Summary: | A system and method for thermal gradient gas chromatography wherein a front or injection end of a column is heated to a higher temperature than a back or detector end to thereby create a thermal gradient having a profile that is substantially monotonically non-increasing and has a positive second derivative, and then providing a heat source to raise the thermal gradient and cause it to remain stationary or to travel through the column while maintaining a desired profile. |
