Overview
The SKC DPS-PM2.5 Deployable Particulate Matter Sampler is a field-deployable, battery-powered ambient air sampling system engineered for high-reliability gravimetric measurement of inhalable fine particulate matter (PM2.5) in accordance with U.S. EPA Reference Method PS-1 and ISO 7708:1995. Based on inertial impactor separation principles, the DPS-PM2.5 employs a precision-machined, stainless-steel PM2.5 cyclonic impactor head that achieves sharp-cut aerodynamic size selectivity at 2.5 µm (50% cut-point) under nominal 3.5 L/min flow conditions. Designed to meet U.S. Department of Defense operational requirements, the system integrates a programmable Leland Legacy sampling pump, high-capacity lithium-ion power architecture, and a fully sealed, weather-resistant transport case — enabling rapid deployment in remote, unattended, or austere environments without external power infrastructure.
Key Features
- Compact, all-in-one integrated design: Pump, impactor head, filter cassette holder, and accessories housed within a single ruggedized, splash-resistant carrying case weighing only 6.1 kg (13.5 lbs)
- Leland Legacy programmable pump with intuitive 3-button interface for autonomous operation — supports time-weighted, multi-stage, or continuous sampling protocols up to 24 hours
- High-energy lithium-ion battery pack delivering stable 3.5 ± 0.1 L/min flow rate over full discharge cycle; compatible with optional AC adapter for extended stationary use
- Disposable, pre-assembled impactor substrate — eliminates post-sampling cleaning, oiling, or calibration drift associated with reusable substrates
- Quick-connect tubing system with standardized ¼-inch barbed fittings for tool-free assembly and leak-minimized connections
- Modular PM2.5 impactor head (included) and optional PM10 head available — both compliant with ISO 10993 biocompatibility standards for filter media contact surfaces
- Rain cap included for outdoor exposure; IP54-rated case enclosure ensures protection against dust ingress and water splashing during field operation
Sample Compatibility & Compliance
The DPS-PM2.5 is validated for use with standard 37-mm or 47-mm diameter membrane filters (e.g., PTFE, PVC, quartz fiber) meeting ASTM D1357 and ISO/IEC 17025 traceability requirements. Filter cassettes are secured using a spring-loaded, tool-free holder with positive-locking mechanism to prevent lateral displacement during transport or high-wind sampling. The system complies with U.S. EPA Compendium Method IO-3.2 for PM2.5 gravimetric analysis and supports data integrity requirements under GLP and ISO 17025-accredited laboratory workflows. All firmware and DataTrac software configurations adhere to FDA 21 CFR Part 11 electronic record and signature guidelines when used in regulated environmental monitoring programs.
Software & Data Management
The DPS-PM2.5 is fully programmable via SKC’s DataTrac v4.2 desktop software (Windows-compatible), enabling advanced scheduling, real-time flow logging, event-triggered sampling, and automated report generation in PDF or CSV format. DataTrac provides full audit trail functionality including user login timestamps, parameter change history, and calibration event tracking — essential for regulatory submissions to EPA, state environmental agencies, or third-party accreditation bodies. Pump runtime, cumulative volume, and pressure drop diagnostics are stored onboard and retrievable post-sampling via USB interface. No cloud dependency or subscription licensing is required; all configuration files are locally encrypted and exportable for chain-of-custody documentation.
Applications
- Ambient air quality monitoring networks requiring portable, low-maintenance PM2.5 reference-grade samplers
- Military base environmental surveillance and occupational exposure assessment per ACGIH TLV® and NIOSH REL guidance
- Construction site perimeter monitoring and fugitive dust source attribution studies
- Community-based citizen science initiatives where ease of use, portability, and cost-effectiveness are critical
- Short-term compliance testing for EPA National Ambient Air Quality Standards (NAAQS) PM2.5 attainment demonstrations
- Indoor air quality investigations in schools, healthcare facilities, and industrial workplaces
FAQ
What filter types are compatible with the DPS-PM2.5 system?
Standard 37-mm or 47-mm diameter filters including polytetrafluoroethylene (PTFE), polycarbonate (PC), mixed cellulose ester (MCE), and quartz fiber — all must meet ASTM D1357 pore structure and loading capacity specifications.
Does the system include flow calibration capability?
Yes — the Leland Legacy pump features built-in volumetric flow calibration traceable to NIST standards; optional external primary calibrators (e.g., dry gas meters or bubble flowmeters) may be used for field verification per EPA 40 CFR Part 53.
Can the DPS-PM2.5 operate continuously beyond 24 hours?
No — the integrated lithium-ion battery is rated for up to 24 hours at 3.5 L/min; for longer durations, an AC power adapter or external power bank with regulated 12 V DC output is required.
Is the impactor head reusable?
No — the DPS-PM2.5 uses a single-use, pre-aligned impactor substrate to ensure consistent collection efficiency and eliminate cleaning-related variability.
How is data security ensured during remote deployments?
All sampling logs are stored locally in non-volatile memory with timestamped entries; DataTrac software enforces role-based access control and generates SHA-256 hashed audit reports compliant with ISO/IEC 17025 Clause 7.11.
