Analytical testing techniques are used by a variety of different industries to uncover contamination or quality issues, as well as reveal a sample material’s composition to further the development of their products.
Below we’ve compiled a handful of analytical testing videos that show analytical testing techniques in action, so you can learn more about the basics of how they’re conducted and interesting ways in which they’re used.
The Basics of Analytical Testing Techniques
Introduction to Analytical Chemistry
What is analytical chemistry? What are some of the techniques in chemical analysis? When and where are these techniques used? The video below answers all these questions and more in under three minutes.
An Introduction to FTIR
Fourier transform infrared spectroscopy (FTIR) analysis is an analytical testing technique that is used to identify organic and some inorganic materials based on their absorbance of infrared light. Its speed and accuracy often makes it a popular first step in identifying the composition of materials.
In this video, Dr. Jay Ratliff dives into the basics of this technique, including examples and diagrams to make it easy to follow along.
Understanding the Basics of Chromatography
Chromatography is the overarching term for various laboratory techniques that separate compounds or components. In this video, Angela Guerrero gives an overview of eight different techniques.
Analytical Techniques in Action
Identifying the Chemical Composition of Drugs with GC/MS
Gas chromatography mass spectrometry, or GC/MS, is a materials analysis technique that is used to separate, identify and quantify all the compounds within a sample—making it an ideal technique for uncovering exactly what’s in various drugs.
In the video below, Dr. John Ramsay of TICTAC shows you the GC/MS process for identifying and quantifying what’s in a drug tablet.
Identifying Plant Diseases and Soil Deficiencies with FTIR
At Mississippi State University, a team of researchers has used FTIR to create a database of fungi, plant, and soil samples, with the goal of using that database for identifying plant diseases and soil deficiencies in the field—which could be a big help for the agriculture community.
