Infrared (IR) spectroscopy, known to many people who use it as Fourier Transform Infrared Spectroscopy (FT-IR) because FT-IR instruments are the most common type of instrument design, is a very powerful approach for both determining the identity of materials and quantifying components in a mixture. Coupled with ATR (attenuated total reflection) as the sampling approach it becomes very easy to obtain spectra from a sample. But these techniques only work if the operator understands the abilities and limitation of both the instrument and the sampling approach. We will discuss some of the benefits and pitfalls of FTIR, and how to address three common types of problems which are:
- Problems that result from the instrument itself
- Problems that can occur from the sampling accessory
- Problems introduced by the sample itself
Benefits of taking this course
► Understand the impact of the infrared sampling approach on the spectrum.
► Learn some “tricks of the trade” not discussed in text books or instrument manuals
► Be able to recognize spectral artifacts that might be due to the instrument, sample or inadvertent contamination
About Ellen Miseo
Ellen V. Miseo, Ph.D. has been involved in vibrational spectroscopy and instrument development her entire career. Originally trained as a physical chemist her primary interest is in new applications of spectroscopic techniques and infrared imaging. She has worked for instrument companies as well as run laboratory operations during her career in both the food and material science areas. Most recently she is the Chief Technical Officer for TeakOrigin, Inc. whose mission is to use spectroscopy in the food supply chain to determine quality and authenticity.
Dr. Miseo is actively involved in a number of professional societies related to spectroscopy. She is currently the president of the Coblentz Society and served as the President elect, President and Past President of the Society for Applied Spectroscopy between 2015 and 2017. She is also a member of the American Chemical Society. She received her BS in chemistry from St. Francis College, Brooklyn, NY and her Ph.D. in Physical Chemistry from Polytechnic Institute of New York, now part of NYU.
