The role of the analytical chemist has not changed since the inception of the discipline. However, the questions for which society wants answers have become more challenging. Instrumental analysis has continually evolved to keep up with the analysis demands, but sample preparation has failed to keep up with the evolutions of modern trace organic analysis instrumentation. In this book we discuss the importance of sample preparation for trace organic analysis. Part I focuses on the fundamental theory of extracting an analyte from a sample matrix, modern extraction techniques, and post extraction processing. Part II reviews modern instrumental analysis techniques as they relate to the sample preparation process and Part III discusses how advances in microwave technology bring sample preparation to the same standards as instrumental techniques. The goal of the authors was to produce a text that helps today’s trace organic analyst understand and overcome the difficulties of sample preparation by learning how to THINK GREEN.

Joaquim A. Nóbrega received his Ph.D. from the State University of Campinas in 1992 and completed his postdoctoral training with Prof. Ramon Murray Barnes (University of Massachusetts, Amherst, MA, 1996) and with Prof. Bradley Todd Jones (Wake Forest University, Winston-Salem, NC, 2003). He is a Full Professor at the Department of Chemistry, Federal University of São Carlos (São Carlos, São Paulo State, Brazil) and is a Visiting Professor at the Faculty of Pharmacy, University of Concepción (Concepción, Chile). His main research interests are sample preparation in inorganic analysis, atomic absorption spectrometry, atomic emission spectrometry, and inductively coupled plasma mass spectrometry. He is a member of the Group for Applied Instrumental Analysis since its beginning in 1994. He has recently started the Institute GAIA of Spectrometry for increasing interaction with professionals working
with sample preparation and inorganic analysis using spectrochemical methods with emphasis in inductively coupled plasmas.
Camillo Pirola is the Marketing and Business
Development Manager at Milestone. After
receiving his degree in Chemistry, in May 1999,
Camillo joined Milestone as an Application
Chemist. His professional career interlaces with
Milestone’s overall growth. He then became
Application Manager, providing application
support to all Milestone distributors around the world. In the late 90’s,
he became Area Manager for several countries including Japan, Italy,
The United Kingdom, Spain, Russia, India, and Brazil. While retaining
his position of Area Manager, in the mid-2000’s, Camillo became
responsible for the Milestone marketing at a global level. Since
2012, he is also the Business Development Manager at Milestone.
Camillo has contributed to several scientifi c papers and lectures, and
is often invited to give presentations, seminars, and training courses
