In Chapter 4, titled Principles of Mass Spectrometry Imaging Applicable to Thin-Layer Chromatography, the authors first introduce a budding analytical approach known as imaging mass spectrometry (IMS) strategy and then present some successful examples of its practical applications. Then, they introduce in detail three mass spectrometric techniques as those routinely used within the framework of IMS. These are secondary mass spectrometry (SIMS), matrix-assisted laser desorption/ ionization (MALDI-IMS), and desorption electrospray ionization (DESI). Finally, the authors discuss the advances and bottlenecks of these techniques when applied to TLC. [Pg.8]

In addition to these characterization tools, surface analytical techniques such as surface matrix-assisted laser desorption ionization (Surface MALDI) mass spectrometry, Rutherford backscattering spectroscopy (RBS), and near-edge X-ray absorption fine stmcture spectroscopy (NEXAFS) are used to obtain structural and chemical details about surface thin films. Surface MALDI, also known as MALDI-ToF MS (see Section 5.4.2), offers high mass resolution for analyzing surface films and molecular layers using the m/z of various ions generated from the sample surface (mixed with an... [Pg.101]
