Internal Calibration System (ICS)

Use a port of your multiport valve for calibration: This built-in calibration system dynamically dilutes VOC gas standards with VOC free air (zero air) to measure calibration factors, linearity, background and LODs. With the internal multiport-valve, measurements can be fully automated.

The internal calibration system was made to make regular calibrations of our PTR-MS instruments easier and more effective. Let us summarize some quick facts about the internal calibration system.

  • Catalyzer and Flow controller (up to 400 sccm) for generation of zero air 
  • passivated Flow controller up to 50 sccm (20 or 100 sccm optional available) for calibration gas (gas tank and pressure reducer NOT included!)
  • Dilution ratio: 1:400  to undiluted
  • Multiport valve allows automated switching to calibration system 
  • Automated calibration measurements
  • Automated background measurement
     

Important Note: The multiport valve is mandatory for using the internal calibration system!
