Spectrofluorometer Chronos DFD (ISS)
The Chronos DFD Fluorescence Spectrofluorometer characterizes the fluorescence properties of the analyte in solution. Characterization includes measurement of the stationary, polarized and time-resolved fluorescence. As a source of excitation light for the stationary and polarized fluorescence, the xenon lamp is used. A 370 nm laser diode and a 280 nm pulse LED are available for time-resolved fluorescence. A pair of PMT detectors are available to enable measurements in standard L-format and T-format geometry for fast and accurate polarization measurements. The instrument is capable of measuring in the wavelength range 200 nm to 900 nm and excited lifetime ranging from 10∙10−12 sec to 1 sec. in an adjustable temperature range from −30 °C to 105 °C (0.02 °C).
