In situ fluid sampling device and method of using the same

A device for detecting fluid particle characteristics comprising:

• a fluid composition sensor configured to receive a fluid sample comprising a plurality of particles, the fluid composition sensor comprising:
• an internal sensor portion configured to receive a collection media assembly comprising a collection media, the collection media comprising:
• an absorbent media and a biologically nutritive substance dispersed on the absorbent media, wherein a volume of the biologically nutritive substance dispersed on the absorbent media is based at least in part on one or more filter characteristics of the absorbent media, and wherein the collection media is configured to receive at least a portion of the plurality of particles from within the fluid sample;
• and
• an imaging device configured to generate first particle data using a particle imaging operation, the first particle data being associated with an initial particle configuration defined by the plurality of particles at a first instance;
• a controller configured to determine a biological particle characteristic associated with the fluid sample based at least in part on a comparison of the first particle data and second particle data, the second particle data being associated with an incubated particle configuration defined by the plurality of particles at a second instance, wherein the second instance is subsequent an incubation operation wherein at least a portion of the plurality of particles are exposed to an incubation environment.
