Rare Earth (Cerium) liquid filter (200- 260 nm)

The rare earth (Cerium) liquid filter consists of a solution of rare earth metals dissolved in perchloric acid. This filter is ideally suited for checking the wavelength accuracy of spectrophotometers in the low UV range. It has a spectrum with five characteristic peaks in the range from 200 nm to 260 nm.

This filter is recommended in the Ph. Eur. and in the USP 857 for checking the wavelength accuracy in the range of 200 - 260 nm.

Ph. Eur. = European Pharmacopoeia
USP = United States Pharmacopeia
