A revolutionary integration
Green River Technology integrates portable TOF MS - MS 200 and unmanned ground vehicle together - GR - 7200, making detective analyzer to go further, conquering more demanding missions, with data and image transmitting back to the control centre, backing-up to sky-drive simultaneously.
GR - 7200 can help you to collect the data safely, get any circumstances under your control.
Portable Time - of – Flight Mass MS200
MS-200 is a portable, battery powered mass spectrometer for gas analysis entirely contained in a single case.
MS - 200's membrane inlet concentrator allows a wide range of gases to be identified and measured from the low p.p.b. range up to percent levels.

Residual flammable gases analysis at the explosion incident site, Aug. , 2014, Kaohsiung
The lowest detectable molecular is 1 amu, MS200 can detect low concentration of flammable gases effectively. E.g. methane or propene
Application on flammable gases analysis
Spectrum of 1 p.p.m. flammable standard gas.
Flammable gases qualitative and quantitative rapidly, display on the window with the compound name and its own concentration.
Application - On emergency mission - Source of pollution tracking
Pollution source tracking mode is available.
Can be complied under high concentration background.
Operating on moving vehicle, once close to the pollution source, the counts of spectrum will increase obviously.
MS200 can identify the compounds and measure to p.p.b. level.
Application Odor compounds monitoring in ambient - operate on moving vehicle
The VOCs concentration monitors around one of Science Park in Taiwan.

Other applications include
The detection and analysis of volatile and semi-volatile organic contaminants(VOCs) on remediation sites - as a fast and cost effective screening process prior to site renewal,
Urban air quality research - measuring the spatial distribution of pollutants,
Industrial hygiene - including the quality analysis of air cleaning systems,
Emergency response testing - fast unambiguous identification of unknowns,
Fire and crime scene investigations - identifying accelerants used in arson at the fire scene.
