PerkinElmer* Fluorescence Spectrophotometer Sample Blocks

For day-to-day checks on reproducibility and wavelength calibration, a set of six PMMA (polymethyl-methacrylate) blocks can be used. These have emission characteristics in the following wavelength ranges:

Wavelength Range (nm)
1 300 - 400 (anthracene/naphthalene)
2 420 - 600 (ovalene)
3 300 - 400 (p-terphenyl)
4 400 - 600 (tetraphenylbutadiene)
5 600 - 640 (europium)
6 540 - 640 (rhodamine B)

For checking instrument sensitivity, a 10 mm sealed cell contains high-purity water, which acts as a constant sample to reproducibly measure signal-to-noise using the Raman band.
