“…Gas chromatographic analysis of the headspace above foods (Buttery and Teranishi, 1961;Nawar et al, 1960) has been applied to many products including orange juice (Bomben et al, 1966;Wolford et al, 1963). Also, there have been a few reports on combined gas chromatography-mass spectrometry (gc-ms) in which some or all of the samples analyzed were directly from headspace (Flath and Forrey, 1970;Heatherbell and Wrolstad, 1969;Heins et al, 1966;Issenberg et al, 1969;Morgan and Day, 1965;Nawar et al, 1969).…”

“…22 In addition, this approach differentiates between unsaturated and isomeric cyclic compounds. The efficiency of such a methodology was shown for the first time by Teeter et al 23 and Issenberg et al 24 who inserted a microhydrogenator between the GC column and mass spectrometer in the study of α-olefins and substituted cyclohexenols in mixtures. However, such a microreactor may be located ahead the gas chromatographic column.…”

“…For post-column conversion of olefins the same microhydrogenators may be used that have been described for pre-column modification. 25 As mentioned above, Teeter 23 and Issenberg 24 were the first to introduce a microhydrogenator between the GC column and mass spectrometer for the analysis of various unsaturated compounds. It is worth mentioning that post-column hydrogenation in GC/MS may also be accomplished in a tube prepared from hydrogen permeable alloy (for for example, Pt/Ir).…”

The review describes on-line derivatization/degradation methods employed in mass spectrometry to solve some structural and analytical problems. Advantages and applications of various positions of reaction systems connected mainly to a mass spectrometer or a gas chromatograph/mass spectrometer are considered. Among these are reaction systems connected directly to the mass spectrometer (reaction mass spectrometry, pyrolysis-mass spectrometry or direct pyrolysis-mass spectrometry); flash-heaters as reactors in gas chromatography/mass spectrometry (GC/MS); in-line chemical reactors located before the chromatographic column [pre-column derivatization/degradation with the use of catalytic reactions, pyrolysis (pyrolysis-GC/MS), degradation in elemental analyzers-isotope ratio mass pectrometry (EA-IRMS)]; on-column derivatization and deuteration; reactor located between the chromatographic column and a mass spectrometer [post-column catalytic derivatization, gas chromatograph-combustion-isotope ratio mass spectrometer (GC-c-IRMS)]. Post-column derivatization in high performance liquid chromatography/mass spectro-metry is briefly mentioned. Application of such on-line methodology to structure elucidation of low molecular mass compounds and polymers, to the determination of isotope ratios of the most common elements, to the investigation of catalytic reactions is discussed..

“…The electron energy was 70 eV and the total ion current chromatograms were recorded from a monitor located between the electrostatic and magnetic analyzers of the mass spectrometer. The GC-MS system used has been described in detail by Issenberg et al (1969). Identification of all compounds was confirmed by comparison with mass spectra and retention data of reference chemicals run under identical conditions.…”

The GLC retention data (Kovat's index 1523) were also consistent with those of an authentic sample of methylisoborneol. The concentration of methylisoborneol in the volatile oil was of the order of 0.4% and therefore of the order of 4 parts per 109 parts of the soil.Other components with earthy odors were detected but could not be characterized in the present work. A number of components with nonearthy odors were also characterized (mass spectrum and GLC retention data consistent with that of an authentic sample). These included benzaldehyde, camphor, hexanol, heptanol, and nonanol.How much of these compounds is normally transferred to vegetables has yet to be studied although geosmin has recently been characterized in beets (Aeree et al., 1976; Murray et al., 1975) and off-flavored dried beans (Buttery et al., 1976).
