Low Volume Sampler LVS

The gas flow is determined physically correctly with pressure and temperature compensation and flows into the control electronics as an adjustable variable. The control is carried out via the MicroPNS control module.

Current State of Knowledge

Spatial distribution of pollutants over time are available only through modelling studies and the validation of models is carried out by means punctual ambient data monitoring resulting in objective difficulty of representativeness at the spatial computational domain on long-term assessments of the sources (for example those industrial). Applying conventional monitoring, long term studies could be characterized by relevant costs of devices and chemical analyses. The study of the spatial distribution of atmospheric PM and of its components is essential for a reliable identification of emission sources, the evaluation of particle dispersion over the territory and the assessment of personal exposure.
FAI Instruments S.R.L has been developed a new very-low volume sampler (HSRS) with the purpose of allowing spatially resolved determination of atmospheric particulate matter (PM) and of its chemical components.
The low-cost, automatic and self-powered device assures long-term (1-2 months) collection of PM on membrane filters, suitable for subsequent chemical analyses.
The Innovative techniques for outdoor/indoor active sampling (Patented), able to ensure representatively of the samples collected using an adequate number of devices for the proposed objectives to obtain:

Isoconcentration maps of the area under investigation;
The system allows to keep reliable cost and thanks to the energy free and its small size could be used for
Characterization of pollutants and identification of sources (risk assessment/human health);
More representative evaluation of exposure concentration (Epidemiologic study).

Validation Of Dispersion Models

With the aim to optimize the analytical costs for micropollutant characterization, also the time sampling should be changed “stretching time” for each sample. Using this modality, the number of samples during long term monitoring, could be reduced and the determination of micropollutants should become easier.
The performances of HSRS sampler have been evaluated by national council of research of Rome during 1 year of field test, compared with reference instruments.
The source apportionment studies and monitoring evaluation, through air quality spatially resolved analyses, has been performed by department of chemistry, Sapienza University of Rome.
In this study particular attention was also paid to the representativeness of sites with respect to each local emission source of PM, as follows:

Power plant for waste treatment.
Domestic biomass heating.
Railway
Very extensive steel plant.
Vehicular traffic

Features

1. The micro sampler works autonomously for long periods of time in areas unattended.
2. By setting the operating capacity to 0.5 l/min will have a consumption of only 0.2w for the intake system.
3. The power is supplied from a power supply system constituted by a rechargeable battery and a small solar panel.
4. A small shield protects the sampler from the sun and rain.
5. The sampler is small and light enough to be easily installed on existing structures:
6. Light poles, railings, balconies, TV antenna in terrace in houses.
7. The sampler is programmable by the use of reading.

Station connected with dedicated software.
Another potential application is for the indoor sampling (domestic, school, museum, hygiene market) and for these applications it is extremely important:

Characteristic of absolute silence
Small and light

The results of the sampling should give fruitful information about the real exposure to a contaminant taking into account not only the outdoor air but also the indoor air quality where a person spent more lifetime.

Data Representation and Configuration of The Windselect

The wind directions are divided into 16 sectors, each sector is summed up in its frequency during the measurement. Likewise, the measured wind speeds are divided into 16 classes. This quickly gives an overview of the measurement results.

Picture above: Display with data and wind direction sectors at Windselect
In the configuration, the cartridges are assigned sectors for background and source. For the 3rd cartridge a threshold level is used. Z.B. below 2 m/s is sampled on the cartridge “calm”. Above this speed, according to the configuration, the cartridges “sector 1” or “sector 2” are divided.

Calibrated impactors for accurate cutpoints

The reflectors of the Windselect system were calibrated against reference materials in the United Kingdom. The cutpoints were set in relation to the number of holes and the average diameter of the holes. This resulted in a modular system that can be adapted to all tasks.
The PM10 impactor advantageously also collects the fraction larger than 10 microns on a filter paper. PM1 and PM2.5 impactors can be easily adapted to the flow rate, the cutpoints correspond to a flow of 4.2 m3/h with 400 holes, by reducing the number of holes, the dust can also be collected at 2.3 m3/h or 1 m3/h.
The pm10 collector for separate collection of the fraction larger than 10 μm is now available as a compact unit with d=47 mm for the fraction < 10 μm, pump and temperature-compensated gas meter. Practical for the rapid review of residents’ complaints.

Integrated System

The instrument for the PMx measurement (i.e., SWAM 5A instruments) gives the 24 h mass concentration average value with a high precision and reliability level, while the optical particle counter gives the suspended particulate matter daily trend, putting in evidence its trend in real time (number and granulometric size).
Such a datum, suitably integrated with the PMx information, can give fundamental indications to determine the correlation factors with the emission sources and their type.
This information makes it possible to analyse special environmental conditions allowing, if needed, to identify eventual corrective activities.
This technological approach is aimed at using the OPC data for their correct functional value, that is as an integration of the PMx concentration data supplied by the monitors.

Stand Alone System

The accurate measurement of this parameter (optical dimension of the particle under examination), being not directly detectable, but based on the transformation of light pulses into electric signals, is connected with the quality of the optical and electronic detection system.
That’s why multichannel OPC system (Integrated Monitoring System) is equipped with a special optical configuration called “wide angle”, based on the principle of the ellipse double focusing, allowing to achieve a very high accuracy level in particle detection.
The OPC system measures the number particles in air by the “Light Scattering” physical principle. This principle is based on the measurement of the light “scattered” by a particle interacting with a light source and proportional to the equivalent diameter of the particle itself.
