Transverse thermal modulation |
摘要 |
A method of thermally modulating a tubular member carrying a sample substance therethrough is provided. The method includes the steps of (a) directing at least one gas stream toward a tubular member in a direction substantially transverse to the tubular member, wherein the temperature of the gas stream differs from the temperature of the tubular member; and (b) varying the gas flow rate of the at least one gas stream as a function of time to thermally modulate the tubular member. An apparatus is also provided for thermal modulation and includes: a tubular member for carrying a sample substance therethrough in a fluid medium; a gas stream source for directing a gas stream toward the tubular member in a direction substantially transverse to the tubular member; a gas stream supplied from the source with a temperature that differs from the temperature of the tubular member; and a gas stream of varying gas flow rate supplied from the gas stream source as a function of time to thermally modulate the tubular member. |
