Chapter 3: Theory of Operation
A clean, contamination-free work environment is critical to maximize yields as certain
particles are likely to cause defects, irregularities, inaccuracies and even failures. Analyzing
particle contaminants is an important step in having control over operating environments
and reducing particle deposition in critical components.
Isolating, characterizing and understanding the types of particles found in products or
processes can usually yield a likely source for the particles. Once the source is known then
elimination of the particulate contamination becomes substantially easier.
II. PARTICLE DETECTION
PARTICLE COUNTING PRINCIPLE
A particle counter is an instrument that detects and counts particles. A particle counter
works on the principle of either light scattering, light blocking, or condensation for detecting
and measuring particle size or size distribution.
When a particle is illuminated by a light beam, light is reemitted (if light scattering is used) or
absorbed (obstruction). The scattered or absorbed light (depending on method used) is
detected by a photo detector, measured, and the particle is counted and tabulated into
standardized counting bins. If direct imaging is used, light illuminates particles from the back

TCH Pro v1.2.1

Operation Manual TCH Pro 202 & 203
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.

III. CALIBRATION
PROCESS
Flow calibration is performed with a low back pressure - displaced volume - calibration-
grade flow meter. Particle size calibration is performed in four stages with NIST-traceable
mono-size polystyrene spheres.
•Stage 1, wet aerosol. Particles smaller than 2µm are diluted in UDI water and atomized.
The mist containing particles is dried, static charges are neutralized and the dry aerosol is
sampled by the Particle Analyzer.
•Stage 2, dry particles. Particles between 2µm and 10µm are stored dry and fed directly
into the Particle Analyzer.
•Stage 3, peak location determination and loading of calibration values.
•Stage 4, reference comparison. Calibrated device results are compared against a
reference unit to determine counting efficiency.
The APA Pro 202 and 203 are calibrated with 7 different traceable particle sizes:
•Liquid solution (atomized and dried): 0.2µm, 0.3µm, 0.5µm, 1.0µm and 2.0µm
•Dry: 3.0µm and 10.0µm
