Time Of Flight Mass Spectrometer

The Time of Flight Mass Spectrometer are providing rapid and sensitive gas analysis for environmental monitoring and research applications


The SDI-TOF-MS perform measurements over a wide range from ppt to percent concentrations of most ambient gases of environmental interest.

Ease of operation and ability to produce stable long-term measurements of the constituents of ambient air makes the equipment well suited to air-pollution monitoring as well as environmental research.
The SDI-TOF-MS instrument is fitted with two selectable ambient air sample inlets:
Capillary inlet for rapid (<1 second) high sensitivity analysis of inorganic gases such as CO, CO2, NO, NOx , N2O, Xe, Kr, SO2, O2 and others at less than 1ppm to percent concentrations.
Membrane inlet for very high sensitivity analysis of volatile organic compounds at the ppt and ppb level within one minute. Compounds of interest include benzene, toluene, xylene (BTX), trichloroethylene, tetrachloroethylene, methane, ethene, formaldehyde, styrene and most other toxic organic compounds of environmental interest.
