Abstract: The present invention relates to a method and device for conducting the analysis of hydrocarbons in aqueous solutions, accurately matching the EPA Test Method 1664 HEM, without the need for a solvent extraction step. The solvent extraction step is eliminated by: 1) delivering the aqueous solution directly to a standard cuvette in a controlled and convenient manner, and 2) correlating the analyzer's output reading to a predetermined calibration curve. The predetermined calibration curve is generated by having a duplicate sample of aqueous solution tested by Method 1664 and the present device and the two values correlated. The sample delivery system is comprised of a standard 1-liter sample bottle, a flow control section, and an analyzer adapting section. The sample bottle contains the aqueous solution to be analyzed.
