Details

Description

Select toxic organic compounds in ambient air are sampled with a modified high volume air sampler using a combination of quartz filter and sorbent cartridge with subsequent analysis by gas chromatography with mass spectrometry detection.

 

Overview

A wide variety of sorbents can be used in a manner that permits their continual use. Polyurethane foam or wet/dry granular solid media can be used individually or in combination. 

The dual chambered sampling module is designed for easy access to both upper and lower media. The threaded lower canister is removed with the cartridge intact for immediate exchange. Filter support screens and module components are equipped with gaskets providing a leak-proof seal during the sampling process. 

Air flow rates are infinitely variable up to 280 liters per minute. The voltage variator adjusting screw alters the blower motor speed to achieve the flow rate desired. Air flow rate is measured through the flow venturi utilizing a 0-100" magnehelic gage. Periodic calibration is necessary to maintain on-site sampling accuracy. 

A seven-day mechanical timer is included as standard equipment and permits weekly scheduling with individual settings for each day and 14 trippers to turn the sampler “On” and “Off” as desired. Any day or days may be omitted. Day and night periods are distinctly marked. 

A nonresettable, elapsed time indicator verifies cumulative, intermittent sampling time periods as well as total elapsed time of operation. Calibrated in tenths-of-a-minute, the unit has a total register of 99,999.9 minutes. 

The calibration kit includes a manometer and calibration orifice with curve supplied in a carrying case. The calibration orifice attaches directly to the top of the filter holder eliminating the need to disassemble the sampling unit. 

mass flow controlled PUF sampler is available which incorporates an 8 x 10-inch filter holder and mass flow controller into the standard PUF housing. The flow rate is regulated between 15 to 25 CFM (424 to 707 lpm) through a 6-inch spool piece equipped directly with polyurethane foam or a glass cartridge with polyurethane foam. 

APPLICATIONS

  • Determining common pesticides & polychlorinated biphenyls (PCBs), TO-4A
  • Determining polyhalogenated dibenzo-p-dioxins & dibenzofurans (PHDDs/PHDFs), TO-9A
  • Determining common polycyclic aromatic hydrocarbons (PAHs), TO-13A

 

Design

A dual chambered aluminum sampling module contains two filtering systems. The upper chamber supports the airborne particulate filter media in a circular filter holder. The lower chamber encapsulates a glass cartridge which typically contains the polyurethane foam (PUF) for vapor entrapment.
