Patent ID: 7994453

Claim:
A method according for providing a gas sampling tube, comprising: providing a foil with an electrically-conducting surface; clamping, with a first clamping mechanism, the foil into an annular shape at a first end of the annular shape; clamping, with a second clamping mechanism, the foil into the annular shape at an opposite second end of the annular shape; supplying a flow of electricity sequentially through the first clamping mechanism, the foil, and the second clamping mechanism in order to heat the foil; separating the first clamping mechanism and the second clamping mechanism to provide structural rigidity to the annular shape; and controlling the flow of electricity to heat the foil at a rate of at least 25 degrees Celsius per second, wherein a temperature sequence including at least one temperature of the foil is controlled according to performance of at least one of: condensing chemical vapor, transmitting the chemical vapor, desorbing condensed chemical vapor, and decomposing condensed chemical vapor, and wherein the foil is one of: a metal, a polymer with an electrically conductive coating, a flexible ceramic with an electrically conductive coating, a laminate of an electrically conductive material and an electrically insulating material.
