This Reference Material consists of 10 mm far UV quartz fluorometer cuvettes with polished faces at 90°, containing Quinine Sulfate dissolved in perchloric acid and permanently sealed by heat fusion. It is supplied either with or without a perchloric acid blank, and is also available as sets of solutions with concentrations up to 1.0 mg/l for use as a linearity check.
Quinine Sulfate Dihydrate in perchloric acid is an established reference material in fluorescence spectroscopy, designated SRM 936a by NIST. The provided data are based on its corrected fluorescence emission spectrum with an excitation wavelength of 347.5 nm, enabling reliable calibration of spectrofluorometers over the range 375 nm to 675 nm.
