Spectros Associates Proudly Presents the One Day Short Course
Infrared Sample Preparation
Instructor: Dr. Brian C. Smith
A 1-day overview of how to prepare samples for infrared analysis. The first part of the course is a detailed look at the wide variety of infrared sampling techniques. The second part of the course is a hands-on sample preparation workshop using real FTIRs and sampling accessories. You will learn how to prepare solids, powders, liquids, semi-solids, pastes, gels, polymers, and gases for IR analysis. Sample preparation is half the battle in obtaining good spectra, learn to win that battle!
Wrap-up. Time for individual consultations and questions.
