About This Product

In many light-related phenomena, intermediates (transient species) that are created and destroyed instantaneously play an important role in determining the products and reaction efficiency. Multiple of these intermediates exist in a single reaction system, and the observed time scales and wavelength ranges differ. picoTAS+TCSPC uses two methods, transient absorption method and fluorescence lifetime method, to observe optical absorption and emission signals of intermediates over a wide range of both time and wavelength, and is useful for research on various fast reactions and high performance. Contribute to device development.

■Features of picoTAS+TCSPC

・In-house developed RIPT method and TCSPC method combined into one device ・Compact design, no optical bench required (-ns model)

■Features of picoTAS

・Transient absorption measurement from 100 picoseconds to milliseconds ・Wide measurement wavelength range from visible to near infrared ・Remove emission signal and measure pure transient absorption

■Features of TCSPC

・Easy to switch from transient absorption measurement mode ・Fluorescence excitation is possible at any wavelength (when the repetition period is fixed at 50ns (=1/20MHz))

■What is transient absorption spectroscopy?

・High-speed measurement of changes in absorption (absorbance) ・Detection and identification of short-lived intermediates (transient species) ・Both luminescent and non-luminescent intermediates can be detected ・Able to track and analyze complex reaction processes

■What is TCSPC fluorescence lifetime method?

・High-speed measurement of changes in luminescence ・Detection and identification of luminescent excited species ・Calculate life with high sensitivity and precision using single photon counting
