TE-PNY1123XZ Mass Flow Controlled PUF Air Sampler

The TE-PNY1123XZ is a high volume air sampler specifically configured for polyurethane foam (PUF) sampling of polycyclic aromatic hydrocarbons (PAHs), pesticides, and volatile organic compounds in ambient air. This apparatus operates at a rate of 4 to 10 scfm (0.114 to 0.285 std m³/min) and is used by EPA for high-volume sampling of ambient air.

Mass Flow Control Technology

The mass flow controller (MFC) maintains a constant volumetric flow rate by automatically adjusting motor speed based on real-time flow feedback. This system compensates for filter loading and environmental conditions throughout the sampling period, ensuring consistent sample collection volumes and improved data quality for regulatory compliance monitoring.

Key Specifications

Power: 220V, 60Hz single phase
Motor: Brush-style motor assembly with proven field reliability
Timer: 7-day mechanical timer with bright yellow dial and on/off trippers
Flow Rate: 4 to 10 scfm (0.114 to 0.285 std m³/min)
Housing: Anodized aluminum shelter for outdoor deployment

Dual-Phase Sampling Design

The sampler uses a dual-media configuration with a glass fiber filter followed by a polyurethane foam cartridge to capture both particulate-bound and vapor-phase contaminants. This method permits collection of both phases and allows for extraction of the filter and sorbent together to permit accurate measurement of semi-volatile organic compounds.

EPA Method Compliance

This sampler is designed for compliance with multiple EPA Compendium methods:

EPA TO-4A for pesticides and PCBs
EPA TO-13A for polycyclic aromatic hydrocarbons
EPA TO-9A for dioxins and furans

Field Operation Features

The mechanical timer provides simple, dependable sampling schedule control without requiring digital programming or battery backup. The timer is set to turn the sampler on and off at desired times, making it ideal for unattended operation in remote monitoring locations. The brush motor design offers field-proven reliability and straightforward maintenance procedures.

Applications

Designed for ambient air quality monitoring programs requiring collection of:

Polycyclic aromatic hydrocarbons (PAHs) for carcinogenic compound assessment
Organochlorine pesticides and herbicides
Polychlorinated biphenyls (PCBs)
Semi-volatile organic compounds (SVOCs) in source assessment studies
Dioxins and dibenzofurans in industrial area monitoring
