Research on Multidimensional Liquid Chromatography Sample Pretreatment System

Using multidimensional liquid chromatography technology, a liquid chromatography sample pretreatment system which was controlled by a microcontroller was designed. Real sample pretreatment experiments have been done. The experimental results showed that the complex samples can be separated effectively with this system according to 3 polarities. The operation of this system is simple, fast and high automatic, which meet the requirements of pretreatment of liquid chromatography complex samples.
