About

• Particle collection:The sampler draws in air and uses a cyclone separator or impactor to separate particles by size, collecting PM10 and PM2.5 particles on separate filters for gravimetric analysis.
• Gas collection:As air passes through the particle collection stage, it also flows through a sorbent tube or liquid trap to capture gaseous pollutants.
• Data logging:Many modern samplers have digital flow controllers to ensure a constant, accurate flow rate and a data logger to record and store information for later analysis.

• Simultaneous sampling:Collects both particulate and gaseous samples in one event, which is more efficient than separate sampling methods.
• Size-selective:Can separate particles into different size fractions, such as PM10 and PM2.5, which is crucial for assessing health impacts.
• Regulatory compliance:Designed to meet the requirements of various standards, such as those from the CPCB, EPA, and ISO.
• Field flexibility:Many models are portable, battery-powered, or have a weather-resistant body for outdoor use.

• Environmental monitoring:Measures ambient air quality in cities and rural areas.
• Occupational health:Monitors worker exposure to dust, fumes, and vapors in factories and other industrial settings.
• Industrial hygiene:Used to check compliance with workplace safety regulations.
• Agricultural monitoring:Assesses dust generated from activities like tilling, harvesting, and pesticide application.
