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.
