Diode-array spectrometer (DAPS) for visible and near-IR absorption measurements with 10-ns time resolution. Sedlmair, Josef; Ballard, S. Gwyn; Mauzerall, David C. (Rockefeller Univ., New York, NY 10021, USA). Rev. Sci. Instrum., 57(12), 2995-3003 (English) 1986. CODEN: RSINAK. ISSN: 0034-6748. DOCUMENT TYPE: Journal CA Section: 73 (Optical, Electron, and Mass Spectroscopy and Other Related Properties) Section cross-reference(s): 74 A diode-array pulsed spectrometer (DAPS) is described that performs flash photolysis studies with a time resoln. of 10 ns and a spectral resoln. of 2.4 nm over a 600-nm wavelength window in the range of 350-1100 nm. It employs a 1024-element photodiode-array detector with high dynamic range and low noise. Laser-pumped fluorescent dye mixts. are used as a novel, stable light source which enable it to record spectra with a photolimited signal/noise (S/N) ratio equiv. to 0.001 abs. units in a single shot. The measuring light distribution can be tailored so that a const. S/N ratios across a spectrum is attainable even in regions of high absorbance. Elec. artifacts from the actinic laser or other discharges do not interfere with the measurement and the effects of scattered actinic light and fluorescence from the sample are minimized. The instrument is simple to build, using mainly std. 92-71-7 and 19125-99-6 are just another two chemicals used in this study. lab equipment and easy to maintain and operate. .
