What is Multi Stages High Performance Chromatography Columns
Separation Process of High-purity Target Components from Natural Products
Eluent has low water content, and Sample and Modifier (which can be pure water) have high water content, so the upstream water content of the feed port is low and the elution ability is strong; while the downstream water content is high and the elution ability is weak.
During the operation, the main component (gray in the figure) flows out, and when the rear miscellaneous (black in the figure) is about to flow out of the column 2, the system switches and the two columns exchange positions.
After switching, the Eluent with low water content eluted column 2, and the post-column was quickly eluted into column 1 downstream of the feed port.
At the same time, the water content in the column 1 is high, and the separated components move slowly, so that the main component can flow out of the column 1, and when the post-mix starts to flow out of the column 1, the system switches.
During the operation, the post-impurities does not flow out of the system, that is, it is captured in the system and is enriched.

Practical User's Requirements
The daily processing of the mosaic leaves is not less than 1.5T;
It is required to meet the daily production capacity of CBD pure product of not less than 10kg;
The final CBD crystal is required to have a purity of ≥99.0%, wherein the THC does not exceed 0.1%;
The final full spectrum oil is required: CBD content ≥ 55.0%, THC content not more than 0.1%, total polyphenol content ≥ 80.0%;
It is required that the transfer rate of the CBD from the extraction of the leaves to the final product is ≥60% or higher, the higher the better;
