– Operating Principle –

The MARC 5000 captures tritium in water vapor form (HTO) using the bubbling principle in two bubbling pots, with prior filtration of particles in the air. After sampling, the tritium activity in the water from the bottles is measured later by liquid scintillation counting. The measured tritium activity is converted into volumetric activity in the air (in Bq/m3), based on the volume of air treated by the device.

This model is equipped with a cooling circuit that maintains the trapping solution at an average temperature of 7°C (in a 20°C environment), thus preventing the evaporation of the sample solution. This feature is crucial for samplings over a week or longer.

– Performance –

(CEA Marcoule test report June 2006)

– Air Flow Process –

A pre-filter paper at the entrance (∅ 45 mm) prevents dust aspiration, and the electronic flow meter is protected by Gortex® filters. The air flows in glass vials (250 ml capacity) through stainless steel air tubes. The airflow can be adjusted from 10 to 50 liters per hour, regulated by a certified flow meter.
