Methane from different sources was simultaneously measured for tritium and 14C.

Ultra-low-background detectors allow for significantly reduced sample size.

Dual-isotope measurements are well-suited for samples with elevated tritium levels.

Low-level tritium samples are better suited for commercial separation and counting.
