Described is a dual mode sample manager for a liquid chromatography system. The dual mode sample manager includes a sample needle, a sample loop, a metering pump, a needle seat and first and second valves. Each valve is configurable in two valve states to enable two modes of operation. In one mode, sample acquired and stored in the sample needle is injected into a chromatography system flow and, in the other mode, sample acquired through the sample needle and stored in the sample loop is injected into the chromatography system flow. The automated switching of the sample manager between the two modes of operation avoids the need for maintaining two separate liquid chromatography systems or manual reconfiguration of a chromatography system for users desiring the capability of both modes of operation.

The present invention provides a dynamic interface system between an extraction device and a chromatographic purification device for separating and purifying substance(s) from a mixture or matrix. One embodiment is the Supercritical Fluid Interface (“SFI”) between Supercritical Fluid Extraction (“SFE”), and Supercritical Fluid Chromatography (“SFC”). The SFI is capable of interfacing; gas, subcritical and supercritical fluid extraction methods and pair with gas, subcritical and supercritical fluid chromatography technologies that operate within the pressure and temperature parameters of the SFI. The SFI can operate up to 200 degrees celsius and 5000 psi. This interface technology allows for an inline oil extraction and chromatographic separation, the SFI can pair extraction and chromatography with the same solvent in different mobile phases, whereas the extraction can be performed using CO.sub.2 as a solvent in sub-critical phase and the SFI can receive the subcritical solution and then increase pressure and/or temperature to achieve supercritical state as required for injection into supercritical fluid chromatography technologies. The SFI coupling between SFE and SFC can to extract and refine cannabinoids from the cannabis industrious, hemp, plant and can also be applied to improve efficiency in an industry that extracts and refines oils, through chromatography, from organic materials using a gas, or sub/supercritical fluid as a solvent and mobile phase.
