A flow of a chemical is mixed with a flow of a primary fluid to form a combined fluid, and during mixing a velocity of the combined fluid is maintained at a threshold value so that a resulting mixture of the chemical and primary fluid has a designated homogeneity. The primary fluid is directed to an end of a passage with a venturi like contour that is inside of a mixer, and the chemical is directed to a side passage that extends laterally in the mixer that intersects the passage. A spring loaded valve in the passage maintains the combined flow velocity at the threshold value.

Methods for the detection of components from biological samples are provided. In certain aspects, the methods may be used to detect and/or quantify specific components in a biological sample, such as tumor cells (e.g., circulating tumor cells). Systems and devices for practicing the subject methods are also provided.

Disclosed is a system for mixing gases and liquids that includes a reactor vessel and an injection assembly. The reactor vessel including a liquid inlet which receives a predetermined amount of liquid and at least one gas inlet which receives a precise amount of a gas. The reactor vessel also includes means for creating cavitation or turbulence for mixing the gas and liquid to a desired gas concentration.
