Abstract: A liquid sampling method in a flow monitoring system including a sampling section having a needle for performing sampling of a liquid, an analysis section that performs analysis of the liquid sampled by the sampling section, and a fluid supply section that supplies a sample fluid in a state of gas-liquid two-phase flow containing a gas phase and a liquid phase with the sample remaining in the state of gas-liquid two-phase flow. The liquid sampling method includes: a storage step of storing, in the storage container, a liquid phase contained in the sample fluid; a separation step of separating, from a liquid phase, a gas phase contained in the liquid phase stored in the storage container; and an injection step of suctioning, as a sample, the liquid phase stored in the storage container from a distal end of the needle after the separation step and injecting a predetermined amount of the sample into the analysis section through the injection port.

Abstract: Included are a sample supplier (2) 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 (4) provided downstream of the sample supplier (2), the gas-liquid separator (4) having a separation space (24) for separating gas and liquid in the sample fluid supplied from the sample supplier (2) from each other, a gas outlet (30) for releasing the gas in the sample fluid from the separation space (24), and a liquid outlet (28) for taking out the liquid in the sample fluid from the separation space (24), a liquid channel (32;42) fluidly connected to the liquid outlet (28) of the gas-liquid separator (4), a back pressure regulator (8) provided on the liquid channel (32; 34), an analysis channel (38; 40) constituting a liquid chromatograph for analyzing the liquid separated from the gas in the gas-liquid separator (4), and a sampling part (6) configured to take out the liquid flowing through the liquid channel (32; 42) and introduce the liquid into the analysis channel (40) between the liquid outlet (28) and the back pressure regulator (8) on the liquid channel (32; 42).
