As to carbon dioxide as a food additive, oil (high-boiling point lubricating oil and others) is the object of measurement as well as inorganic gas components such as H2, O2, N2, sulfur compounds and hydrocarbon components. Out of them, oil had been conventionally measured according to the IR method after absorption in carbon tetrachloride. However, carbon tetrachloride could not be used as a result of enforcement of control of CFC. It was thus the problem with the IR method that long time is inevitable including pretreatment. This system performs full automatic operations of all processes, ranging from sample enrichment to FID measurement in adoption of the gas chromatograph method.
This system is an item with utility model acquired (expiration of validity) featured in unique method of measurement not seen with products of other companies. As a result of establishment of full automatic operations, drastic labor saving and cost reduction have been attained as well as considerable improvement productivity in quality management activities.
