摘要： A chromatographic device includes a primary channel having a cross-sectional area and characteristic length such that analyte travel within the primary channel is substantially convective. A plurality of secondary channels each having a cross-sectional area and characteristic length such that analyte flow into and out of a secondary channel is substantially diffusive, each of the plurality of secondary channels having an entrance in fluidic communication with the primary channel wherein the entrance intersects the primary channel.

摘要： Techniques are described for accelerating thermal equilibrium in a chromatographic column. An apparatus comprises a chromatography column, and a plurality of temperature control units in thermal contact with the chromatography column. A method of performing liquid chromatography comprises setting an inlet of a chromatography column to a first temperature using a first temperature control unit in thermal contact with said inlet, setting an outlet of the chromatography column to a second temperature using a second temperature control unit in thermal contact with the outlet, wherein the first temperature is less than the second temperature; and injecting a sample into a liquid stream that flows through the chromatography column after the inlet is set at the first temperature and the outlet is at the second temperature.

摘要： Apparatus and methods for performing chromatography may include a chromatography column and a vacuum insulated jacket having an inner wall and an outer wall. A vacuum area may be formed between the inner wall and the outer wall. The inner wall of the vacuum insulated jacket may surround the chromatography column. A gap may be formed between an outer wall of the chromatography column and the inner wall of the vacuum insulated jacket. The vacuum insulated jacket may extend beyond one or more end frits of the column. The gap may be filled with one or more materials so as to form an insulating or thermal barrier.
