  • Analysis of VOCs emissions from a car painting line
  • Clean air room monitoring
Category:

Principle :

The DET QMS is an online process mass spectrometer using a quadrupole with pre-filter, electronic impact for ionisation and an SEM discrete dynode for detection.

Chromatotec® proposes the DET QMS : a universal mass spectrometer system for fast, precise and sensitive online gas analysis with uptimes close to hundred percent.

The DET QMS is a powerful tool for reliable process monitoring and process control. Routine analysis is performed with a controlled sample flow and extremely good and long-term stability. This instrument is well suited for various different industrial processes.

Advantages of the system :

  • Design to couple with 1 or multiple gas chromatography systems
  • Miniaturization, sensitivity, mobility and flexibility are its main features. Everything, from primary vacuum pump until detector and electronics are in a 19“ in rack 10U.
  • Flexible analysis system for a broad range of applications
  • Full automatic operation
  • Outstanding analytical performance
  • Measurement of main components and trace components in gas mixtures in one step
  • Measurements of chemical reactive and corrosive gas components possible
  • Customized hardware and software configurations
  • Excellent long term stability and reproducibility of the analytical results
  • High availability
  • Low cost of ownership

Options :

  • On-line results are transmitted via a MODBUS / JBUS or MGS1 communication protocol
  • Analog output 4-20 mA or 0-10 V
