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.
Claims17
A thermal modulator for a chromatographic system, the thermal modulator comprising:
- a first cooler;
- a thermal valve thermally-engaging the first cooler, the thermal valve including an anisotropic material operable to transfer heat at a first rate in the first direction and at a second rate in a second direction transverse to the first direction;
- a thermal buffer thermally-engaging the thermal valve;
- a heater thermally-engaging the thermal buffer;
- and
- a capillary thermally-engaging the heater and configured to transport an analyte in a first direction.

A thermal modulator for a chromatographic system, the thermal modulator comprising:
- a first thermoelectric cooler;
- a cold reservoir thermally-engaging the first thermoelectric cooler;
- a thermal buffer thermally-engaging the cold reservoir;
- a heater thermally-engaging the thermal buffer;
- a capillary thermally-engaging the heater and configured to transport an analyte in a first direction;
- and
- an anisotropic material disposed between, and thermally-engaging, the thermal buffer and the cold reservoir.
