Abstract
A method for determining volative components in a continuous flow condensed phase sample stream. A method is disclosed wherein a controlled flow of a sample stream of oil is cascaded down a standpipe of a predetermined length and a countercurrent flow of an inert dry gas is created to absorb volatile substances, such as water, in a concentration proportional to the concentration in the oil. The cascade of oil down the standpipe creates an efficient mechanism for the transfer of volatiles from the oil to a gas phase with the inert gas. The inert gas exposed to and containing the volatiles is applied to a detection system for the measurement of the concentration of the volatiles.
