Abstract: Systems and methods are provided for determining a content of a hydrocarbon or other compound, such as a C3 to C7 hydrocarbon, in a condensed steam sample. Cooled steam condensate can be flowed through a sample chamber including an inner overflow tube. When the flow stops, water can be drained from the sample chamber, and then the sample chamber can be opened to allow fluid communication with a vapor chamber above the sample chamber. This can allow hydrocarbons in the condensed steam (and/or other gas) to be transferred from the sample chamber into the vapor chamber. The vapor chamber can then be isolated from the sample chamber. At least a portion of the content of the vapor chamber can then be passed to a detection volume, such as the characterization cell for a gas chromatography system.
