CO2 extraction (SFE) uses carbon dioxide to obtain a plant extract without the use of hazardous chemicals and solvents that could contaminate the final product. This results in high purity extracts. CO2 extraction is considered a green chemistry due its clean and safe processing features that has no negative impact on the environment.
DAC stands for dynamic axial compression. DAC technology makes chromatography possible on large ID columns (&20cm) by maintaining high density of the column packing. It is essential technology for providing separation efficiency, repeatability, and overall performance throughout the life of the column at process scale. High column efficiency is necessary to separate and isolate compounds from the complex mixtures characteristic of natural products.
