peaks in this series are of lower intensity and are observed up to m l z in 850. Two other sets of peaks observed in Figure 8b cannot be rationalized as arising from the ions produced by simple bond cleavages of Fomblin Z. These peaks have a spacing of m / z = 166, and their mlz values coincide with the two most intense Krytox series D-2 -[FRJ and N = [OR,CF,CFJ. They are attributed to Krytox impurities in the sample and are labeled D and N in the spectrum of Figure ab. SUMMARYIn summary, the TOF-SIMS spectra were obtained from thin films of Krytox and Fomblins Y and Z up to mlz = 6500.The fragmentation patterns were rationalized on the basis of the known structures and stabilities of the observed ions. Cationized Krytox oligomers were observed along with Krytox fragments. The fragmentation in the spectra of copolymers Fomblin Y and Z is complicated, and often several ion structures can be assigned to a given peak. The fragmentation patterns are unique for each kind of PFPE and are reproducible, independent of sample preparation and substrate. Several important points are demonstrated by this study.First, fragment ions of m / z > 300 in the perfluoropolyethers have intrinsic charge without cationization, unlike most other polymers. Second, quality spectra can be obtained from films ca. 1000 A thick, but these spectra contain peaks only due to fragment ions. Cationized oligomer ions occur only from films in the range of monolayer coverage. This demonstrates the importance of cationization for obtaining spectra from thick polymer films. Third, the study demonstrates the utility of TOF-SIMS for the structural characterization and the oligomer analysis of thin films of low molecular weight perfluorinated poly-and copolyethers.

This paper is a presentation of recent key developments in quadrupole ion trap mass spectrometry. These key developments have been made in three areas; namely, the trapping of ions generated externally to the ion trap, the fine control of the trajectories of ions confined within the ion trap, and the ejection of ions from the ion trap. Applications of quadrupole ion trap mass spectrometry that are illustrative of these developments are discussed. The origin of the quadrupole ion trap and its mode of current usage are discussed briefly. # 1998 John Wiley & Sons, Ltd. Received 20 June 1998; Revised 7 August 1998; Accepted 9 August 1998 The original commercial usage of a quadrupole ion trap was limited to the formation of ions in situ by electron impact ionization, focusing of the nascent ions to a cloud at the centre of the ion trap, and mass-selective axial ejection of ions to form a mass spectrum. The sheer simplicity of the mass-selective axial ejection technique permitted the commercialization of the quadrupole ion trap as a massselective detector for compounds separated by gas chromatography. In the past 15 years, the field of quadrupole ion trap mass spectrometry has developed appreciably; while it is not possible to consider all developments, attention can be focused on the key developments that extend or enhance ion trap performance markedly. The key instrumental developments cover three main areas: (a) the injection and storage of ions generated externally to the ion trap; (b) the fine control of the trajectories of ions confined within the ion trap; (c) the ejection of ions from the ion trap.
