Temperature-dependent integrated exit flux of m/z = 44 (CO2) and m/z = 45 (13CO2) normalised via Ar from the TAP experiment where an oxygen rich CO/O2 mixture (1:2 molar ratio, 6.6% CO 13.4% O2) was pulsed over a 13CO*-covered Pt/SiO2 catalyst while heating from 25–350 °C at a heating rate of 8 °C/min.
