|Notes||Benzene is a popular industrial solvent and a precursor to many other aromatic chemicals. Determination of thiophene in benzene by ASTM D7011 is achieved using a sulfur selective detector. Most sulfur selective detectors will show signs of quenching at the point when the hydrocarbon solvent elutes. Therefore, for successful analysis, it is vital to separate thiophene from benzene. Rtx-Wax columns provide the required inertness and proper selectivity needed to separate those two compounds.|
