Claims

[Scope of utility model registration request]

A gas flow path having a sample flow path through which a sample liquid flows and a gas flow path through which a carrier gas flows, and through which a certain amount of the sample liquid flows through the carrier gas by a piston rod provided across the two flow paths. The fluid sample collection device is characterized in that means for blocking the sample flow path is provided in the vicinity of the piston rod downstream of a position where the piston rod crosses the flow path. Liquid sample collection device.
