A Research-Oriented Instrumental Analysis Experiment:Determination of Polychlorobiphenyls in Red Wine Samples
A comprehensive instrumental analysis experiment was designed based on persistent organochlorine pollutant detection.The quantitative and qualitative analysis of the organochlorine pollutants in red wine samples was carried out through infrared spectroscopy characterization,synchronous thermal analysis characterization,optimization of solid-phase microextraction conditions,and gas chromatography.The designed experiment allows students to participate in the entire instrumental analysis process and cultivates their ability to solve practical problems.
