What does HIAC particle counter mean?
High Accuracy
HIAC stands for “High Accuracy” liquid particle counter. Liquid particle counters are commonly used to perform sizing and counting of particulate while in a solution.
Which is called as obscuration technique?
The laser light source is used to illuminate the individual particles resulting in a shadow or a blockage of light. This shadow or blockage is often called “obscuration”, which is how this particular analytical technique was granted its name.

How does an air particle sensor work?
Particle sensors are small air monitors that measure airborne particles such as smoke and dust. A beam of light inside the sensor is passed through a sample of air, and particles in the sample scatter the light beam. The scattered light is measured and used to calculate the concentration of particles in the air sample.

How do liquid particle counters work?
An aerosol particle counter works on the principal of either light scattering or light blocking. An aerosol stream is drawn through a chamber with a light source (either Laser Based Light or White Light). When a particle is illuminated by this light beam, it is redirected or absorbed.
What is Micro flow imaging?
Micro-flow imaging (MFI) is a well-established and frequently-used technique for sizing, quantifying, visualizing and, in certain cases, identifying (sub-) visible particles. MFI has become an established technique for subvisible particle analysis, though no monograph/specifications in the pharmacopoeias exist so far.
How does the HIAC 9703 liquid particle counter work?
PharmSpec Software works with the HIAC 9703+ liquid particle counter system to test parenteral products for sub-visible particle content using light obscuration in accordance with USP<787>, <788> and EP 2.9.19. Flexible calibration at multiple flow rates improves ease of sampling for varying sample viscosities and volumes.
Who is the founder of HIAC particle counting?
In the early 1960’s Leon D. Carver and his team at HIAC (High Accuracy Products) invented light obscuration and the term particle counting was born. HIAC was the first company in the world to use a laser light source for light obscuration sensors.
Which is the best method for measuring subvisible particles?
Light Obscuration is currently the common compendial method used for measuring subvisible particles in therapeutics. Applicable size range: 2 – 102μm Modifications to USP<788> enable more accurate testing of subvisible particles but challenges still exist Reduced sample volume required for testing (single units ≥
Which is the best liquid particle counting software?
HIAC is the benchmark name in liquid particle counting for laboratories and industrial applications. HIAC 9703+ Pharmaceutical Particle Counter PharmSpec software is 21 CFR Part 11 ALCOA compliant Secure database is either sited on the local pc operating the HIAC 9703 sampler, or sited remotely on a networked server
