“…C) and under a stream of helium. 29,30 Under these conditions, primary and secondary alcohols are converted into aldehydes and ketones, respectively, and tertiary alcohols remain unaffected or undergo dehydration. This enables primary, secondary and tertiary alcohols and dialkyl ethers to be distinguished.…”

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..

“…An efficient approach for the investigation of aliphatic, alicyclic and alkylaromatic alcohols within mixtures was based on their on-line dehydrogenation in a GC/MS system. 92 Conversion of alcohols to carbonyl compounds (in the case of tertiary alcohols, the reaction does not proceed or dehydration takes place) was accomplished in a microreactor (Cu-dust, 320°C) located before the injection port of the GC/MS system. The resulting carbonyl compounds were then separated and mass identified spectrometrically.…”

The present paper is complementary to the foregoing reviews and describes some additional methods of the derivatization of particular functional groups mainly to enhance the structural information content of electron ionization and chemical ionization mass spectra. Derivatization approaches for the modification of unsaturated compounds, alcoholic, carboxylic, carbonyl, amine and other functional groups, are discussed. Derivatization for separation and quantitative determination of chiral enantiomeric compounds is also considered. Preliminary chemical and physical-chemical degradation for structure elucidation of high molecular weight compounds (biopolymers, synthetic polymers) is mentioned. Chemical aspects of derivatizations and characteristic mass spectral features of derivatives are described briefly. Some particular applications of chemical modification, in conjunction with mass spectral measurements for the analysis of various important bioorganic compounds and compounds in biological fluids, air, environmental etc., are considered.

Was kann ein Chemiker mit ein paar Nanogramm einer wertvollen organischen Substanzrein oder unrein -anfangen? In jedem Fall eine ganze Menge, mu13 hier die Antwort lauten. Die Komponenten eines Gemisches kbnnen quantifiziert, getrennt, isoliert, durch Reaktionen abgebaut oder derivatisiert sowie extrahiert werden; auBerdem lassen sich Massenspektren aufnehmen. Wenn die Substanz nicht durch einen hohen Anteil an Losungsmittel verunreinigt ist, sind Manipulationen ohne grofleren Substanzverlust oder groBere Verdunnung moglich. Not macht eben erfinderisch. Die in dieser Ubersicht behandelten Beispiele zeigen, was heute in der Nanogramm-Chemie erreicht werden kann. Sie sollen als Anregurig dienen und d a m fuhren, neue Anwendungsmoglichkeiten zu entwickeln. Die Beispide stammen zwar zum groBen Teil aus der Insektenchemie, doch sei ihre allgemeine An wendbarkeit hier betont. Die vorliegende Ubersicht veranschaulicht, daB Gaschromatographie und Reaktionsgaschromatographie, jede fur sich oder in Kombination mit der Massenspektrometrie, in den Handen des Chemikers wertvolle Werkzeuge fur die Strukturaufklarung fliichtiger organischer Verbindungen sind, von denen nur Nanogramm-Mengen zur Verfiigung stehen.
