PERSONAL AIR SAMPLER INTRODUCTION
THERE IS A CHANCE THAT WORKERS AT MANY INDUSTRIAL AND CONSTRUCTION SITES WILL BE EXPOSED TO HAZARDOUS DUST, VAPOURS, AND GASES. SINCE INHALATION IS TYPICALLY THE MOST MAJOR ROUTE OF ENTRY INTO THE BODY, IT IS CRUCIAL TO PAY CLOSE ATTENTION TO THE AIR THEY ARE BREATHING.
IN GENERAL, WE USE A SAMPLE PUMP TO EXTRACT A KNOWN VOLUME OF AIR THROUGH AN APPROPRIATE SAMPLING MEDIA. FILTER PAPER OR OTHER SUITABLE SOLID MEDIUM WOULD BE USED FOR PARTICLES AND FUMES, AND A SORBENT TUBE, OR PERHAPS AN IMPINGER OR BUBBLER, WOULD BE USED FOR GASES AND VAPOURS. WITH THE SAMPLER SITUATED IN THE BREATHING ZONE, A TYPICAL SAMPLING TRAIN FOR PERSONAL MONITORING WOULD RESEMBLE THIS;
Gas sampling bags, like Tedlar bags, are used for collecting samples of gases. Moreover, background exposure can be measured using passive or diffuse sampling methods. They are sealed badges that are sampled, worn on the individual for the specified amount of time, sealed, and then sent off for analysis.
To enable hands-free sampling of inhalable gaseous pollutants and particulate matter in the air actually breathed by the person at work, Personal Air Sample is a battery-operated tiny air sampler that may be fastened on to a person.
Uses include: monitoring fugitive gas emissions in the workplace, workplace air quality, and workplace monitoring. They are also used in places of employment for businesses in the chemical, paint, cement, sugar, and other industries.
Features of the physical design include a holder for the sampling medium, a suction pump, a flow measurement device, a flow controller, and a battery for each personal air sampler.
For sampling of dust or particles, a suitable filter that has been placed in a filter holder serves as the sampling medium. An adsorption tube that is filled with pollutant-specific adsorbents like activated charcoal, tenax GC, etc. serves as the medium for sampling gases and vapours.
The filter or the adsorption tube must be the only one of the two media being utilised at once.
The suction needed to draw air through the sampling media is provided by a low power diaphragm type suction pump. A large capacity rechargeable Li-ion battery powers it. A tiny rotameter that has been carefully built can measure flow.A ball valve, a needle valve, or an electronic circuit can be used to control flow.
A battery-operated model with a rechargeable battery is one of its key features.
Used to monitor the air quality in workplaces or on shop floors. Small and Lightweight, weighing under 500 grammes
To assess TLV exposure, the filter holder or adsorbing tube can be held at the level of inhaling.
May be worn by the user
Model that is lightweight, convenient, and reasonably priced.

High Volume Air Sampler for PM2.5 Global's line of extremely reliable and durable samplers created for capturing particulate matter and gaseous contaminants in ambient air are known as High Volume Air Samplers (HVAS). The High Volume Air Sampler (HVAS) is a piece of equipment used to sample huge amounts of ambient air in order to filter out the particulate matter it contains. Finely divided solids or liquids that are spread in the air from natural sources, industrial operations, or both are referred to as particulate matter. To stop collecting of particles larger than a certain size, a Size Selective Inlet (SSI) is used as a pre-filter. Size Selective Inlet (SSI) PM 2.5 only allows particles with an AED 2.5 micron diameter to enter the collection medium; particles larger than 2.5 microns are not allowed. Features of the physical design: High Volume Air Samplers, such as the PEV-HVS and PEM- RDS series, PM2.5HVS, are made up of a large blower, a filter to catch suspended particles, and a way to gauge the flow rate. Through the side apertures of the SSI, suspended airborne particles are sampled at sampling rates ranging from 1.1 to 1.6 m3/min and collected on a 203 x 254 mm filter paper. Important Features: Electronic Control Module with a Microprocessor; 32-character LCD Module with alphanumeric characters; Electronic Timer Cumulative Totalizer. Continuous Duty Blowers; Settable Delay & Sampling Time The exhaust orifice plate meets with USEPA standards. An optional gaseous sampling attachment for all models. By replacing the gable roof with SSI, it can be transformed into a PM10 sampler. Unique Characteristics: Free flow without resistance at 1.1 to 1.7 Cu m/min flow rate. Particle Size: Depending on the filter being used, down to 0.3 micron. Filter holder made to fit any standard 8 X 10 (20.3 X 25.4 cm) size filter sheet. The GF/A filter is advised for general use, and EPM 2000 for specialised research. Time Totalizer: Record the running time in hours from 0 to 99999.99 hours for sampling time: Automatic Sampling: A 24 hour programmable timer that automatically turns the device on or off after the preset intervals can be easily set. 220 volts, 5 amps, single phase AC power requirements. Rotameter flow rate is measured with a plastic body flow metre with a 2% FSD accuracy between 0 and 3 lpm.
