CONTINUOUS MEASUREMENT SYSTEM OF 14CO2 IN EXHALATION

摘要

PROBLEM TO BE SOLVED: To provide a method and a system capable of determining pharmacokinetic characteristics useful for micro dose clinical tests, etc., by measuring ¹⁴CO₂ at exhalation.;SOLUTION: The method, for continuously measuring ¹⁴CO₂ in exhalation from a test subject, includes a step (1) of absorbing total CO₂ in exhalation from the test subject into a basic compound aqueous solution, and a step (2) of measuring a ¹⁴CO₂ amount absorbed into the aqueous solution.;COPYRIGHT: (C)2011,JPO&INPIT
