Description

Molecular fluorescence spectroscopy is a sen­sitive and often selective technique. Unlike absorption spectrophotometry, it is not an absolute technique: instruments therefore require calibration before every series of measurements. This may be achieved using a stable reference material, which should absorb and emit at similar wavelengths to the samples of interest. Use of the general purpose fluorescent reference material set type 6BF enables the day to day stability of fluorescence instruments to be verified.

The 6BF reference materials are not standards with absolute values, but a set of six relatively stable fluorescent materials in a polymethyl-methacrylate matrix with which the stability of the instrument can be monitored. Four blocks exhibit broad band spectra which cover the normally used UV and visible region of the spectrum. Two blocks contain materials suitable for illustrating the selectivity of the technique as well as checking instrument resolution and wavelength calibration.

Description A set of 6 polymethylmethacrylate (PMMA) blocks in the dimensions of a standard cuvette. Each block holds a different fluroesence material in its matrix allowing for fluoresence calibration across a wide area of the spectrum
Primary Usage Calibration of fluorescence spectrophotometers and evaluation of methods used on the fluoresence spectrophotometer.
Useable Range 290nm to 573nm
Physical Configuration PMMA blocks with all sides polished in the dimensions of a standard 10mm pathlength cuvette.
Documentation Each set is supplied with a booklet which describes the use of the material and sample excitation and emmission curves
