This note gives
a fairly accessible introduction to the principles and applications of mass
spectrometry. It starts by outlining important topics, such as sample
introduction, ionization techniques (electron and chemical ionization), and mass
analyzers. It then discusses the different types of detectors and the vacuum
systems required for successful analysis. It offers a tutorial overview of how
mass spectrometry can be applied to the analysis of complex chemical systems,
including an introduction to data systems and interpretation techniques. This
note is perfect for newcomers in the analytical chemistry arena seeking to get a
good grasp of the basics of mass spectrometry.
This is a comprehensive note on
X-ray spectroscopy techniques, aimed at detailing their applications in
different fields, with an emphasis on the special applications in nanoparticles
and molecular mechanisms. It begins with the introduction of XRF processes and
techniques followed by high-resolution X-ray spectroscopy using compound
semiconductor detectors and digital pulse processing systems. It also includes
analytic applications of X-ray techniques, including dispersive X-ray
spectroscopy as well as quantification in X-ray fluorescence spectrometry. In
addition, it approaches specialized uses such as time-resolved X-ray absorption
spectroscopy in the study of metalloproteins and the application of soft X-rays
in astrochemistry. The note concludes discussing nanoscale chemical analysis
that highlights energy dispersive X-ray spectroscopy (EDX) and transmission
electron microscopy (TEM) with relevance to the characterization of interfaces
and materials on the nanoscale.
