F&J - Model MRB500H3 -Tritium Bubbler Collection System

Sample gas enters the instrument and flows through two (2) standard scintillation counter ready vials filled with ethylene glycol, which retain the HTO component. The sample gas, now less the tritiated water vapor, flows through a heated palladium sponge catalyst bed, which oxidizes the sample gas. The oxidized sample gas flows through two (2) more vials with ethylene glycol that retain the remaining tritium components (originally HT and tritiated organics). A precision mass flow controller regulates the sample flow through the instrument. The user has control over the flow rate and catalyst bed temperature. The third vial in each trap serves the function of a trap.
