Problems with FT-IR Spectra and How to Avoid Them

COURSE DESCRIPTION: Users of FT-IR spectrometers may have received little or no formal training in spectroscopy and therefore cannot distinguish between “good” and “bad” spectra. In this course, we will show many of the problems that are commonly encountered with FT-IR spectra measured by inexperienced (and often experienced!) users and show how to avoid them. Problems can appear from the instrument, the sample accessory and/or presentation. Since the bulk of the samples that are currently analyzed are done by Attenuated Total Reflection we will cover it in detail. We will also address common problems associated with other accessories. This year we will also be including a “tricks of the trade” component to the class.
TARGET AUDIENCE: This course is designed for scientists and engineers running infrared spectra who want to understand what constitute good spectra and how to achieve that using a variety of sampling techniques. It is particularly aimed at those students who are not familiar with all the sampling techniques available and how they impact the quality of the spectrum.
LEARNING OBJECTIVES: In this class students will learn the practical side of FT-IR including instrument effects, environmental effects, how to sample properly and data treatments.
