Abstract
A hydrocarbon vapor analyzer for direct measurement of the percentage by volume of hydrocarbon vapor is a portable device utilizing two substantially identical vertically disposed graduated cylinders or burettes in which are mounted slidable and adjustable pistons for varying volumetric conditions and measuring changes in volumetric conditions of vapor mixtures of air and hydrocarbon being analyzed therein. One of the graduated cylinders defines a chamber for receiving the sample vapor mixture to be analyzed and the other provides a means for measuring the sample after it is transferred to the second burette through a device for absorbing the hydrocarbon vapor from the vapor mixture to be analyzed. The sample receiving burette has an operatively associated manifolding system which includes, an inlet valve for controlling the flow of the sample mixture of vapor to be analyzed to the sample receiving graduated cylinder, and a transfer valve for passing the vapor sample to be analyzed through the absorber for removing the hydrocarbon vapors to the graduated cylinder for measuring the net volume of hydrocarbon vapor absorbed from the sample mixture of vapor being analyzed. The respecti…
