1000 cc Tritium ion chamber: in line detector process system

---

The 1000cc TRITIUM ION CHAMBER  specialized ceramic feed through allows a bias of up to 100V and an anode signal as low as 1 fA (corresponds to 1 µCi/m3 of tritium). When combined with Tyne Engineering's preamplifier and controller package or signal processor this makes an ideal tool for tritium measurement in any process.

• 1000cc ion chamber suitable for μCi/m³ to Ci/m³ of Tritium
• Bakeable to cleanse contaminated surfaces from ionization chamber
• Full vacuum to 150 psig
• Precise, tested and proven 1000cc geometry.
• Can bias anode up to 100V from ground
• Inlet precipitator
• Can be used in explosive environment with purge equipment
• Use in a process line or for room air measurements
• Flows up to 1 l/s

The inlet and outlet VCR 8 connectors allow the chamber to be easily mounted into an existing process line. The internal anode is connected to a floating BNC which can be biased up to 100 V. The high resistance ceramic of the feed through allows the ionization chamber to measure ionization currents as low as 1 fA (1 µCi/m³ of Tritium). The bias voltage is also connected to an inlet precipitator to remove any ionized particles carried into the chamber. The maximum inlet flow rate of 1 L/s ensures that all particles are neutralized before entering the chamber. The ionization chamber is an approved pressure vessel that can handle up to 150 psig, is bakeable up to 350°C and is 1x10E-9 Helium leak tight. The electro-polished interior ensures low tritium hang up, but in the case of contamination the chamber is easily cleaned with a moist air purge.

The ionization chamber is typically connected to Tyne Engineering's preamplifier or signal processor. The preamplifier is a multi-ranged amplifier that connects to a remote controller providing the operator maximum flexibility in measuring the amount of tritium, auto zeroing and alarm functions. The signal processor is a low cost device that provides the bias and converts the 1 fA signal to an easily handled 0 – 10 V signal that can be integrated into any existing data acquisition system.
