  • Publication number: 20210382017
    Abstract: A thermal modulator for a chromatographic system includes a cooler, a thermal valve, a thermal buffer, a heater, and a capillary. The thermal valve thermally-engages the cooler. The thermal buffer thermally-engages the thermal valve. The heater thermally-engages the thermal buffer. The capillary thermally-engages the heater and is configured to transport an analyte in a first direction.

  • Publication number: 20210356441
    Abstract: A method for modulating analytes in a gaseous stream passing through a capillary, wherein the analytes are retained in a trapping zone of the capillary, or allowed to pass therethrough, based on certain conditions. The method includes, during a first time period, heating the trapping zone of the capillary to a first temperature to desorb analytes therewithin and allow the analytes to pass therethrough, and during a second time period, cooling the capillary to a second temperature that is sufficient to trap and focus the analytes within the trapping zone. During the first time period, the method also includes retaining heat at the capillary during to minimize the load on a cooling device thermally connected thereto, and during the second time period, selectively allowing thermal transfer toward the cooling device.

  • Patent number: 11073502
    Abstract: This disclosure relates a device for a chromatographic system, comprising: a chamber defining an internal portion, a capillary disposed within the chamber, the capillary having an input, an output, and an elongate body extending between the input and the output, a cold finger having a first portion in thermal contact with a portion of the elongate body to define a capillary trapping zone, wherein the first portion of the cold finger extends to a second portion that is situated external to the chamber, a heater in thermal contact with the trapping zone of the capillary and configured to transfer heat to the trapping zone, a thermal buffer configured to buffer the heat from the heater into the cold finger and thereby retain the heat within the trapping zone of the capillary, a cooling device arranged external to the chamber and thermally connected to the second portion of the cold finger to define a primary conduction zone, wherein the cooling device is configured to generate a cooling temperature zone at the p
