within a cell while a high definition, high magnification camera records passing particles.
Recorded video is then analyzed by computer software to measure particle attributes.
Notes:
•
The
light blocking optical particle counter method
is typically useful for detecting
and sizing particles greater than 1 micrometer in size. This type of technique allows high
resolution and reliable measurement.
•
The
light scattering method
is capable of detecting smaller sizing particles. Typical
detection sensitivity of the light scattering method ranges between 0.1µm to 25µm.
Scattered light is significantly smaller for small particle sizes. A 0.2µm particle emits
1*10
-10
of the intensity emitted by a 10µm particle.
•
The
condensation method
is used to detect particles over 5nm, but it cannot
differentiate among different particle sizes.
