Abstract: Automated systems and methods for obtaining of the concentration of impurities in a liquid ethylene oxide product stream are shown and described. The systems and methods employ remote injection and flash vaporization of small volumes of liquid ethylene oxide into a carrier gas to minimize polymerization of the ethylene oxide and accumulation of polymerized ethylene oxide. Ethylene oxide peaks are diverted from the gas chromatograph effluent detector to stabilize baseline signal errors and avoid errors in the calculation of an impurity with an adjacent retention time peak. The systems and methods may be used for feedback, feedforward, dynamic matrix, and/or model-based predictive control of ethylene oxide purity. The systems and methods reduce lag times and errors associated with relying on laboratory analyses to make process adjustments.
