Dust emissions in the air consist of dust, dirt, soot, smoke and suspended liquid droplets. These particles can also consist of a complex mixture of organic and inorganic substances in the air. Dust is physically characterized by mass concentration and size. Particles larger than 2.5 microns are generally called coarse particles, while those smaller than 2.5 microns are called fine particles. Particles smaller than 10 micrometers in diameter can cause all kinds of health diseases related to heart and lung diseases.
Dust/particle sampling and measurement systems are divided into two groups: ambient air and flue gas. Dust/particle sampling and measurement systems in ambient air are also divided into three groups:
- Continuous dust/particle measuring devices
- PM10 – PM2.5 Dust Particle Sampling devices and
- Personal Dust/Particle Sampling Systems
Continuous dust/particle measurement devices operate on the TEOM and Beta Gage principles, allowing you to see the measurement results instantly on the device. It can be easily used for continuous observation, control and reporting of dust/particle levels.
PM10- PM 2.5 Dust/Particle Sampling devices can be categorized as EN 12341 and EPA PM10 Sampling, Sequence Sampling, Dichotomous (PM10-PM2.5) Sampling, PUF Sampling, Hi-Volume and TSP Dust/Particle Sampling. In these dust/particle sampling systems, particles are collected on filters and results are obtained under laboratory conditions. Devices usually installed outdoors perform sampling at certain intervals using special heads according to the amount of particulate matter to be measured (PM10, PM2.5, PM1).
Personal Dust/particle sampling systems can be used safely for occupational health and safety and medical applications. They are portable, hand-held devices and are preferred for their ease of use.
Dust/particle measurement systems in flue gas are classified into two groups:
- Continuous dust particle measurement systems and
- Isokinetic dust particle sampling systems
Continuous dust particle measurement systems can be divided into various groups according to their measurement principles. These devices are mounted on the chimney where the measurement is to be made and provide continuous monitoring.
