KRONOS - Portable Microsecond Flash Photolysis Spectrometer


Kronos is a portable flash photolysis spectrometer designed for transient absorption and emission measurements on the microsecond and longer time scale. Kronos can measure solid and liquid samples in the transmission as well as the reflection mode. The Kronos patent pending design utilizes a Xe arc flash lamp as an excitation source, which allows for wavelength tunability. The photoinduced transient species are investigated by passing the output of a white light emitting diode (LED) through the sample. Using an LED as a probe light source results in superior stability and low noise. The probe wavelength range of Kronos is 425-700 nm. After traveling through the sample, the probe light passes through an interference filter. After that a 10 nm wide section of the spectrum is delivered to the detector photodiode. The detector voltage output is digitized and transferred to a PC for generation of a kinetic trace and for further manipulations
