Xonteck 911 Portable Summa Canister Sampler

Overview

The Xonteck 911 Portable Summa Canister Sampler is a field-deployable, EPA-compliant gas sampling instrument engineered for quantitative collection and preservation of volatile organic compounds (VOCs) and inorganic gases from ambient air, soil gas, landfill emissions, wastewater treatment off-gases, and hazardous waste site plumes. It operates on the principle of whole-air sampling into electropolished stainless-steel Summa canisters—internally passivated with fused silica and coated with proprietary inert surface treatments—to minimize adsorption, catalytic loss, and memory effects. Designed to fully satisfy U.S. Environmental Protection Agency (EPA) Methods TO-14A and TO-15, the 911 system enables trace-level (pptv–ppbv) VOC analysis via subsequent thermal desorption–gas chromatography/mass spectrometry (TD-GC/MS) or GC-FID workflows. Its architecture prioritizes analytical integrity across diverse environmental matrices, supporting regulatory monitoring programs including Photochemical Assessment Monitoring Stations (PAMS), National Air Toxics Trends Stations (NATTS), and Superfund site characterization.

Key Features

• Fully compliant with EPA TO-14A and TO-15 methodologies for VOC and inorganic gas sampling
• Weather-resistant, lightweight portable chassis (14 lbs / 6.35 kg) optimized for extended field deployment
• Inert wetted path constructed exclusively from electropolished 316 stainless steel, PTFE (Teflon®), and Viton® elastomers—certified for low blank performance and high reproducibility
• Integrated pre-sampling automated purge cycle with user-adjustable flow control (0–95 sccm typical, ±0.3% instantaneous accuracy)
• Optional wind-direction–triggered and wind-speed–activated sampling logic for dynamic emission source tracking
• Front-panel 8-digit LED timer with 0.01-hour resolution and 999,999.99-hour capacity; supports programmable 7-day/24-hour scheduling

Sample Compatibility & Compliance

The 911 sampler accommodates standard 6-L and 1-L Summa canisters (as well as custom-sized canisters upon specification) and maintains compatibility with all major laboratory analytical platforms certified under EPA Method TO-15. All internal surfaces meet ASTM D5466–22 requirements for inertness testing and are validated per EPA Compendium Method TO-14A Annex A for background contamination thresholds (<50 pptv benzene equivalent). The unit is designed for use in GLP-compliant laboratories and supports audit-ready documentation when paired with calibrated flow meters traceable to NIST standards. While not inherently 21 CFR Part 11–compliant (as it lacks electronic signature functionality), its analog timer and mechanical flow control ensure unambiguous, non-editable operational logs suitable for chain-of-custody reporting.

Software & Data Management

The Xonteck 911 is a hardware-only, analog-digital hybrid platform requiring no embedded firmware or proprietary software. All operational parameters—including elapsed sampling time, pump activation status, and pressure readings—are displayed via discrete front-panel indicators. Field data recording is performed manually or integrated into external LIMS systems via standardized log sheets aligned with EPA Form 5600-2 and ASTM D6196–21 templates. Optional accessories include NIST-traceable digital pressure transducers and calibrated mass flow meters with RS-232 output for semi-automated data capture. No cloud connectivity, remote diagnostics, or firmware updates are implemented—ensuring long-term stability and minimizing cybersecurity exposure in critical environmental monitoring applications.

Applications

• Ambient air quality monitoring at PAMS and CASTNET sites
• Soil gas screening and vapor intrusion assessment at brownfield and RCRA-regulated facilities
• Landfill gas composition profiling (e.g., methane, NMHCs, halocarbons, sulfur compounds)
• Emission characterization from industrial stacks, wastewater lagoons, and composting operations
• Method validation studies and inter-laboratory comparison exercises per ISO/IEC 17025
• Emergency response sampling during chemical releases or fugitive emission investigations

FAQ

Does the 911 model support automated sequential sampling across multiple canisters?
No—the 911 is a single-canister, single-event sampler. Sequential multi-canister operation requires external manifold integration and manual valve actuation.
Is calibration certification included with shipment?
Each unit ships with a factory-verified pressure gauge certificate (ANSI Grade B, ±2% full-scale accuracy) and flow controller verification report. NIST-traceable recalibration services are available separately.
Can the 911 be powered by battery in remote locations?
It operates exclusively on 12 VDC input (2 A); users may supply compatible external lithium-ion or lead-acid field batteries with regulated 12 V output and appropriate overcurrent protection.
What maintenance intervals are recommended for field use?
AD B161 diaphragm pump membranes should be inspected every 500 operating hours; PTFE/Viton® seals require replacement annually or after 1,000 sampling cycles, whichever occurs first.
Is the unit suitable for indoor or confined-space sampling?
Yes—its compact footprint (15″ H × 12″ W × 6″ D), low power draw, and spark-free pump design meet OSHA 1910.146 and NFPA 70E requirements for non-hazardous area use.
