Our laser flash photolysis units are employed in various kinetic studies.  The unit shown here is our old nanosecond kinetic unit.  The laser is in the back, and from right to left are the UV-vis flash lamp, the reaction chamber, the monochromator, the photomultiplier tube, and the oscilloscope.  The entire unit is controlled by computer.  This unit can be used for studies of reactions with millisecond to nanosecond lifetimes.  A newer nanosecond unit has the same capabilities and also incorporates a stop-flow mixing unit for stopped-flow kinetic studies and "stopped-flow mixing, laser initiated" kinetic studies.  Faster processes are studied with a picosecond laser kinetic unit.

One of the GCs and the GC-MS are shown at the right.  The GCs are automated with a 100 carousal injector, but nobody uses it.  The GC-MS features Chemical Ionization in addition to EI.

A state-of-the-art diode array UV-visible spectrometer is shown here.  It is the small unit on the right of the picture.  In addition to standard spectroscopy, the spectrometer includes a stopped-flow mixing unit that allows sub-second mixing and kinetic studies.  The kinetic capabilities of the spectrometer complement the fast stopped-flow kinetic capabilities of the larger laser flash, stopped-flow spectrometer and offer the advantage of providing the entire spectrum in sub-second temporal resolution.
