Systems and methods are provided for determining a content of a hydrocarbon or other compound, such as a C3to C7hydrocarbon, in a condensed steam sample. Cooled steam condensate can be flowed through a sample chamber 110 including an inner overflow tube 120. When the flow stops, water can be drained from the sample chamber 110, and then the sample chamber can be opened to allow fluid communication with a vapor chamber 140 above the sample chamber 110. This can allow hydrocarbons in the condensed steam (and/or other gas) to be transferred from the sample chamber 110 into the vapor chamber 140. The vapor chamber 140 can then be isolated from the sample chamber 110. At least a portion of the content of the vapor chamber 140 can then be passed to a detection volume 160, such as the characterization cell for a gas chromatography system.
