The ISS Chronos is the first, frequency-domain fluorescence lifetime instrument based on the use of laser diodes and light emitting diodes (LED) as excitation sources. This powerful tool provides all the benefits of a full lifetime fluorometer at an affordable price. The ISS Chronos has been enhanced for those users operating at standard wavelengths of excitation typically at a set region. The Chronos is a fully-automated instrument using a Windows based software program and can be upgraded to steady-state acquisition.
