Applications of Stationary Photo Ionisation Detectors

PID (Photo - Ionisation - Detectors) are used to detect substances which are not detectable with other methods, like in solvents or fuels. These so – called VOCs (Volatile Organic Compounds) are not only present in all chemical industries, but also in areas where one would not expect them. The food industry is using fast ink jet printers to print the best before date on food packages, for example; these printers use relatively little ink. One gallon of ink is enough to print 2 – 3 million characters, but these printers work extremely fast: they can mark 10,000 packages per hour.
