The TE-PUFPLUSX is a high-volume air sampler designed for collecting volatile organic compounds and airborne pesticides using polyurethane foam (PUF) sampling media. This system meets the requirements described in US EPA methods TO-4A, TO-9A, and TO-13A, which are the standard reference methods for toxic organic compound sampling in ambient air.

PLUS Technology Flow Control

The PLUS technology flow controller uses ambient temperature, ambient pressure, and the orifice differential pressure to maintain the set flow rate, providing the most accurate flow control available for PUF sampling applications. It utilizes a microprocessor based controller for instantaneous and accurate flow control, with built-in temperature and barometric pressure sensors that allow the system to accurately calculate the flow rate.

Key Specifications

Power: 220V, 50Hz configuration for international applications
Motor: Brush-style motor with proven field reliability
Timer: Digital timer with battery backup for uninterrupted operation
Data Logging: Four independent data logs with USB export capability
Environmental Sensors: Built-in ambient temperature and barometric pressure monitoring

Dual Sampling System

The sampler incorporates a dual sampling module design that collects 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 configuration ensures complete capture of both particulate-bound and gas-phase contaminants for comprehensive air quality assessment.

Data Management and Control

The PLUS technology flow controllers include a built in digital timer with internal battery backup, multiple elapsed time indicators, and four data logs with an external USB drive for data retrieval. The system data logs record the average, minimum, and maximum ambient temperature and barometric pressure as well as the total ambient and standard flow rate. This comprehensive data collection supports EPA compliance documentation and quality assurance requirements.

Applications

This PUF sampler configuration is essential for environmental monitoring programs requiring measurement of semi-volatile organic compounds (SVOCs), including pesticides, polycyclic aromatic hydrocarbons (PAHs), and other toxic organic compounds in ambient air. The system supports regulatory compliance monitoring, source assessment studies, and long-term air quality surveillance programs.

Motor and Maintenance

Brush Style motors use carbon motor brushes to conduct current within the electric motor. They are low cost but require routine motor brush changes. The 220V/50Hz power configuration makes this unit suitable for international deployment where this power standard is used.
