混药浓度检测技术研究现状

Research Status of Mixed Drug Concentration Detection Technology

混药是施药的基本操作环节,混合药液品质直接决定施药效果,发展浓度检测技术可以监控混合药液的品质。目前混药浓度的检测方法主要分为两大类:第一类,先采集喷雾样品溶液再利用仪器测量浓度,简称取样检测浓度法;第二类,在混合后喷雾前即在线混药时直接测量浓度,简称在线检测浓度法。重点阐述了这两大类国内外主流的混药浓度检测技术,并对其进行总结分析。

Drug mixing is the basic operation link of drug application.The quality of its mixed solution directly determines the application effect.The development of concentration detection technology can monitor the quality of mixed solution.At present,the detection methods of mixed drug concentration can be divided into two main categories:first,collect the spray sample solution first,then use the instrument to measure the concentration.The second type is to measure the concentration directly before mixing,namely on-line concentration.This paper focuses on the two mainstream mixed drug concentration detection technologies at home and abroad,and summarizes and analyzes them.
