DualCapt Non-Viable Particle Counter AND Microbial Air Sampler
What is the difference between physical and biological collection efficiency?
Physical efficiency is the ability of the microbial air sampler to collect various sizes of particles, and is the same regardless of particle composition (i.e. whether the particle is a microorganism, carries a microorganism, or is just an inanimate particle.)
Biological efficiency is the efficiency of the sampler in collecting microbe-carrying, still-viable particles.
