Normalized corrected fluorescence emission spectrum BAM-F005b 560 - 770 nm

Remarks:
The CRM is available as a set of five solid dyes in bottles, in addition with the evaluation Software LinkCorrWin1.3. The CRM should be stored at 2 - 8°C in the dark. To measure the certified normalized corrected fluorescence emission spectra the Calibration Kit has to be dissolved in absolute Ethanol.

Intended Use:
The certified fluorescence emission standard BAM-FCalKit “Calibration Kit” contains BAM-F001b to BAM-F005b as a set and is a tool for the calibration and performance testing of fluorescence instruments. It enables the determination of the wavelength-dependent relative spectral Responsivity s(λ) of the emission channel/detection system of fluorescence instruments using the data of the CRMs of the Calibration Kit measured by the user under conditions used for routine fluorescence measurements and the BAM evaluation software LinkCorrWinV1.3.
