TSP-1000 is a laser flash photolysis system for the measurement of transient absorbance. There are many uses in the analysis of the elementary processes of photochemical reactions. With a nanosecond pulsed laser as the exciting light source, this system measures transient UV-VIS absorption in a broad range from nanosecond to millisecond.
Data are acquired by the combination of a photomultiplier detector and a digital oscilloscope in the single-wavelength monochromator system, and by the combination of a photodiode array detector and a high-speed AD converter in the multi-channel spectrophotometer system. In both systems, time resolution up is available to 10 nsec.
