Flash photolysis spectrometer
Kronos from Ultrafast Systems (Sarasota, FL) is an inexpensive miniature flash photolysis spectrometer designed to introduce chemistry students to the principles of chemical kinetics using time-resolved spectrometry. With Kronos, students can quickly and easily generate reaction time profiles and thence perform kinetic analysis of a variety of transient species such as free radicals, excited states, metal-coordination complexes in unusual valence states, and the like. The Kronos patent pending design utilizes a Xe arc flash lamp as an excitation source, which allows for wavelength tunability.
