Fourier Transform Infrared Spectroscopy: A Hands-on Workshop


  • Learn many "tricks of the trade" that only experienced hands-on users know.
  • Understand how to increase efficiency by using the proper instrument settings and sampling techniques the first time you analyze a sample.
  • Learn 15 experimental pitfalls to avoid during quantitative analysis.
  • Discover nine new FTIR techniques that can solve many industrial problems.
  • Learn quick and easy methods to access data quality and instrument performance.
  • Topics

  • How an FT-IR Works—understanding the Michelson interferometer; how an interferogram becomes a spectrum; determining resolution/tradeoffs between resolution and signal-to-noise ratio; hardware considerations: sources, detectors, beamsplitters, etc.; spectrometer electronics; measurements of data quality.
  • Proper Use of Spectral Manipulation—spectral subtraction; baseline correction; smoothing; spectral derivatives; deconvolution; library searching; band fitting.
  • Choosing the Right Sampling Technique—transmission techniques; reflectance techniques; attenuated total reflectance; photoacoustic spectroscopy.
  • Quantitative Analysis—Beer's Law and single component analysis; common experimental pitfalls to avoid; multicomponent analyses.
  • "Hyphenated" Infrared Techniques—infrared microspectroscopy; gas chromatography-FTIR spectroscopy; high pressure liquid chromatography-FTIR (HPLC-FTIR); FT-Raman spectroscopy.
  • Applications Using Advanced FTIR Instrumentation—novel interferometer designs; applications of dynamically aligned interferometers; theory and applications of step scanning; hardware for other spectral ranges.
  • New and Unusual Sampling Techniques—infrared fiber optic spectroscopy; infrared emission spectroscopy; far infrared spectroscopy.
  • Thermal Techniques Interfaced to an FTIR—thermo-gravimetric analysis—FTIR; differential scanning calorimetryFTIR.
  • On-line Process Monitoring FTIR—technical difficulties; instrumentation and sampling; applications.
  • Intended Audience
    Chemical scientists or technicians who work in the fields of analytical, organic, polymer, rubber, forensic, and quality control chemistry. The course is designed for anyone who uses FTIR to discover molecular composition and the quantities of molecules in a sample. Prior experience is helpful but not required.

    This course can be adjusted to meet your specific training requirements. The course can also be combined with a mentoring program and other consulting services to help your company quickly and productively achieve self-sufficiency.

    Dr. Brian Smith is a principal of Spectros Associates.
