Portable Air Sampler for indoor and outdoor sampling for all types of airborne particulates including environmental pollutants, nuclear and biohazards, industrial, governmental and military tests and studies, mine air hazards, factory dusts, chemical, radiological and toxicological analyses, as well as innumerable other types of research, quality control and testing applications.
Principle of Operation
Large volumes of air are drawn through a filter by a high-speed rotary motor. Particulate matter in the air collects on various types and sizes of filter papers including Glass Fiber Filter Media.
Universal motor, Pump, Variable Orifice Flowmeter calibrated 0-70 CFM or 0-2 CMM; 4" ( 10.16 cm ) diameter Filter Holder Assembly, Filter Support Rod and Stainless Steel Mesh Adapter, carrying handle, on/off current toggle switch, 8 foot ( 38 cm ) grounded cordset.
Analysis of Collected Samples
Filters can be analyzed gravimetrically, by weighing, taring, ashing, spectrography, atomic absorption, comparator, microscopic count, chromatography, atomic colorimetric assay, and gammaray spectroscopy, x-ray fluorscopy and neutron activation etc., to identify pollutants and measure their concentrations.
Proper filter is inserted into appropriate filter holder of air sampler and sampler is then ready for test operations. Initial flow rate and sampling time are recorded. Flow rate is governed by size and type of filter used. ( See Chart A Filters )
The Staplex SH4 4" Diameter Filter Holder Assembly, is equipped with filter support rod to be used as back support for Staplex TFA2133 filters. In addition. when using Staplex TFA41 Filter Paper and Staplex TFAGF41 Glass Fiber Filters, a special 4 " Diameter Stainless Steel Screen is required ( included ).
The rate of flow is measured by means of an indirect, variable orifice flow meter (pressure indicator gauge). This indicates the pressure drop across an orifice in the housing and is calibrated against a standard orifice on the intake. Flowrate is determined by saturation of filter paper and should be recorded accordingly during sampling test periods. User can calibrate the flow meter in the field using the US EPA prescribed method for calibrating High Volume Air Samplers, using Staplex Model CKHV and CKHV810 Calibration Kits. (See additional data sheet)
Can be used indoors or outdoors. for mobile or fixed position operation either horizontally or vertically. Also available is a convenient Staplex TR-1 Tripod mounting. When required for protracted periods outdoors a special outdoor enclosed shelter in Aluminum ( SAM ) or Wooden ( SWM ) is available.
TFIA series models can be operated continuously when using TFA810 and TFAGF810 8" x10" filters continuously, with filters checked and changed as need, based on particulate saturation. No lubrication of any motor parts is required. Motor brushes should be check after every 600 hours of usage and changed as needed. Changing of brushes is recommended for every 800 - 1,000 hours of usage.
