Embodiments of the present disclosure provide for systems, apparatuses, and methods for real-time fluid analysis. Embodiments include a removable and replaceable sampling system and an analytical system connected to the sampling system. A fluid may be routed through the sampling system and real-time data may be collected from the fluid via the sampling system. The sampling system may process and transmit the real-time data to the analytical system. The analytical system may include a command and control system that may receive and store the real-time data in a database and compare the real-time data to existing data for the fluid in the database to identify conditions in the fluid.

A particle detector that includes a housing defining a chamber, and an air stream injector, producing an airstream with entrained particles, in the chamber. A light source produces a light beam that intersects with and is wider than the air stream. A light detection assembly detects light generated by scattering of the light beam, by particles in the air stream. A digitizer produces a sequence of scattering digital values, each representing light detected per a first unit of time duration. Additionally, a summing assembly produces a sequence of summed scattering digital values, each equaling a sum of a sequential set of n of the digital values, and wherein successive summed digital values are offset by a the first unit of time duration and overlap by n1 of the first units of time duration with a nearest neighbor. Finally, a detection assembly processes the summed scattering digital values to detect particles.

Methods for using focused light scattering techniques for the optical sensing of biological particles suspended in a liquid medium are disclosed. The optical sensing enables one to characterize particles size and/or distribution in a given sample. This, in turn, allows one to identify the biological particles, determine their relative particle density, detect particle shedding, and identify particle aggregation. The methods are also useful in screening and optimizing drug candidates, evaluating the efficacy and dosage levels of such drugs, and in personalized medicine applications.

A system for acquiring a fluid sample from a flow pipe, comprising a sampling probe placed within the flow pipe, a curved separating pipe in fluid communication with the sampling probe, the separating pipe having formed therein an inwardly-opening lengthwise channel along the outside curve thereof, the separating pipe terminating in a sample area, and a lengthwise inwardly-opening sample passage in fluid communication between at least a portion of the sample area and a sample port, the sample passage being formed substantially opposite the channel, whereby inertial effects induced in the separating pipe cause relatively higher density inorganic and dead organic material to funnel into the channel and out a non-sample drain formed in the sample area substantially opposite the separating pipe while allowing live organisms to navigate the sample passage and out the sample port.
