| Definition | The Seapoint Rhodamine Fluorometer (SRF) is a high-performance, low power instrument for in situ measurements of Rhodamine WT (a fluorescent, xanthene dye, that is often used as a hydrologic tracer). The instrument can be moored, towed, used in profiling mode or used to make in-line measurements. Typical applications include: Dye Trace Studies, Mixing and Dispersion Studies, Leak and Spill Detection, Flow Measurement, and Reverse Osmosis Recovery Measurement. The SRF uses modulated green LED lamps and a narrow-band excitation filter to excite Rhodamine WT. The fluorescent light emitted by the Rhodamine WT passes through an orange emission filter and is detected by a silicon photodiode. The low-level signal is then processed using synchronous demodulation circuitry which generates an output voltage proportional to Rhodamine WT concentration. The instruments excitation wavelength is 540 nm Centre Wavelength (CWL), or 20 nm Full Width at Half Maximum (FWHM). The minimum detectable level is 0.02 micrograms per litre of Rhodamine WT. The instruments operating temperature range is between 0 degrees Celsius and 65 degrees Celsius. The instrument is depth rated to 6000 meters. | ||
