The natural ¹⁴C label can be artificially enriched (even by orders of magnitude) to mark drugs and track their metabolic pathways in human clinical trials.

The unprecedented C14-SCAR dynamic range can enable seamless measurements over more than 5 decades of radiocarbon concentration (0.1 – 100000 pMC).

Since only small  samples (urine, plasma, feces, etc.) are typically available, a specific, smaller volume model of the instrument,  named BIO-SCAR, has been developed for this kind of application.
