Abstract
The operation and performance of the Finnigan MAT automated Breath Gas Analysis System for the routine analysis of 13C breath tests taken in 20‐ml Vacutainers is described. Up to four samples per hour can be analysed with a standard deviation of δ13C of o being achieved over the range 10–50 μmol CO2. The equipment can also be used for the automatic measurement of the concentration and 13C enrichment of CO2 derived from carbonate or bicarbonate solutions, including blood and other physiological fluids.This publication has 3 references indexed in Scilit:
