& HOW TO ORDER

 

Samarium perchlorate is a particularly useful reference material for checking the wavelength scale
 over the commonly  used region from 200 nm to 500 nm.
It is accepted for this purpose by several Pharmacopoeias and Standardisation Bodies, including:

United States Pharmacopoeia
American Society for Testing and Materials
Therapeutic Goods Administration (Australia)
British Pharmacopoeia

Description and Discussion
Samarium (III) oxide in dilute perchloric acid, permanently sealed by heat fusion into a 10 mm far UV quartz cuvette.
Samarium perchlorate is a particularly suitable reference material for checking the wavelength scale of a spectrophotometer over the commonly used range of 200 to 500 nm, as it has peaks throughout this region. Many of the peaks are very narrow, providing very accurate location of the peak wavelengths.

 Samarium-Oxide-

 

samarium-oxide

Approximate peak wavelength values (in nm) are:
235, 279, 290, 305, 318, 332, 344, 362, 374, 391, 401, 415, 464, 479
