A sampling assembly and a method of operation of a sampling assembly are described. An assembly according to an embodiment includes an inlet, an outlet, a liquid-flowing section disposed between the inlet and the outlet, a vapor-flowing section disposed between the inlet and the outlet, and a probe port on the liquid-flowing section. The vapor-flowing section is distinct from and above the liquid-flowing section. A method according to an embodiment includes receiving a liquid chemical interspersed with a gas at an inlet of a sampling assembly and segregating the liquid chemical from the gas. The liquid chemical flows in a liquid-flowing section of the sampling assembly, and the gas flows in a vapor-flowing section of the sampling assembly. The method further includes monitoring a property of the liquid chemical in the liquid-flowing section and releasing the liquid chemical and the gas through an outlet of the sampling assembly.

A sheet manufacturing apparatus includes a pipe that supplies a material containing fibers, a collision section with which the material moving from the pipe collides, and an accumulation section that is disposed downstream of the collision section and accumulates the material to form a web.
