Abstract: A high throughput high performance chromatography system operating at a high mixing pressure including a plurality of pressurized solvent reservoirs, e.g. pumps, each maintaining an associated solvent at a substantially constant pressure. A plurality of flow control valves are connected downstream or upstream of the reservoirs for controlling the flow rate of the solvent into the respective columns. The number of reservoirs equals the number of solvents. Accordingly, the system reduces the number of pumps required thereby saving money and space. Furthermore, the system increases sample throughput, accelerates method development and minimizes organic waste.

Abstract: A mixture of two or more fluid molecular species is resolved into its compartment parts by a selective separation process whereby the mixture is contacted with a solid particulate monomeric cyclodextrin. On contact, at least one of the molecular species is selectively sorbed onto the cyclodextrin, and thereafter the species is desorbed from the cyclodextrin. In a preferred aspect, the species to be separated are organic compounds.
