High Volume PUF Sampler for Toxic Organic Compound Collection

The TE-1000XZ is a high volume air sampler that collects airborne particulate and vapor contaminants using polyurethane foam (PUF) media. These samplers are typically used to collect volatile organic compounds and airborne pesticides for ambient air quality monitoring and environmental assessment.

Dual Collection System

The sampler incorporates a dual sampling module design that captures both particulate matter and gas-phase contaminants. The system incorporates a dual sampling module to collect airborne particulates onto the filter paper media and the vapor elements onto a piece of polyurethane foam in the lower chamber of the sampling module. This design enables comprehensive collection of semi-volatile organic compounds that exist in both phases.

EPA Method Compliance

The TE-1000XZ meets requirements for EPA methods TO-4A, TO-9A, and TO-13A for ambient air sampling. EPA Method TO-13A specifically addresses determination of polycyclic aromatic hydrocarbons (PAHs) in ambient air using gas chromatographic/mass spectrometry (GC/MS), while TO-4A and TO-9A cover pesticides, polychlorinated biphenyls, and other toxic organics.

Key Specifications

Power: 220V, 60Hz configuration
Motor Type: Brush style motor using carbon motor brushes to conduct current within the electric motor
Timer: 7-day mechanical timer recognized by its bright yellow timer dial, using a series of on/off trippers to set the sampling schedule
Flow Rate: 125-250 lpm operating range
Housing: Anodized aluminum shelter that houses the timer, magnehelic gauge, vacuum motor, elapsed time indicator, flow venturi, and dual sampling module

Operation and Control

Standard PUF air samplers use a manual motor speed adjustment device to control the motor speed. The system includes a magnehelic gauge that records the pressure drop through the critical orifice, with this value used to calculate the ambient or standard flow rate. The venturi is a critical orifice used to control the amount of flow through the sample media, with barbed hose fittings to record the differential pressure as it passes through the orifice.

Motor Maintenance

The brush-style motor provides proven field reliability but requires periodic maintenance. Brush motors are low cost but require routine motor brush changes. Regular inspection and replacement of carbon brushes ensures consistent performance and extends motor life.

Applications

This configuration is ideal for:

Ambient air monitoring for toxic organics compliance
Environmental impact assessments
Industrial hygiene monitoring
Research studies requiring EPA-compliant sampling methods
Long-term monitoring programs with scheduled sampling protocols

The TE-1000XZ provides reliable, EPA-compliant collection of both particulate and gas-phase contaminants for comprehensive ambient air quality assessment.
