Course Description
This 1-day program is an intensive introduction to the properties and usage of light emitting diodes (LEDs) in chemical analysis and chemistry in general. The emphasis will be on practical issues and the applications of LEDs particularly for analytical optical methods (photometry, fluorimetry), optical detection in analytical flow-through methods (FIA, HPLC, CE), optical sensors, microfluidic chips, and in photochemistry. Examples of some elementary techniques used to characterise LEDs including measurement of emission spectra will be conducted as hands-on experiments.

Target Audience
This is an intermediate level course with respect to LEDs. However, the course is designed in such a way that a wide range of participants can benefit: those having already a considerable experience in their area, those beginning to use LEDs and having some experience, and scientists, engineers or lecturers just considering whether LEDs could be used in their work. The course is also suitable for persons involved in teaching in the area of instrumental analytical chemistry. The participants will benefit from some training and experience in chemistry and analytical chemistry in particular. Prior exposure to and use of other LEDs is useful but not expected.
