Introduction

In my last column I began a revision of basic chemometrics.1 In this column I will discuss some interpretation of the results produced by principal component analysis (PCA) as part two of this revision programme.

PCA is a mathematical method of reorganising information in a data set of samples. It can be used when the set contains information from only a few variables but it becomes more useful when there are large numbers of variables, as in spectroscopic data.

The International Spectroscopic Database (IS-DB) went live on 19 May 2003. Following over seven years fighting for funding and receiving the EU EuroSpec grant1 in 2002 the team are pleased to announce that the first version of the international digital archive for spectroscopic data was switched on for data deposition in May.
