Introduction

Column chromatography is based on the principle that components in a sample mixture exhibit different distribution rates between the stationary and mobile phases. Separation occurs after multiple distribution cycles. We have supplied high-quality equipment to numerous customers in the pharmaceutical, nutraceutical, and food industries-including leading drug manufacturers, functional food producers, and natural extract processors.
We have accumulated extensive practical experience in separation process optimization, customized chromatography column design, and post-installation technical support. Our expertise covers both laboratory-scale R&D and industrial-scale mass production, ensuring compatibility with diverse application requirements.
Structure
This normal-pressure chromatography column system consists of a blending and feeding unit (for uniform mixing and accurate metering of raw materials), an elevated tank (to provide stable liquid pressure for continuous operation), a chromatography column assembly (modular design for flexible configuration), a horizontal tank (for temporary collection and storage of separated components), and a complete set of instruments (for real-time monitoring of flow rate, pressure, and temperature). All components feature standardized connections, facilitating easy assembly, maintenance, and future capacity expansion.

Features
1) Specialized customization service: different product, different capacity with different program;
2) Automatic stationary phase loading and unloading design, easy operation;
3) Good inner surface quality of column;
4) You can choose between automatic control and manual control.

Models
We manufacture custom chromatography columns in various sizes and specifications according to customers' specific requirements. Options include column diameter (from 50 mm for laboratory use to 1500 mm for industrial production), column height, material selection (stainless steel, glass-lined steel, or special alloys), and internal configuration (packed bed or expanded bed design). Our engineering team provides professional technical consultation to help select the optimal model for specific separation tasks and production scales.
Application
This technology is primarily used for the separation and purification of components from natural plant extracts. Examples include efficient separation of THC and CBD in hemp extracts, and concentration of bioactive compounds such as flavonoids, alkaloids, and polysaccharides from traditional Chinese medicines and herbal materials.
It is also widely applied in the separation of food additives, purification of pharmaceutical intermediates, and refinement of natural pigments. The technology provides reliable support for the development of high-value products in the pharmaceutical, nutraceutical, and food industries.
