Influence of the relative ionisation<br />
efficiency of 12 C 17 O 16 O versus 13 C 16 O 2<br />
Assume 13 δ = –10 ‰, 18 δ = 40 ‰ <strong>and</strong> 17 Δ = 0 ‰.<br />
Relative difference in<br />
45<br />
δ / ‰<br />
ionisation efficiency<br />
0 –7.968<br />
0.001 –7.966<br />
0.01 –7.949<br />
0.1 –7.772<br />
<strong>How</strong> good is the assumption that relative ionisation<br />
efficiencies are the same?
