Natural Gas Analysis

Add Bookmark

Recently, natural gas has been recognized as a clean resournce for energy, in addition to being a raw material for chemical products. Recently a cutting-edge drilling technology has increased the use of shale gas. As the production area diversifies, the need for gas composition analysis has increased. Shimadzu addresses analytical requests with a wide system GC lineup. For analysis of liquified gas, such as LPG, a dedicated injector with a vaporizer is available. Both manual injection and online injection are available. The operation software can automatically calculate needed values, such as indexes, calorific values, etc.

The ultrafast natural gas analyzer UFRGA is here.
