A safe, efficient and inexpensive method for preparing small quantities of tritiated water, sulfuric acid and trifluoroacetic acid is described. The preparation involves introducing the preassayed tritium sample into a carrier gas, 0.5% hydrogen in air, passing over a palladium catalyst heated to 800° C. The resulting tritiated water is gradually eluted from the catalyst and collected in suitable traps.
