and MET data, we can map out the concentrations to pinpoint where the source of the molecule concentrations are coming from.

This enables us to perform mobile on-site testing for an unlimited variety of compounds.

During odor acclocation projects, our team uses a multivariate analysis (MVA) computer program to determine correlations and causations.
