An Introduction to Ion Chromatography

May 15-16, 2001

Since its introduction in 1975, Ion Chromatography has progressed to be a very powerful analytical tool. This IC course will explore in detail the principles of the technique and will highlight specific and diverse application areas. Several IC systems will be available for demonstration.

Course Outline
