SAMPLE PREPARATION TECHNIQUES IN ANALYTICAL CHEMISTRY

In the past three decades there have been major advances in our understanding
of the chemistry and function of nutritional components. This has
been enhanced by rapid developments in analytical techniques and instrumentation.
Chemists, food scientists and nutritionists are, however, separated

1.1 What This Chapter Should Teach You
 To understand that chemical measurements are made for a
purpose, usually to answer a nonchemical question.
 To define measurement and related terms.
 To understand types of error and how they are estimated.
 What makes a valid analytical measurement.

the data are normalized by assigning the most intense peak (denoted as base peak) a value of 100.Other peaks are reported as percentages of the base peak.A very good general survey for interpreting mass spectral data is given by Silverstein et al.1810.6.1 Initial Steps in Elucidation of a Mas[r]

Most analytical experiments produce measurement data which require
to be presented, analysed, and interpreted in respect of the chemical
phenomena being studied. For such data and related analysis to have
validity, methods which can produce the interpretational information
