Particle Counter

A particle counter is an instrument which detects and counts physical particles. The nature of particle counting is based upon light scattering, light obscuration, or direct imaging. A high intensity light source is used to illuminate the particle as it passes through the detection chamber. The particle passes through the light source, which is typically a laser or halogen light, and if light scattering is used, then the redirected light is detected by a photo detector. If direct imaging is used, a halogen light illuminates particles from the back within a cell while a high definition, high magnification camera records the passing particles.

The recorded video is then analysed by computer software to measure particle attributes. If light blocking (obscuration) is used, the loss of light is detected. The amplitude of the light scattered or light blocked is measured and the particle is counted and tabulated into standardised counting bins.

Direct imaging particle counting employs the use of a high resolution camera and a light to detect particles. Vision based particle sizing units obtain two dimensional images that are analysed by computer software to obtain particle size measurement in both the laboratory and online. Along with particle size, the colour and shape analyses can also be determined.

Types of Particle Counters

There are two major types of particle counters dedicated to counting air-borne or liquid particles.

Aerosol particle counters

Aerosol particle counters are used to determine the air quality by counting and sizing the number of particles in the air. This information is useful in determining the amount of particles inside a building or in the ambient air. It is also useful in understanding the cleanliness level in a controlled environment. For life science and electronic Cleanroom applications, air particle counters are used to classify and monitor cleanliness and to detect airborne viable particles in conformance with ISO 14644-1:2015 Cleanrooms and associated controlled environments — Part 1: Classification of air cleanliness by particle concentration.

Total Clean Air offers a range of Aerosol Particle Counters for Particle Monitoring, with sensitivities from 0.1 µm and flow rates up to 100 litres/minute. Particle counters for air and gas are crucial for the Cleanroom industry. Our powerful and effective air particle sensors and counter technology service many industries such as semiconductor and microelectronics, pharmaceutical and life science, photonics and optics, aerospace and defence, cleanroom research and development.

At Total Clean Air, our remote and portable particle counters for air and gas are specifically designed for Cleanroom environments. Our team manufactures technology that counts the number of particles in the air, and then calculates their results accordingly. By doing so, we measure the cleanliness levels of the Cleanroom and controlled environments for sensitivity and contamination analysis.

Liquid particle counters

Liquid particle counters are used to determine the quality of the liquid passing through them. The size and number of particles can determine if the liquid is clean enough to be used for the designed application. Liquid particle counters can be used to test the quality of drinking water or cleaning solutions, or the cleanliness of power generation equipment, manufacturing parts, or injectable drugs.

At Total Clean Air, our range of particle counters extends to Liquid Particle Counting, which offers a wide range of instrumentation for monitoring particles in liquid, chemical monitoring and parental sampling.
