Integrated Calibration Device
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
Attention: The multiport valve is mandatory for using the internal calibration system!
