What is Hiac method?
Light obscuration or Single Particle Optical Sensing (SPOS), is a high-resolution analysis technique capable of detecting a small percentage of outliers. Light obscuration works by passing a dilute stream of particles in a liquid suspension between a light source and a detector.
What is a liquid particle counter?
Liquid particle counting is used to measure the size and distribution of particles in a liquid or on solid samples. The particle distribution and size are measured by irradiating a liquid sample with a laser diode and detecting the scattered light.
Which of the following is called as obscuration technique?
Light Obscuration, also referred to as Single Particle Optical Sensing (SPOS), is an analytical technique of high resolution capable of detecting a small percentage of outliers. It can also be used to obtain an overall size distribution, when operated with proper technique.
How do you test for particulate matter?
There are basically two tests, light obscuration, which uses light blockage to determine the size and count of particulate matter in the solution; and microscopic assay, which is a measurement of un-dissolvable particles or substances present in the solution – usually plastics, metals or dust.
What is the principle of Coulter Counter?
The Coulter principle states that particles pulled through an orifice, concurrent with an electric current, produce a change in impedance that is proportional to the volume of the particle traversing the orifice. This pulse in impedance originates from the displacement of electrolyte caused by the particle.
What is a particle counter used for?
A particle counter is a useful tool for monitoring indoor air quality (IAQ) in clean rooms and workplaces, as a particle counter measures the concentration of particles in the air.
How does a Coulter Counter work?
With a Coulter Counter, an electrolyte containing the cells travels through a small aperture that is connected to an electric current. The count is achieved by observing the changes in voltage detected as either a cell or electrolyte travels through the aperture.
What is obscuration light?
Light obscuration is an analytical technique in which the individual particles in a liquid suspension are placed in-between a laser light source and a detector. The laser light source is used to illuminate the individual particles resulting in a shadow or a blockage of light.
What is meant by particulate matter?
“Particulate matter,” also known as particle pollution or PM, is a complex mixture of extremely small particles and liquid droplets. These particles can be directly emitted from sources such as forest fires, or they can form when gases emitted from power plants, industries and automobiles react in the air.
Which of the following is a viable particulate?
Complete step by step answer: Now, option b) algae they are the diverse group of aquatic organisms. They grow near the water. Therefore, algae are the living organism. Hence, they are viable particulates.
What is Hemocytometer used for?
A device used for determining the number of cells per unit volume of a suspension is called a counting chamber. The most widely used type of chamber is called a hemocytometer, since it was originally designed for performing blood cell counts.
How much is a Coulter Counter?
Handheld Coulter-principle instruments start at less than $3,500 (with the Moxi Flow retailing for slightly less than $10,000). Benchtop counters start at about $12,000 for the qMicro and work their up to about $50,000 for a well-equipped Multisizer 4e.

What can HIAC liquid particle counters be used for?
These liquid particle counters are now being used for monitoring hydraulic fluids, glycols, cleaning solvents, fuels, lubricants, pharmaceuticals, compressed gasses, water and many others. HIAC is the benchmark name in liquid particle counting for laboratories and industrial applications.
What does HIAC stand for in concrete sealer?
USES HIAC (VOC) is used for protection of old or new concrete from weather, chemical attack, staining, and dusting. HIAC (VOC) imparts a medium-to-high sheen, dependent upon the number of coats applied, which enhances the natural concrete colour.

When did HIAC liquid particle counters come out?
HIAC Liquid Particle Counters Get accurate, consistent fluid monitoring with HIAC particle counters 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.
