Estimating the term…
A miniature gas chromatograph with thermostatically-controlled heating of its component parts which contact and conduct the sample to the analytical column. The microvalve assembly of the gas chromatograph is heated by passing a thermostatically-controlled electrical current through a metallic conductor formed on a surface of the microvalve assembly. The tubing which conducts sample from the gas chromatograph sample inlet to the microvalve assembly is heated by passing a thermostatically-controlled electrical current directly through the tubing or through a metal layer formed around the tubing. The sample inlet fitting is heated by a wire heater element wrapped around it. Each heater has an associated temperature sensor for controlling the amount of heating to maintain a predetermined temperature.
A microvalve assembly comprising:
A microvalve assembly comprising:
A method of controllably heating a microvalve assembly which includes as elements a valve body, a tube connected at one end to the valve body, and a fitting for connection of the tube to a fluid source or sink and located at the other end of the tube, comprising the steps of:
