Abstract: 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.

Abstract: The present disclosure relates to methods and workflows for processing and analyzing clinical samples (e.g., nasal swabs, throat swabs, plasma samples, urine, etc.) In general, the methods and workflows involve the detection of an infectious state and are improved over contemporary methods due to increased throughput with improved resolution of positive results.
