Abstract: A gas-liquid separator system that can effectively and efficiently separate liquid from a streaming mixture having a liquid portion and a gas portion. The gas-liquid separator may be used in supercritical fluid chromatography application where an analyte is separated from a carrier gas, such as carbon dioxide. A streaming mixture is dispensed into a separation chamber formed by a spindle shaft configured inside of a shroud cavity. The shroud cavity has a plurality of concave channels along the inner surface and extend down to an outlet end. The concave channels create pressure variations that promote the liquid portion to condense onto the inner surface of the shroud and flow down to the exhaust port. A spherical collection portion is configured on the outlet of the shroud and the condensed liquid flows thereover and down along a cone portion and off the cone tip.

Abstract: A device is provided herein which comprises first (203) and second (207) substrates, and a composition (205) disposed between the first and second substrates. The composition comprises a continuous phase and a disperse phase, wherein said continuous phase comprises a partially crosslinked polyorganosiloxane having a polymer backbone, and wherein the number of monomeric units in the polymer backbone is within the range of about 2,000 to about 15,000.
