      PTR-TOF proton transfer reaction time of flight mass spectrometer

      Product Description

      The PTR-TOF 4000/4000c proton transfer reaction time-of-flight mass spectrometer combines a proton reactive ion source and a time-of-flight mass spectrometer to achieve online detection of trace amounts of volatile organic compounds and semi-volatile organic compounds (VOCs/SVOCs) in seconds. Qualitative and quantitative analysis of pptv-level VOCs/SVOCs within the company has the advantages of fast response, no need for pre-processing, high sensitivity and low detection limit.

      Application Scope

      Continuous real-time monitoring of ambient air quality (VOCs/SVOCs)；
      Online monitoring of engine VOCs/SVOCs emissions (such as motor vehicle exhaust emissions);
      Real-time monitoring of VOCs/SVOCs in industrial production processes (such as chemical plants, semiconductor industry, etc.)；
      Fixed-point or navigation monitoring of VOCs/SVOCs in chemical plant areas；
      Laboratory analysis (such as observation of VOCs/SVOCs and secondary product photochemical processes in smoke chambers, etc.)；
      Odor source monitoring (such as detection and identification of odorous compounds including organic sulfides, amines, etc.)；
      Identification and detection of characteristic odor components in food, spices, tobacco and other industries；
      Detection and identification of conventional explosives (such as TNT, NG, etc.)；
      Food/drug safety (bacteria/odor/solvent residue) monitoring；
      Medical diagnostic (breath analysis) testing；

      Features

      Real-time online monitoring without sample collection and preprocessing；

      High sensitivity, detection limit as low as pptv level, can detect trace contaminants；

      Fast response speed, can quickly identify pollutants within (50~100)ms；

      High mass resolution for accurate identification of chemical components；

      No carrier gas required, less consumables, and low maintenance costs；

      Adopting a unique design to reduce ion loss and requiring a small amount of sample, it is suitable for micro-environment monitoring.
