This product is a 10mm far UV quartz fluorometer cuvette with polished faces at 90°, filled with ultra-high purity water and permanently sealed by heat fusion. It serves as a reference material for evaluating the signal-to-noise ratio (SNR) of a spectrofluorometer near its detection limit, effectively indicating the instrument’s ultimate sensitivity.
Unlike traditional methods using dilute fluorophore solutions, which are challenging and prone to contamination at low concentrations, this reference employs the phenomenon of Raman scattering. When excited by UV or visible radiation, pure water produces a characteristic Raman peak due to Stokes Raman scattering at a lower energy (longer wavelength). The resulting signal levels are exceptionally low and comparable to those from trace analyte concentrations, making it ideal for sensitivity qualification.
