制备色谱已经成为色谱科学的一个独立分支,因此单组分色谱纯试剂早已作为商品出售,并已在色谱科学研究工作和定性、定量分析中得到了广泛的应用。随着色谱科学和色谱分析工作的发展,具有一定组成并稳定不变的色谱双组分标准试剂,已成为色谱学科中重要的标准化试剂。作为双组分色谱标准试剂,需要具有组成准确和稳定不变的特点。显然,如果用单一的色谱纯试剂按所需要的成分进行配制,将因操作者的不同而引入误差,更重要的是这种双组
Preparative chromatography has become an independent branch of chromatography science, so the one-component chromatographic pure reagent has long been sold as a commodity and has been widely used in chromatographic scientific research and qualitative and quantitative analysis. With the development of chromatographic science and chromatographic analysis, the chromatographic two-component standard reagent with a certain composition and stability has become an important standardized reagent in chromatography. As a two-component chromatographic standard reagents, need to have the composition of accurate and stable characteristics. Obviously, if a single chromatographic reagent is used to prepare the desired components, the error will be introduced depending on the operator. More importantly, the two-group
