PTR TOF MS (Proton-Transfer-Reaction Time-of-flight Mass Spectrometer) is a versatile tool for fast and sensitive measurements of trace Volatile Organic Compounds (VOCs) at a high time resolution.


• Real time quantitative analysis of the entire mass range of Volatile organic compounds (VOCs)

• Detection of all compounds with higher proton affinity than water using H3O+, as Primary ion. Hence N2, O2 , Ar, CO2 etc in air are not detected.

• Option to use Kr+, which has higher Ionization potential than H3O+, as Primary ion

• Detection and quantification of substances (including inorganic) such as NO2, SO2, CO2, CO are also possible using Kr+ as Primary ion.


• Mass range: 1-10,000 amu

• Detects upto 1000ppbv

• Mass resolution: > 2000 m/Δm (FWHM) for m/z > 79


Real time analysis of gases in situations such as ambient air monitoring, food flavour and fragrances, breath analysis, geological analysis, forensic investigation, waste incineration etc.
