Learn how to use FTIR to solve on-the-job problems quickly and efficiently. Anyone who performs chemical analysis needs to know about FTIR. Regardless of which industry you work in, if you need to identify the molecules in a sample, you will benefit from this course. If you already use FTIR, you will see how to perform your analyses faster and cheaper and learn to optimize spectral quality while minimizing analysis time.
* How an FTIR works.
* The advantages and limitations of FTIR.
* Ways to measure instrument performance and spectral quality.
* How spectral subtraction and library searching make the analysis of mixtures easier.
* How to choose the right sample preparation technique for every sample.
* Which sampling techniques are fastest and easiest for given samples.
* How infrared microscopes have greatly expanded the applications of FTIR.
* Discover how ATR (Attenuated Total Reflectance) practically eliminates sample preparation for most samples.
Session titles
Day 1
* The Basics of FTIR
* How an FTIR Works -- Infreometers and interferograms; how a spectrum is obtained; optimizing resolution and minimizing noise; FTIR hardware: sources, detectors, beamsplitters, and lasers; measuring spectral and instrument quality.
* Spectral Manipulations: Handling Mixture Spectra -- The laws of spectral manipulation; spectral subtraction; library searching.
* Infrared Microscopes -- How an Infrared microscope works; preparing samples; applications.
Day 2
* Overview of IR Sample Preparation Techniques
* Transmission Sampling for Solids -- KBr pellets; Nujol mulls.
* Transmission Sampling for Polymers -- Casting films; the heat and pressure method.
* Transmission Analysis of Liquids and Gases -- Capillary thin films; sealed liquid cells; gas cells.
* Diffuse Reflectance (DRIFTS) Analysis of Powders and Solids -- Sample preparation; applications; abrasive sampling.
* Attenuated Total Reflectance (ATR): A Technique for Many Samples -- Accessory design; variables affecting depth of penetration; applications.
* Sample Preparation Workshop Experiments -- KBr pellet analysis of an aspirin tablet; DRIFTS and abrasive sampling of solids; capillary thin films: the easy way to analyze solids; ATR spectra of aqueous solutions, semi solids, polymers, and powders.
