FTIR Academy Showcase

Here you can find everything FTIR, from the most basic (what do “FT” and “IR” mean?) to applications using hyphenated techniques, like TGA-IR. Along the way, you can find information on sample preparation for transmission experiments, the power of FTIR Microscopy and charts relating chemical structure to the infrared spectrum. Come back often, as this content is being updated continually.

FTIR subtopics

FTIR Basics

Your starting point for learning about FTIR, this section covers what “FTIR” stands for and how it works. We also introduce the main sampling techniques and provide a more extensive overview of how they can be used to answer your questions.

FTIR Sampling Techniques

An in-depth training section, this will cover transmission, reflection, DRIFTS and ATR accessories, their use and care. The reasons for choosing one or the other method will become clear, and the strengths of each method will be highlighted. Stress here is on sample preparation and experiment optimization.

FTIR Applications

This area contains a lot of content, from webinars and videos to application notes. A wide breadth of applications in FTIR will be found, basic to advanced, and more technical content covering instrument performance and operations. You will find considerable content about FTIR Microscopy in this section as well.


Our market leading expertise in FTIR and FTIR Microscopy is not just about the instruments, but it is due to our wide experience and knowledgeable staff. We have gathered here many of the questions we have been asked, and will add to this section frequently.
