Radio-Synthesis With The LabLogic Tri-Sorber Tritiation Manifold
There is an increasing need for radio-synthesis applications involving high specific activity tritium labeling and with it, a greater demand for better tritium handling solutions. Large amounts of tritium can be easily sequestered in uranium and through controlled application of heat, this tritium can be released as required. LabLogic’s Tri-Sorber is a new instrument which is the very first of its kind: a self contained instrument for the controlled heating and release of tritium sequestered in uranium metal.
The Tri-Sorber provides easy, quantitative reversible thermal decomposition and formation of uranium tritide – which is formed rapidly by depleted uranium ( 238U) in the presence of T2 at temperatures between 250 and 300 degrees Celsius. Heating the materials further results in the decomposition of the tritide back into its constituent uranium metal and tritium gas.
The LabLogic Tri-Sorber Tritiation Manifold is designed with the durability and safety that radio-synthesis applications demand. The unit is made from stainless steel with orbital butt welding connecting fixed elements. Where sections of the unit are designed to be taken apart, the sections are secured with face-seal high vacuum bellows valves.
Safety has been built into the Tri-Sorber’s design from the ground up, with continuous monitoring of temperature and pressure and automatic shutoffs in place to prevent the system from operating outside of safe parameters. The vacuum pump used in the Tri-Sorber includes another automatic shut off valve to isolate the system when it is not in use.
The instrument is easy to use, providing a straightforward process for radio-synthesis tritiation. T2 is admitted to one of the Tri-Sorber’s three integrated uranium beds following a heat activation under vacuum conditions. UT3 is formed rapidly and the reaction flask us then placed and evacuated, with He3 being pumped off. The desired amount of T2 delivered to the reaction flask is released through the controlled heating process and the flask closed off, with the excess being reabsorbed by the uranium beds.
Unreacted T2 is collected by the Tri-Sorber’s secondary uranium bed (which is reserved for waste products from testing applications) and deuterium for later use in radio-synthesis pilot studies may be stored in the Tri-Sorber’s third uranium bed.
