– Operating Principle –
The MARC 7000 bubbler is used for monitoring atmospheric tritium concentration levels in vapor and gas form from chimneys, ventilation systems, hoods, premises, or the environment.
The MARC 7000 samples water vapor form of tritium (HTO) by bubbling in water in the first two pots, after particle filtration in the air. Gas form tritium (HT) or organic (OBT) is oxidized in an oven equipped with a catalyst, and then trapped by the same principle in the last two pots. The measured tritium activity is then reported to the volume of air passed through the device to determine the volumetric activity of tritium in the air (in Bq/m3 of air).
– Performance –
(CEA Marcoule test report June 2006)
– Air Flow Process –
A pre-filter paper at the entrance (∅ 45 mm) prevents the aspiration of dust, 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.

– FAQ –
Yes, you can customize the Marc 7000 according to your needs. You can add the following options to the bubbler: TOR Arte – Alarm Relay: Type T.O.R, JBUS Protocol, and Ethernet communication.
The device is equipped with a cooling circuit that maintains the trapping solution at an average temperature of 7°C (for an ambient temperature of 20°) and thus prevents the loss of the sample solution by evaporation. This option is essential for weekly or longer duration sampling.
