Description

The “Tri-Car” (Tritium – Carbon) family of 3H and 14C airborne samplers can be configured to sample either quantities of 3H in the form of water or 14C in the form of carbon dioxide. A configuration is available as a differential sampler which converts other forms of 3H and 14C into water and carbon dioxide to obtain a separate sample of HT, elemental hydrogen, 14CO, carbon compounds, and elemental carbon. This configuration of sampler uses a catalytic converter to oxidize these other forms of 3H and 14C into water and carbon dioxide. The sampler design uses a parallel flow path for the HT, elemental hydrogen, 14CO, carbon compounds, and elemental carbon reducing the statistical uncertainty of the differential measurement. Sample flow measurement and control as well as temperature, pressure, and relative humidity measurements are provided for all flow paths. The sample flow rate measurement as well as the total sample volume is calculated at standard temperature and pressure (STP). Alarms are provided for the measurement values and all data is stored locally and can be transmitted to a remote PC. The standard sorbents used are silica gel for 3H and NaOH for 14C. Optional sorbents can be provided depending on the sampling needs.
