We had touched on the use of running your self-analyzing geiger counter in proportional mode. Even with a single channel analyzer, you just may be able to spot the peak(s) characteristic of Tritium versus, say, radio- tantalum or iron or their daughter radionuclides, etc. Besides, you can measure the activity after flushing out any Tritium and compare with the count from before (allowing for elemental isotope decay, of course) to pinpoint the Tritium contribution. Wouldn't that work?
