PC-300-1-1000 series medium pressure liquid chromatography system, 2-10Mp (Application level: laboratory preparation, pilot scale, small-scale industrial grade)
System Characteristics
Modular design
Convenient for users to choose and match the required equipment, and with a small footprint.Gradient configuration; It can run precise binary gradients and can also be configured equally;All valve and other pipeline joints are located on the right side, and a reasonable pipeline layout greatly reduces dead volume in the pipeline. Connecting the instrument backend to a fixed column can form a whole, making it convenient for users to choose and match.
infusion system
Dual plunger parallel mode, floating plunger design, online real-time cleaning function, maintenance free.
detection system
The online 190nm-700nm UV detector (or other online detectors) uses imported deuterium and tungsten lamp light sources, ensuring reliable quality.
Valve collection
Powerful automatic collection capability, supporting full collection and peak collection (threshold, slope).
software
The automatic buffer preparation function facilitates quick exploration of purification processes, and the corresponding parameters are programmed according to on-site process requirements. Real time monitoring and control of flow paths; The same screen displays UV, gradient spectral lines, and collection tube numbers. Automatic software control improves the purity and repeatability of collection, enabling the system to obtain more separation information of samples and impurities in a timely manner, making the tedious chromatographic purification process easy and convenient.
