继开发用于分析含有微量洗涤剂残留物的废水和水的溶剂萃取系统之后，设计了一种从怀疑含有关税折扣瓦斯油的烃油样品中萃取醌茜的系统。这是通过结合前面描述的两个系统的原理来实现的，并且已经以原型形式构建了一个单元。通过将溶剂萃取系统与记录分光光度计的流通池连接，实现了油中存在的醌茜的鉴定和测定。醌茜通过特征光谱图进行识别，并通过 521 nm 峰的峰高确定。
Following the development of solvent-extraction systems for the analysis of effluents and water containing traces of detergent residues, a system for the extraction of quinizarin from samples of hydrocarbon oils suspected of containing duty rebated gas oil has been designed. This has been achieved by combining the principles of both systems described previously, and a unit has been constructed in prototype form. Identification and determination of the quinizarin present in the oil has been achieved by linking the solvent-extraction system with a flow-through cell of a recording spectrophotometer. Quinizarin is identified by the characteristic spectral pattern and determined by the peak height of the 521 nm peak.
