#<b>Black box</b>: The black box, or support circuitry, looks at the number of pulses in each bin and converts the information into particle data. </p>

<p>Light obscuration by particles works on the principle where the presence of particles blocks some of the light from the photodetector, typically through either <a href="page.php?w=absorbance">absorbance</a> or <a href="page.php?w=light_scattering">light scattering</a>. The photodetector records the obscuration of light and converts this to an electrical signal, this signal is then</p><p>
