Table of ContentsWhat kinds of monitoring can the MiniVol do? What is the MiniVol TAS?The MiniVol Tactical Air Sampler is a low-volume, battery powered, filter-based Particulate Matter (PM) sampler developed by Airmetrics. In filter-based samplers, size-sorted particles are captured on a filter that is then weighed ('gravimetric analysis') to determine the concentration of particulate matter in the air pumped through the monitor (see more in the wiki). The MiniVol is designed for 24-hour samples that correspond with Federal Reference Method (FRM) monitors, but due to their lower air volume are not considered FRM-grade. Public Lab has two MiniVols that can be loaned out for monitoring. The MiniVol comes with chargers, outdoor mounts, and consumables neatly mounted inside its shipment-ready box: Outdoor mounts:
Clockwise from top: Minivol, PM2.5 impactor, PM10 impactor, manual, battery pack. How the MinVol worksThe minivol has two different impactors, one for PM2.5, and one for PM10 (pictured up top, on the right). Impactors work to inertially sort particles: __ The MiniVol impactor: Because the MiniVol uses filters and an impactor, it must have the grease on its impactor plate replaced and cleaned every five sample periods, and it requires a new filter for every sample.
What kinds of monitoring can the MiniVol do?The MiniVol collects Particulate Matter (PM) on a filter for analysis. It is designed for monitoring PM10 or PM2.5 over 24 hours. It cannot measure both PM10 and PM2.5 at the same time. Filters may be subjected to different types of analysis to speciate (identify) what the PM is made of. The MiniVol samples a smaller volume of air than a Federal Reference Method monitor and has the best correspondence with FRMs at moderate-high PM concentrations. Filters may be subject to several different types of analysis. Different analysis procedures require different types of filters, and the analysis procedure must be decided ahead of time. Airmetrics' recommended lab is:
Types of analysis offered:
For analyis of crystalline silica, Chester LabNET recommends:
Organics analysis (combustion-related pollution) may be available from: Prices quoted here are estimates and do not reflect actual lab prices. Gravimetric analysis (weighing the filter) is the most basic analysis to which other procedures are added. XRF for metals therefore costs $95 (Gravimetric analysis + XRF). how is the MiniVol used?To deploy a MiniVol requires several steps outlined in the activities below. The MiniVol requires maintenance: once-yearly calibration and a cleaning every five sampling periods. To deploy the MiniVol in the field requires identifying a monitoring site and installation location, pre-deployment preparation, deployment, and analysis of laboratory results. Many calculations in the activities require calculations. All equations in the MiniVol manual are implemented in the following Open Document Format spreadsheet: The spreadsheet was created with LibreOffice Activities[activities:minivol] |
