About the Course

Learn how to use FTIR to solve on-the-job problems quickly and efficiently. If you already use FTIR, find out how to perform your analyses faster and cheaper, and learn how to optimize spectral quality while minimizing analysis time.

Topics include:

  • The advantages and limitations of FTIR,
  • How an FTIR works,
  • Ways to measure instrument performance and spectral quality,
  • How spectral subtraction and library searching make the analysis of mixtures easier.

What You Will Learn

  • Understand how to measure instrument performance
  • Improved ability to analyze mixtures to identify molecules in samples
  • Quickly solve on-the-job issues

Who Should Attend

  • Anyone who performs chemical analysis.
  • Scientists and technicians who want to make their FTIR analyses faster, better, and cheaper.
  • Managers who want cost-effective infrared analyses.
  • Anyone who needs to identify molecules in samples.

Prior experience with FTIR is helpful, but not necessary.
