For optimal results in HPLC analysis, it is recommended to measure absorbance at a wavelength that matches the absorption maximum of the compound(s) being analyzed. The UV spectrum shown can assist in selecting an appropriate wavelength for your analysis. Please note that certain mobile phases and buffers may block wavelengths below 230 nm, rendering absorbance measurement at these wavelengths ineffective. If detection below 230 nm is required, it is recommended to use acetonitrile and water as low UV-transparent mobile phases, with phosphoric acid and its salts, sulfuric acid, and TFA as buffers.
For some compounds, the UV-Vis Spectrum is affected by the pH of the mobile phase. The spectra presented here are measured with an acidic mobile phase that has a pH of 3 or lower.

HPLC Method for D-alpha-Tocopheryl acetate on Newcrom R1 by SIELC Technologies

High Performance Liquid Chromatography (HPLC) Method for Analysis of D-alpha-Tocopheryl acetate 

D-alpha-Tocopheryl acetate is a form of Vitamin E with a molucular formula of C₃₁H₅₂O₃. It is also known as alpha-tocopheryl acetate. It is often used in cosmetics, food, and dietary supplements due to its antioxidant properties.

D-alpha-Tocopheryl acetate can be retained and analyzed using the Newcrom R1 stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN) with a phosphoric acid buffer. Detection is performed using UV.
