Estrone: Uv reflection spectrum in solid 1-tetradecanol

Abstract

Dissolved in 1-tetradecanol, estrone generates a characteristic uv reflection spectrum even in amounts of 0,005 μg (1.89 × 10 −11 mole) of estrone per mm 2 of reflecting area. A strong reflectance maximum at ν = 3.471μm −1 possesses the molar reflectance of 1,5 × 10 9 per mm 2, when smaller quantities than 1 × 10 −10 mole of estrone/mm 2 are measured. The application of measurements of uv reflection spectra for the determination of estrone is described in detail. The sensitivity, specificity, accuracy and precision of the method is high.
