Near infrared spectroscopy: the practical chemical imaging solution

Frederick W. Koehler IV, Eunah Lee, E. Neil Lewis

Chemical imaging spectroscopy is an exciting new analytical advance that answers commonly asked questions such as what chemical species are in a sample, how much of each is present, and most importantly, where are they located? Through the fusion of traditional infrared spectroscopy with powerful microscopic and macroscopic imaging capabilities, chemical imaging spectroscopy answers all these questions simultaneously, in a single rapid measurement.

Changing scales with Fourier transformation [Lesson 3 of matrix algebra (matrix multiplication)]

A.M.C. Davies, Tom Fearn

In the last column, we showed how we could perform Fourier transformation (FT) of a near-infrared (NIR) spectrum in a few lines of matrix algebra and said that in this column we would use it in a novel way. The task we are going to perform is that of changing scales of spectroscopic (NIR) data. This may be novel, we are not aware that anyone else does it this way, but of course instrument manufacturers sometimes like to be silent about the methods they employ.

More reference spectroscopic data on the Internet! FTIRsearch Nicolet/Galactic Industries new joint venture

Antony N. Davies

A new joint venture between Galactic Industries and Nicolet has further added to the list of innovation in reference spectroscopic data delivery. The internet service running under http://ftiresearch.com was launched on 17 April 2000. With this new service coming on-line, the spectroscopist must now regard the year 2000 as one of the best for the introduction of new strategies and options for reference database access and service ever!

The TDeious way of doing Fourier transformation (Lesson 2 of matrix algebra)

A.M.C. Davies, Tom Fearn

At the end of the last column we promised that this time we would show how matrix algebra can be used for real computational tasks. The chosen task is Fourier transformation (FT) of a near infrared (NIR) spectrum. Those who know Tony Davies will not be surprised at this choice of subject but in the third lesson the reason for wanting to do the obvious will become apparent.
