Wilfried M A Niessen is an analytical chemist with 34 years of experience as a researcher and project manager in the field of principles, instrumentation and applications of liquid chromatography-mass spectrometry. As a consultant for hyphen MassSpec, he provided over 400 courses in more than 15 countries, as well as many consultancy projects. He was extraordinary professor bioanalytical mass spectrometry at VU University Amsterdam. He is the (co)author of more than 210 publications; over 40 book chapters; 6 books and guest-editor for 6 special volumes on mass spectrometry topics published by the Journal of Chromatography A. Ricardo A Correa C is an organic chemist who has been involved with mass spectrometry for 25 years. He runs Trans-Laboratory, a chemical analysis service provider, offering course cycles around Europe on analytical chemistry where GC-MS and LC-MS play a central role. He has developed applications which have been presented in scientific meetings in Belgium and The Netherlands, as well as coordinated the set-up of analytical chemistry laboratories overseas. He is the co-author of publications for reputed chemistry journals such as the Journal of the American Chemical Society, the Journal of Organic chemistry, the Journal of Chromatography A.
