The TE-PNY1123-BL is a high-volume air sampler specifically configured for polyurethane foam (PUF) collection of volatile organic compounds (VOCs) and pesticides in ambient air. This system collects both airborne particulate and vapor contaminants, making it ideal for sampling volatile organic compounds and airborne pesticides. The PUF configuration meets the requirements described in US EPA methods TO-4A, TO-9A, and TO-13A, which are the standard reference methods for determination of toxic organics in ambient air.

Dual Sampling Technology

The sampler incorporates a dual sampling module design that captures both particulate and vapor-phase contaminants simultaneously. The system 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. The sampling module consists of a filter and a glass sampling cartridge containing the PUF utilized to concentrate PAHs from the air. This configuration ensures comprehensive collection of semi-volatile organic compounds (SVOCs) that exist in both particulate and gas phases.

Mass Flow Control (MFC) System

The integrated MFC maintains consistent volumetric flow rates by automatically adjusting motor speed based on real-time flow feedback. This control system compensates for filter loading and changing atmospheric conditions during sampling events, ensuring accurate flow measurement for EPA-compliant sample collection. The sampler operates at flow rates between 125 and 250 liters per minute (lpm), with the MFC providing precise regulation throughout the sampling period.

Brushless Motor Advantages

Brushless motors do not use motor brushes or require maintenance. They are higher in cost and do not have any emissions. This eliminates the need for periodic brush replacement and reduces potential contamination from motor brush particles. The brushless design provides consistent performance over extended deployment periods, making it ideal for long-term monitoring programs and remote sampling locations.

Mechanical Timer Operation

The 7-day mechanical timer uses a series of on/off trippers to set the sampling schedule. This dependable timing system allows for precise control of sampling periods without requiring external power or digital programming. The mechanical design provides reliable operation in harsh environmental conditions where electronic timers might fail.

Applications

The TE-PNY1123-BL is designed for ambient air quality monitoring programs requiring collection of:

Volatile organic compounds (VOCs) and pesticides
Polycyclic aromatic hydrocarbons (PAHs)
Semi-volatile organic compounds (SVOCs)
Persistent organic pollutants (POPs)

Common applications include environmental monitoring for regulatory compliance, source assessment studies, and air toxics surveillance programs. The EPA-compliant design makes this sampler suitable for NAAQS monitoring networks and state environmental agency programs.

EPA Method Compliance

This configuration specifically supports EPA TO-13A for determination of polycyclic aromatic hydrocarbons, TO-4A for volatile organic compounds, and TO-9A for pesticides and other semi-volatile compounds. The dual sampling approach ensures collection efficiency for compounds spanning a wide range of volatilities, from gas-phase organics to particle-bound species.
