Description

This text presents the information needed to design a successful quantitative analysis using mass spectrometric techniques currently available and widely employed. It is devoted to the researchers of different areas, who use mass spectrometry as a detector suitable for the measurements of their interest.
  • An essential book for the practicing mass spectroscopist
  • A genuine 'how-to' text for the practitioner focusing on quantification rather than instrumental design and techniques
  • Up-to-date structured text describing methods, experimental strategy, capabilities and limitations, with data analysis and interpretation
  • Brings together material widely dispersed in the pertinent literature into one unique source
  • Internationally recognized group of authors
