The Model 336 Tritium In-Air Collector is a desktop or rack-mounted tritium sample collecting solution. It features a maintenance-free diaphragm air pump to pull air through six cascaded 20 mL vials. The first three vials collect HTO (tritiated water vapor) from the air being monitored, the first vial catching the bulk of the HTO, while the second and third vials ensure that virtually all of the HTO is collected. The air is then oxidized by an internal catalyst, converting all the HT (tritium gas) still in the air to HTO to get collected by the last three vials.

Backflow prevention ensures the catalyst is protected from sampling fluid. Airflow is measured with a mass-flow sensor, with the value displayed on the front LCD. Catalyst temperature setpoint and real-time reading are conveniently displayed on the front panel. The instrument has only a few simple controls, making it easy to use, and comes in a case which can be installed in a standard 19-inch rack or set on a desktop.
