A temperature programmed low thermal mass fast liquid chromatography system capable of high throughput and low power consumption includes a straight or curved short reloadable low-mass tubular heater with a capillary column extending inside. If the capillary column is long enough, it is coiled to form a coiled capillary LC column (the length of which does not exceed 0.2 m-1.0 m) packed in a singular module package with a heating wire and a temperature sensing wire extending along and in proximity to the LC capillary column. A tubular heater, e.g. a steel tubing, incorporates the LC capillary column, along with the heating wire and the temperatures sensor and is coiled to form a miniature power saving LC module which may be attached outside a chromatography oven. Capillary lengths extend inside the oven between the inlet and outlet of the LC column module and mobile phase source and detector, respectively. An electronic temperature control block is positioned outside the oven cavity and controls the heating of the capillary LC column, as well as other heated zones in the system.
