Times of fluoridated meters with semiconductors and its use

摘要

A spectrofluorimeter uses a triggered xenon flash tube (14) which is powered with a capacitor store and controlled by program instructions from a microcontroller. The spectrofluorimeter uses an optical cell (12) having a configuration in which the xenon flash tube (14) is placed in spaced relation to a pair of signal detectors (17, 19) and a reference detector (21). The spaced relation of these components allows the use of solid state detectors (17, 19, 21) in the spectrofluorimeter. Electrical isolation of the detector amplifiers is provided during all periods except for the actual detection portion flash cycle using the microcontroller. The spectrofluorimeter has a solid state detection capability that can be used effectively for the detection of visible wavelengths using commercially available fluorophores.
