Introduction to Particle Counting

Introduction to Particle Counting Particle counting may be performed using two different techniques, each with its own limitations and interferences, but one aspect they share in common is that they are both only a quantitative count. Neither method identifies the composition or source of the particles, they only provide a level of particles per ml…
