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
