Abstract

Included are a sample supplier () configured to generate a sample fluid containing gas and liquid by causing two or more kinds of fluids to react with each other and to supply the sample fluid, a gas-liquid separator () provided downstream of the sample supplier (), the gas-liquid separator () having a separation space () for separating gas and liquid in the sample fluid supplied from the sample supplier () from each other, a gas outlet () for releasing the gas in the sample fluid from the separation space (), and a liquid outlet () for taking out the liquid in the sample fluid from the separation space (), a liquid channel () fluidly connected to the liquid outlet () of the gas-liquid separator (), a back pressure regulator () provided on the liquid channel (), an analysis channel () constituting a liquid chromatograph for analyzing the liquid separated from the gas in the gas-liquid separator (), and a sampling part () configured to take out the liquid flowing through the liquid channel () and introduce the liquid into the analysis channel () between the liquid outlet () and the back pressure regulator () on the liquid channel ().
