ABSTRACT
The quality of an alpha-tocopherol standard can be checked easily by measuring the UV absorbance at minimum (255 nm, Amin) and maximum (292 nm, Amax) wavelengths in n-hexane. If the quotient Amin/Amax exceeds 0.18, the standard contains less than 90% alpha-tocopherol and the determination at 292 nm will yield inaccurate results.
