Pulse Radiolysis Laboratory pulselab@orange.ichtj.waw.pl

Head: Prof. Krzysztof Bobrowski

Time-resolved pulse radiolysis set-up equipped for optical absorption spectroscopy allows direct observation of fast chemical events induced in condensed media and involving short-lived intermediates. Its time resolution of 0.5, 2.5 and 5.5 µs is dependent on pulse duration. Detection system includes 150 W xenon lamp (as analytical light source), various types of irradiation cells, monochromator, photomultiplier, and the data acquisition system. The analog signal is converted to digital signal by Tektronix TD620 and Iwatsu TS-8123 oscilloscopes and transfered to the PC computer for data collection and further processing. The pulse radiolysis measurements are possible over 250 - 1000 nm wavelength range and over 5 to 50 Gy dose range. Pulse radiolysis process, i.e. triggering sequence of measurements, setting wavelengths, and acquisition parameters, is computer-controlled.
