Abstract
In some embodiments, an apparatus and a system, as well as a method and an article, may operate to terminate sampling of fluid into one of a set of fluid sampling chambers sharing a common inflow sampling line by operating a set of closure mechanisms. Further activity may include initiating sampling of the fluid into another one of the set of fluid sampling 5 chambers, wherein the fluid sampling chambers are configured to sample the fluid in the sampling line in a selected sequence, such that filling a prior fluid sampling chamber as part of the sequence enables sampling in the next fluid sampling chamber as part of the sequence, and wherein the closure mechanisms comprise individual check valves 10 and a common diversion valve or individual diversion valves. Additional apparatus, systems, and methods are disclosed.
