Volatil-Analysator für organische Verbindungen BTEX


Die Messtechnik des VOC72M, die der Norm EN 14662-3 (2005) und EN 15267-1 (2009) für die Messung von Benzol entspricht, basiert auf Gaschromatographie (GC) in Verbindung mit einem Photoionisationsdetektor (PID)

Kompakter und vollautomatischer Analysator, der die gleiche Leistung wie Laborchromatographen bietet; besonders gut geeignet für stationäre oder mobile Stationen zur Überwachung der Luftqualität.
– Standardmäßig gemessene Verbindungen: Benzol, Toluol, Ethylbenzol, m+p-Xylol, o-Xylol, 1-3 Butadien (andere Verbindungen auf Anfrage)

Schnelle Überprüfung der Chromatogramme direkt am Bildschirm möglich, ohne den Einsatz eines Computers

  • Standard measured compounds: Benzene, Toluene, Ethylbenzene, m+p-Xylene, o-Xylene, 1-3 Butadiene…
  • Performs all the functions, such as: sampling, analysis and data management, in a simple and completely autonomous mode
  • Self-contained, completely automated and ready to use in less than 30 minutes
  • GC column equipped with an innovative liquid-cooler; retention times are stable even with a fluctuating temperature
  • Long-life capillary column
  • High sensitivity, stable and linear response PID detector
  • Ultrafast trap heater (heating rate >160°C/second)
  • Quick check of the chromatogram peaks possible directly on-screen, without the use of a computer
  • Low memory effect allowing the automatic calibration of the analyser on a single cycle without an external PC
  • Carrier Gas : N2 (Nitrogen)
  • Ambient air monitoring
  • Monitoring of industrial sources emitting VOCs
  • Photochemical pollution studies (stationary and mobile laboratories)
  • Other compounds on request: hexane, trimethylbenzene, i-octane, styrene…
