Videos: FTIR Sampling Using ATR

This three-part video series teaches the basics of the most common FTIR sampling technique: Attenuated Total Reflection (ATR).

7-Minute Video: The Basics of The Attenuated Total Reflection Technique

This is the first video in a series that teaches the basics of the most common FTIR sampling techniques: Attenuated Total Reflection (ATR). How do people use ATR and why? Find out in this classroom-style instruction video. In less than seven minutes, I’ll show you how infrared light moves through diamond and germanium crystals, what affects the depth of penetration can have on the sample, and the most critical things to consider when choosing between crystals.

Which crystal should you use for Carbon Black Rubber? View the ATR-Basics video and find out.

3-Minute Video: The ATR Sample Preparation

This is the second video in a series that teaches the basics of the most common FTIR sampling techniques: Attenuated Total Reflection (ATR). This video addresses ATR accessories and sample preparation. Get a close-up view of the diamond crystal, pressure anvil, and gasket in an FTIR instrument, and learn how they are used to analyze samples.

In less than four minutes, I will show you how the various components of an ATR accessory and explain how they aid in analyzing samples.

What would happen if you tried to run a black rubber ring sample on the diamond crystal? View the ATR-Sample Preparation video and find out.

6-Minute Video: The Basics of The Attenuated Total Reflection Technique

This is the third video in a series that teaches the basics of the most common FTIR sampling techniques: Attenuated Total Reflection (ATR). This video addresses ATR data collections. See various samples, including solids and liquids — being analyzed in real time with an FTIR instrument, and see the analysis results in seconds.
