H3R 7000 : Tritium Condenser – Advanced Trapping of Atmospheric Tritium in Vapor Form

– Trapping Performance –

The H3R 7000 displays an HTO trapping efficiency of 100%, no dilution factor, a detection limit of 0.01 Bq/m3, a cross-contamination rate of ± 0.1%, and an average sampling duration of 40 minutes.

– Operating Principle –

The H3R 7000 samples tritium in the form of water vapor through a process of cryogenizing the water vapor present in the ambient air.

Simultaneously, the H3R 7000 measures and automatically calculates the absolute humidity of this air to accurately determine the amount of water present per m3 of air, expressed as absolute humidity in g/m3 or ml/m3 of air.

On average, less than forty minutes are needed to collect a sufficient amount of water for the delayed measurement of the tritium activity of this water by liquid scintillation counting.

Once the tritium activity is measured and expressed in Becquerels, for example, the operation to obtain a tritium activity reported per m3 of air is as follows:

Volumetric activity of tritium in the air (Bq/m3) = = \( \frac{\text{ Tritium activity of the measured volume (Bq)
)}}{\text{ Measured Volume (ml)}} \Absolute humidity of the air (ml/m3)\)
