Features
Gas compositions produced in refinery plants consist of hydrocarbons, permanent gases, H2S, etc. Analyzing these gases is essential to control the quality of chemical products and plant operation. Shimadzu’s RGA systems, available in numerous configurations, are designed to analyze various compositions in a variety of processes. In research and development for petrochemical and its catalysis field, target compounds often contain high-boiling point compounds and isomers. The Shimadzu CERGA makes it possible to precisely analyze those samples. In addition, calorific value calculation software is compliant with various calculation methods such as BTU and ISO-6976.

The ultrafast analysis system UFRGA series is now available.
