The D-T mixture (Deuterium/Tritium), actually a three-component mixture of D2, DT and T2 at cryogenic temperatures represents the fusion reactor fuel. Analyzing its components is possible using mass spectrometry, but the method and apparatus are expensive. Establishing a simple, low cost method for in-situ measuring the D/T ratio, without sampling, really represents a challenge.
