摘要：

Flame-sampling photoionization mass spectrometry, using continuously tunable synchrotron radiation, offers important advantages for studies of flame chemistry. Mole fraction profile measurements for 24 flame species are presented for a fuel-rich low-pressure premixed laminar C3H8/O-2/Ar flame. Near-threshold photoionization efficiency measurements provide selective detection of individual isomers and unambiguous identifications of other flame species of near-equal mass. The absolute molar composition of the allene and propyne isomers Of C3H4 was determined. Absolute cross-sections for photoionization of C2H2, C2H4, CH3OH, C3H4 (propyne), CH3CHO, (CH3)(2)CO, and C6H6 were used to determine molecular beam mass discrimination factors valid for ion masses ranging from 26 to 78 amu.
