Prinzip der Methode Die Massenspektrometrie ist eine Methode zur Bestimmung der Molekulmasse freier Ionen im Hochvakuum. Ein Massenspektrometer besteht aus einer Ionenquelle zur Erzeugung gasformiger Ionen, einem Massenanalysator, der die Ionen nach dem Verhaltnis der Masse zur Ladung (m/z) trennt und dem Detektor zum Ionennachweis. Die Einfuhrung der Probe in die Ionenquelle erfolgt direkt oder uber on-line-Kopplung mit einem Gaschromatographen bzw. einer HPLC-Anlage. Im Ergebnis wird ein Massenspektrum erhalten: Die Darstellung der vom Detektor registrierten relativen Ionenhaufigkeit uber...

Working in the lab, but unsure what your results actually mean? Would you like to know how to apply trueness tests, calculate standard deviations, estimate measurement uncertainties or test for linearity? This book offers you a problem-based approach to analytical quality assurance (AQA). After a short introduction into required fundamentals, various topics such as statistical tests, linear regression and calibration, tool qualification or method validation are presented in the form of exercises for self-study. Solutions are provided in a clear step-by-step manner. Interactive Excel-sheets...
