Tisch TE-6070 High-Volume PM₁₀ Air Sampler

Overview

The Tisch TE-6070 High-Volume PM₁₀ Air Sampler is an EPA-designated reference method instrument engineered for regulatory-grade ambient air monitoring of inhalable particulate matter with an aerodynamic diameter ≤10 µm. It operates on the principle of inertial separation using a certified PM₁₀ size-selective inlet (EPA-approved sharp-cut cyclone), followed by gravimetric collection onto standardized 8″ × 10″ (203 mm × 254 mm) filter media under controlled volumetric or mass-based flow conditions. The system adheres strictly to U.S. Environmental Protection Agency (EPA) Reference Method RFPS-0202-141 and satisfies all performance criteria outlined in 40 CFR Part 50, Appendix L for PM₁₀ monitoring networks. Its robust architecture integrates precision flow control, real-time pressure monitoring, and time-synchronized sampling—ensuring data integrity required for compliance reporting under federal, state, and tribal air quality programs.

Key Features

• EPA-compliant PM₁₀ size-selective inlet with validated 50% cut-point at 10 µm ±0.5 µm aerodynamic diameter, traceable to NIST standards
• Dual flow control architecture: configurable with Volume Flow Controller (VFC, model TE-10557) or Mass Flow Controller (MFC, model TE-300-310) for temperature- and pressure-compensated operation
• Stainless steel 8″ × 10″ filter holder (TE-6003) with integrated stagnation pressure port for simultaneous flow verification and leak testing
• Alumina protective housing (TE-6002) providing thermal stability, UV resistance, and corrosion protection in outdoor deployments
• Continuous analog flow/pressure recorder (TE-5009) with chart-based documentation for audit-ready traceability
• 30-inch water manometer (TE-6001) for field verification of pressure drop across the filter medium and inlet assembly
• Modular timer options: 7-day mechanical timer (TE-5007), digital timer (TE-302), or smart Plus-series controller (TE-300-312) with programmable start/stop logic and event logging
• 1 HP, 2-pole vacuum blower motor (TE-5070 or brushless TE-5070-BL) delivering stable 40 CFM (1.13 m³/min) nominal flow with low vibration and extended service life

Sample Compatibility & Compliance

The TE-6070 supports all EPA-accepted 8″ × 10″ filter media, including quartz fiber (TE-QMA, TE-QMA-100), glass fiber (TE-G653), and cellulose ester (TE-241) substrates. Each filter type is certified for compatibility with subsequent laboratory analysis—including gravimetric mass determination, elemental carbon (EC)/organic carbon (OC) speciation via thermal-optical transmission (TOT), and ICP-MS quantification of metals. The system meets full requirements for GLP-compliant data acquisition and is routinely deployed in State and Local Air Monitoring Stations (SLAMS) and National Core (NCore) networks. All hardware components are manufactured to ISO 9001-certified processes, and calibration procedures align with EPA Guidance Document QA/G-5 and ASTM D1357 (Standard Practice for Sampling Air for Particulate Matter).

Software & Data Management

While the base TE-6070 is analog-featured, its digital variants (D- and P-Series) integrate RS-232 or USB interfaces for direct connection to PC-based data acquisition systems. Optional software packages support automated calibration log generation, flow deviation alerts, and export of time-stamped flow/pressure records in CSV or XML format compliant with EPA Air Quality System (AQS) submission schema (AQ-10). Audit trails include operator ID, calibration date, flow setpoint, and environmental parameters (T, P, RH)—fully satisfying 21 CFR Part 11 electronic record requirements when paired with validated secure login and electronic signature modules.

Applications

• Regulatory PM₁₀ monitoring for State Implementation Plans (SIPs) and Prevention of Significant Deterioration (PSD) permit compliance
• Long-term trend analysis in urban, rural, and background airsheds per EPA’s National Air Toxics Assessment (NATA) framework
• Source apportionment studies requiring high-volume, time-integrated samples for receptor modeling (e.g., PMF, CMB)
• Method validation and inter-laboratory comparison exercises under ISO/IEC 17043 proficiency testing schemes
• Field evaluation of new PM₁₀ inlets and filtration technologies against EPA reference benchmarks

FAQ

What EPA reference method does the TE-6070 comply with?
The TE-6070 is designated under EPA Reference Method RFPS-0202-141 and fully satisfies the performance specifications in 40 CFR Part 50, Appendix L for PM₁₀.
Can the TE-6070 be used for PM₂.₅ sampling?
No—the TE-6070 is configured exclusively for PM₁₀. For PM₂.₅, Tisch offers the TE-6071 with a WINS impactor inlet and corresponding flow calibration.
Is the TE-6070 compatible with remote telemetry or SCADA integration?
Yes—when equipped with the Plus-series (P-Type) controller (TE-300-312), it supports Modbus RTU and analog 4–20 mA output for integration into centralized environmental monitoring platforms.
What calibration standards are recommended for routine field verification?
Tisch recommends the TE-5028 primary flow calibrator for C/D models and the TE-5025HVP high-velocity calibrator for P-Series units, both traceable to NIST SRM 1620a.
Does the system require external power conditioning?
A dedicated 120 VAC, 20 A circuit is required; surge suppression and voltage regulation are advised for continuous operation in variable-grid environments.
