Abstract Information :
Increasingly the amount of biogenic versus fossil fuel is becoming important from a fiscal viewpoint. An overview of an eminently elegant and relatively simple method to determine the proportion of material arising from biogenic sources will be reviewed by determining the ratio of 14C to 12C in CO2. This is determined by obtaining a sample over a number of days and the resulting ratio of average 14CO2 to 12CO2 determined using AMS (Accelerator Mass Spectrometry). The talk will briefly cover:
- representative sampling of CO2;
- measurement of the sampled 14C;
- calculation of the biogenic CO2 fraction in the stack gas emitted during the sampling period.
