Tisch TE-PNY1123 High-Flow PUF Dioxin Sampler

Overview

The Tisch TE-PNY1123 High-Flow PUF Dioxin Sampler is an engineered solution for the quantitative collection of airborne dioxins and furans (PCDDs/PCDFs) from ambient air and stack emissions. Designed in strict accordance with internationally recognized sampling protocols—including ISO 12884, ISO 16362, US EPA Methods TO-4A, TO-9A, TO-13A, and ASTM D6209—the instrument employs a high-efficiency polyurethane foam (PUF) sorbent matrix to capture both gaseous-phase and particle-bound congeners across a broad molecular weight range. Its operation is grounded in isokinetic or non-isokinetic volumetric sampling principles, where precise flow control ensures representative mass loading onto the PUF plug under defined temperature and pressure conditions. The sampler’s robust architecture supports extended-duration deployments (up to 24 hours at maximum rated flow and system backpressure), enabling trace-level analyte accumulation necessary for subsequent HRGC/HRMS analysis at sub-femtogram sensitivity thresholds.

Key Features

• High-flow capability (120–750 L/min) optimized for low-concentration ambient dioxin monitoring and regulatory compliance sampling
• Electronically controlled, closed-loop mass flow regulation with real-time feedback and ±2% stability over time
• Integrated thermal management to minimize condensation and analyte loss during extended sampling campaigns
• Modular PUF cartridge design compatible with standard 110 mm diameter stainless-steel holders and glass fiber filters
• Calibration traceable to NIST-certified flow standards; onboard data logging of flow rate, elapsed time, temperature, and pressure
• Compliance-ready firmware supporting audit trails and electronic record integrity per FDA 21 CFR Part 11 requirements

Sample Compatibility & Compliance

The TE-PNY1123 is validated for use with polyurethane foam (PUF) as the primary adsorbent, and may be coupled with upstream quartz fiber filters (QFF) for concurrent particulate-phase capture. It meets methodological requirements for dioxin sampling under multiple international regulatory frameworks: UNI-EN 1948-1:2006 (stationary source emissions), ISO 12884:2000 (ambient air—gas and particles), ISO 16362:2001 (particulate fraction only), and US EPA Method 23 (stack testing). When deployed with appropriate inlet configurations (e.g., heated probe, cyclonic pre-separator), the system satisfies isokinetic sampling criteria for stack gas applications. All hardware components are constructed from inert, low-outgassing materials (electropolished stainless steel, fluoropolymer seals) to prevent analyte degradation or artifact formation.

Software & Data Management

The sampler integrates with Tisch’s proprietary WinDioxin™ acquisition software, which provides real-time visualization of flow dynamics, automatic correction for barometric pressure and temperature deviations, and export of compliant CSV/Excel reports. Raw data files include timestamps, cumulative volume, instantaneous flow deviation, and alarm flags for out-of-specification events (e.g., flow drift >±3%, power interruption). Audit logs retain operator ID, configuration changes, and calibration history—fully aligned with GLP and GMP documentation expectations. Data exports support direct ingestion into LIMS platforms via ODBC drivers and are structured to meet EPA EQuIS and EU EIONET metadata schemas.

Applications

• Ambient air monitoring networks assessing background dioxin levels near industrial zones, waste incinerators, and landfill sites
• Source testing of municipal solid waste incinerators (MSWIs), cement kilns, and metallurgical facilities per EN 1948 and EPA 23
• Method validation studies requiring high-volume, low-blank collection for congener-specific quantitation
• Long-term trend analysis under national dioxin monitoring programs (e.g., US EPA National Air Toxics Assessment)
• Research-grade exposure assessment in epidemiological field studies where spatial resolution demands high sample throughput

FAQ

What sorbent media are compatible with the TE-PNY1123?

The sampler is optimized for 110 mm diameter PUF plugs; XAD-2 resin cartridges may be used with adapter kits but require flow recalibration and validation per ISO 16000-23.
Does the instrument support isokinetic sampling in stack applications?

Yes—when integrated with a heated sampling probe, pitot tube, and differential pressure transducer, it supports manual or automated isokinetic control per EN 1948-1 Annex B.
How is flow calibration performed and maintained?

Calibration uses a NIST-traceable primary standard (e.g., dry calibrator or bubble meter) at three points across the operating range; annual verification is recommended, with field checks prior to each campaign.
Can the TE-PNY1123 be operated unattended for multi-day sampling?

It supports continuous 24-hour operation at rated max flow; for longer durations, external power conditioning and environmental enclosure are required to maintain thermal stability and data integrity.
Is the device suitable for PCN and PCB co-sampling?

Yes—its flow range and PUF retention efficiency cover polychlorinated naphthalenes (PCNs) and indicator PCBs, provided analytical methods (e.g., EPA 1668C) are applied in the lab.
