Hyphenated techniques, sample introduction spectrometry

Because ICP-MS with different instrumentations and sample introduction systems (besides solution nebulization, also laser ablation or hyphenated methods, such as HPLC, CE, SPME) is today the most frequently used analytical technique for precise and accurate isotope ratio measurements, the following section will mainly focus on this form of mass spectrometry with an inductively coupled plasma source. 

The book covers several subtopics of miniaturization and mass spectrometry. It combines (i) technological developments in the quest for miniaturization of sample preparation and how to connect micrometer-sized devices to a mass spectrometer, (ii) various illustrations of fields that benefit from such a hyphenated technique and (iii) technological developments for the miniaturization of the mass spectrometer. Additionally, the book is not restricted to one ionization technique as is often the case for many reviews, but it reports on efforts for both the ESI and MALDI ionization techniques. After an introduction to miniaturization and mass spectrometry, the book is divided in three sections that respectively concern (i) ESI-MS applications, (ii) MALDI-MS applications and... 

Each chapter provides a discussion of the fundamental principles underlying the techniques, descriptions of the instrumentation, and numerous applications. The chapters also contain updated bibliographies and problems, and most have suggested experiments appropriate to the techniques. This completely revised and updated edition covers subjects in more detail, such as a completely revised x-ray chapter, expanded coverage of electroanalytical techniques, and expansion of chromatography and mass spectrometry topics to reflect the predominance of these instruments in laboratories. This includes state-of-the-art sample introduction and mass analyzers and the latest developments in UPLC and hyphenated techniques. The book also contains new graphics and addresses several new topics ... 

ICP is seeing more use as a sample introduction system for various hyphenated techniques. New to the pharmaceutical industry is the use of inductively coupled plasma-mass spectrometry (ICP-MS). ICP-MS offers excellent versatihty and sensitivity to the analyst, and greatly complements any pharmaceutical... 

Four general classes of NMR experiments are routinely used to analyze metabolites (1) ID NMR experiments (2) 2D NMR experiments (3) Solvent suppression methods and (4) Hyphenated NMR experiments. The ID and 2D NMR experiments are commonly used for metabolite structure determination. The various solvent suppression techniques (Gaggelli and Valensin, 1993 Hwang and Shaka, 1995 Smallcombe and Patt, 1995) are crucial for dilute metabolite samples where the solvent peak is the most intense peak in the NMR spectrum. These solvent suppression techniques can be incorporated as needed in both ID and 2D NMR experiments. Since their introduction in the 1990s, hyphenated NMR methods have become common tools in the identification of metabolites. These methods include LC-NMR (Albert, 1995 Spraul et al., 1993, 1994), LC-NMR-MS (Mass Spectrometry) (Shockcor et al., 1996) and LC/SPE (solid phase extraction)/NMR (Alexander et al., 2006 Bieri et al., 2006 Xu et al., 2005 Wilson et al., 2006).
