Abstract
Various embodiments described herein relate to apparatuses and methods for detecting fluid particles and their characteristics. In various embodiments, a device for detecting fluid particles and their characteristics may comprise a lens free holographic microscope configured to collect fluid particles via inertial impaction. In various embodiments, the collection media may be replaceable within the apparatus. In various embodiments, the impactor nozzle may be selectively configured to avoid optical reflections and scattering from illumination light passing through the nozzle. Various embodiments are directed to a collection media assembly for receiving particles from a volume of fluid within a fluid composition sensor. A collection media assembly may comprise a collection media, an orifice, a seal engagement portion and a frame element configured to facilitate the serial use of a plurality of collection media assemblies within a fluid composition sensor.
