Overview
The Thermo Scientific Partisol 2000i and Partisol 2000i-D are U.S. Environmental Protection Agency (EPA)-designated reference and equivalent method particulate matter (PM) samplers engineered for regulatory-grade ambient air monitoring of PM2.5, PM10, and coarse particulate matter (PM10–2.5). These instruments operate on the principle of size-selective inertial separation—utilizing certified cyclonic or impactor-based inlets to segregate airborne particles by aerodynamic diameter—followed by gravimetric analysis of mass collected on standardized 47 mm filters. The 2000i is a single-channel sampler compliant with EPA reference methods for PM2.5, PM10, and coarse PM. The 2000i-D extends this capability with dual independent sampling channels, enabling simultaneous, co-located collection of fine (PM2.5) and coarse (PM10–2.5) fractions using a virtual impactor and two parallel 47 mm filter assemblies. Both models integrate the Activol™ mass flow control system—a thermally compensated, closed-loop mass flow controller (MFC)—to maintain precise volumetric flow rates under variable ambient pressure and temperature conditions, ensuring metrological traceability per ISO/IEC 17025-aligned calibration protocols.
Key Features
- U.S. EPA reference method certification for PM2.5 (RFPS-0498-117), PM10 (RFPS-1298-126), and coarse PM (RFPS-0509-175); equivalent method certification for PM2.5 (EQPS-0509-177), PM10 (EQPS-0311-197), and coarse PM (EQPS-0509-178)
- iSeries intelligent platform featuring enhanced Ethernet connectivity, flash memory expansion (supporting ≥86 days of 5-minute interval data logging), and remote data retrieval via iPort™ software
- Modular mechanical architecture: tool-free pump replacement, single-motion filter exchange mechanism, and field-swappable inlet assemblies (PM2.5 cyclone, PM10 sharp-cut inlet, or virtual impactor for 2000i-D)
- Robust environmental resilience: operational range from −40 °C to +50 °C; IP54-rated enclosure; CE-compliant per EN 61326 for electromagnetic compatibility and safety
- Integrated real-time diagnostics: continuous monitoring of flow deviation, pressure drop across filter media, pump duty cycle, and temperature-compensated volume calculation
Sample Compatibility & Compliance
The Partisol 2000i and 2000i-D accommodate standard 47 mm filter media required by U.S. EPA regulatory protocols—including Teflon® 2 μm pore polytetrafluoroethylene (PTFE) membranes for PM2.5 and PM10 gravimetric analysis, Pallflex® TX-40 quartz fiber filters, and pre-fired quartz or Teflon substrates for speciation studies. Each filter holder maintains strict leak-tight integrity (<0.5% leakage at 25 kPa differential pressure) verified per ASTM D6330 and ISO 7708. The 2000i-D’s virtual impactor achieves a 50% cut-point at 2.5 μm ±0.1 μm with geometric standard deviation (σg) ≤1.2, validated against NIST-traceable polystyrene latex (PSL) aerosols. All flow calibrations are traceable to NIST SRM 2999a (primary standard rotameter) and support multi-point audit procedures compliant with EPA 40 CFR Part 53 Appendix C and ISO 12103-1.
Software & Data Management
Data acquisition and instrument control are managed through the embedded iSeries operating environment, supporting GLP-compliant audit trails with time-stamped event logging (filter change, calibration, error flags). The Activol™ flow management system logs corrected volumetric flow (L/min), temperature (°C), barometric pressure (kPa), and calculated total sampled volume (m³) at user-defined intervals (default: 5 min). Internal non-volatile flash memory retains 32 complete filter sequences—including pre- and post-weighing metadata—and supports export via USB 2.0 or Ethernet to laboratory information management systems (LIMS). iPort™ software enables secure remote configuration, firmware updates, and automated report generation aligned with EPA Form QA-1 and QA-2 requirements. Full 21 CFR Part 11 compliance—including electronic signatures, role-based access control, and immutable audit logs—is achievable through optional Thermo Scientific TraceFinder™ integration.
Applications
- Regulatory compliance monitoring for National Ambient Air Quality Standards (NAAQS) under 40 CFR Part 50
- Long-term trend analysis in state and local air quality surveillance networks (SLAMS, NCore)
- Source apportionment studies requiring synchronized fine/coarse fraction collection
- Method validation and intercomparison campaigns per EPA OTM-11 and ISO 14644-1
- Indoor air quality assessments in occupational health settings where respirable and inhalable fractions must be quantified separately
- Research-grade aerosol characterization in atmospheric chemistry laboratories, including hygroscopic growth and chemical speciation workflows
FAQ
What distinguishes the Partisol 2000i from the 2000i-D?
The 2000i is a single-channel reference method sampler for PM2.5, PM10, or coarse PM individually. The 2000i-D adds a second independent sampling train with a virtual impactor to collect PM2.5 and coarse PM simultaneously on separate 47 mm filters—enabling mass balance closure without temporal misalignment.
Is flow calibration traceable to national standards?
Yes. Activol™ MFCs are factory-calibrated against NIST SRM 2999a and support on-site single- or multi-point audits per EPA 40 CFR Part 53 Appendix C using primary standard flow calibrators.
Can the instrument operate unattended for extended periods?
Both models support fully autonomous operation for up to 30 days with scheduled filter changes, integrated power failure recovery, and watchdog-triggered fault reporting via Ethernet or modem.
Which filter media are EPA-compliant for PM2.5 monitoring?
Teflon® 2 μm PTFE membrane filters (e.g., Pall Gelman T6020) are mandatory for federal reference method PM2.5 monitoring; quartz fiber (Pallflex TX-40) and pre-fired quartz are acceptable for PM10 and speciation applications.
Does the system support remote diagnostics and firmware updates?
Yes. iPort™ software provides secure remote access for real-time status monitoring, configuration changes, and over-the-air firmware upgrades—fully auditable under 21 CFR Part 11 when deployed with Thermo’s validated LIMS interface.
