Abstract
Various embodiments are directed to a collection media assembly for receiving one or more particles from a volume of fluid within a fluid composition sensor. In various embodiments, the collection media assembly comprises a housing, a transparent substrate, a collection media disposed upon the transparent substrate and configured to receive one or more particles from a volume of fluid received through a fluid inlet; and at least one alignment feature. The housing defines an open lower end configured for interaction with an imaging device, such that the one or more particles received by the collection media are visible through the transparent substrate from the open lower end. Each of the at least one alignment features is configured to engage a corresponding element disposed within the fluid composition sensor so as to constrain relative movement between the collection media assembly and the corresponding element in at least a first direction.
