幸运8平台彩票Determination of Benzene in Gasoline by ASTM D6277 with Spectrum Two

Introduction

IR spectroscopy is an ideal method for quantifying benzene at the concentration levels required, and there are several standard methods for this measurement, all of which utilize the distinctive C–H out-of-plane deformation band at around 673 cm-1. While this band is characteristic of benzene, toluene and xylenes have some weak absorption at this frequency that can interfere with the results if high concentrations are present.
