High-Volume Air Sampler for TSP and PM10

What is the High-Volume Air Sampler for TSP and PM10?

A pump-driven sampler that draws large volumes of ambient air, typically 1.05 m³/min, through a quartz or glass fiber filter for gravimetric determination of total suspended particulates or PM10. It is the right choice for reference filter sampling and for analysis of metals and organics on the collected dust.

Overview

The high-volume sampler consists of a weatherproof shelter, an inlet head, a filter holder for 203 x 254 mm filters, a brushless blower and a mass flow controller or orifice-based flow recorder. Interchangeable PM10 impactor heads or TSP inlets let users adapt the unit to different fractions. The filter is conditioned and weighed before and after sampling on a microbalance with 0.01 mg readability at controlled humidity, and mass divided by sampled air volume gives concentration. Electronic timers run 24-hour sampling runs, and digital flow control compensates for filter loading. The filter can then be extracted for lead, PAH, arsenic or ionic species. Because it is a gravimetric reference, it requires manual handling but offers the highest defensibility.

How does it work?

Air monitors sample air through an inlet and quantify target components by physical or chemical sensing. Particulate instruments use laser light scattering, beta ray attenuation or gravimetric collection on filters, often after a size-selective inlet such as a PM2.5 impactor. Gas sensing uses electrochemical cells, metal oxide semiconductors, non-dispersive infrared absorption, photoionization, or ultraviolet and chemiluminescence analyzers for reference-grade measurements. Active samplers draw air at a controlled flow, for example 16.7 L/min for PM filters or 0.1 to 1 L/min for sorbent tubes and impingers, while passive samplers rely on diffusion. Meteorological sensors record wind, temperature, humidity and pressure to interpret results. A controller logs data, applies calibration factors and communicates over wireless networks.

What are the key features?

• Constant flow control holds 1.05 m³/min despite filter loading changes.
• Interchangeable TSP and PM10 inlet heads adapt one sampler to several fractions.
• Electronic timer and event log support scheduled 24-hour sampling runs.
• Filter holder accepts 203 x 254 mm quartz or glass fiber filters.
• Weatherproof aluminum shelter protects the blower and electronics outdoors.
• Collected filters are suitable for metals, PAH and ion analysis after weighing.

What are the technical specifications?

A typical high-volume air sampler for tsp and pm10 configuration offers sampling flow rate of 1.05 m³/min (adjustable 0.8–1.3), flow accuracy of ±2%, filter size of 203 × 254 mm, PM10 cut point of 10 ± 0.5 µm at rated flow, timer range of 0–99 h, programmable and flow control of Mass flow controller with T/P compensation. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The High-Volume Air Sampler for TSP and PM10 is used in reference TSP and PM10 sampling, heavy metal deposition studies, PAH and organic aerosol analysis and industrial dust compliance. Across the wider Air Monitoring class, laboratories also deploy it for regional air quality networks, indoor air quality assessment and occupational exposure monitoring.

Which standards and certifications apply?

Relevant standards and methods include EN 12341, EN 14211, EN 14212, EN 14625, EN 14626, ISO 7708, US EPA 40 CFR Part 50 and HJ 653. Certification candidates for this model are CE, ISO 9001 manufacturing and RoHS; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Site the inlet away from local sources and obstructions, typically 1.5 to 15 m above ground with a clear airflow, following regulatory siting criteria. Use inert sampling lines such as PTFE for reactive gases and keep them short. Calibrate gas analyzers with certified standards and zero air, and verify flow rates on samplers with a traceable flow meter. Replace filters, pump diaphragms and sensor cells on schedule, and protect instruments from condensation and extreme temperatures with shelters or enclosures. Sensor-based devices drift with humidity and temperature, so collocate with a reference periodically. Document all events, because flagged data is required for validation and for any compliance reporting.

How do I select the right High-Volume Air Sampler for TSP and PM10?

Select a high-volume sampler when gravimetric reference results or chemical analysis of the collected dust are required. It gives no real-time data, unlike laser or beta monitors. In an RFQ, specify TSP and PM10 heads, flow control type, filter size, timer features, shelter and calibration orifice requirements.

How does it compare with other Air Monitoring variants?

Define the pollutants, the required accuracy and the decision the data supports. Regulatory networks need reference or equivalent analyzers, while screening, mapping and community monitoring can use sensor-based units with periodic collocation. For exposure assessment of workers, personal pumps with sorbent tubes or filters are required. Indoor air quality investigations usually use handheld instruments for CO2, temperature, humidity, VOC and particulates. Check range, detection limit, response time, humidity compensation and operating temperature. Consider calibration effort, consumables, power availability and communication. For mobile surveys, consider battery life, GPS and weight. Confirm that the supplier provides calibration certificates and data formats compatible with your reporting platform.
