Tisch TE-6070 Online High-Volume Particulate Matter Sampler

Overview

The Tisch TE-6070 Online High-Volume Particulate Matter Sampler is an EPA-certified, field-deployable instrument engineered for regulatory-compliant ambient air monitoring of total suspended particulates (TSP), PM₁₀, and PM_2.5. Designed and manufactured in the United States by Tisch Environmental—a leader in air sampling instrumentation with over five decades of experience—the TE-6070 implements high-volume isokinetic sampling principles to ensure representative collection of airborne particulate mass across diverse environmental and occupational settings. Its core architecture supports both volumetric flow control (VFC) and mass flow control (MFC) configurations, enabling precise adherence to U.S. EPA Reference Method RFPS-0202-141 and complementary international standards including ISO 7708 (airborne particles) and EN 12341 (PM₁₀ and PM_2.5 reference methods). The sampler operates continuously under extreme ambient conditions—from arctic cold to desert heat—and maintains stable flow performance across elevation gradients up to 10,000 feet above sea level.

Key Features

• EPA Reference Method RFPS-0202-141 certification for PM₁₀ and TSP sampling—validated for compliance with U.S. National Ambient Air Quality Standards (NAAQS) and equivalent regulatory frameworks worldwide.
• Dual flow control architecture: Volume Flow Control (VFC) model uses calibrated rotameter-based feedback; Mass Flow Control (MFC) model integrates a precision thermal mass flow controller (TE-300-310) with adjustable range of 20–60 cfm (0.57–1.69 m³/min), ensuring consistent volumetric delivery regardless of temperature, pressure, or humidity fluctuations.
• Modular timer and control options: Select from Common (C), Digital (D), or Plus (P) electronic controllers—each supporting programmable multi-interval sampling schedules, real-time flow/pressure logging, and audit-ready run-time tracking via integrated TE-5012 runtime indicator.
• Robust mechanical design: Dual-stage vacuum pump systems (1.0 HP for VFC; 0.6 HP for MFC), optimized for low-maintenance operation in unattended field deployments. Brushless motor variants available for extended service life and reduced electromagnetic interference.
• Standardized filtration interface: Accommodates 8″ × 10″ quartz fiber filters (TE-QMA), compatible with gravimetric analysis, elemental carbon determination (EC/OC), and subsequent ICP-MS or XRF quantification per EPA Methods IO-3.2, IO-4.2, and TO-13A.

Sample Compatibility & Compliance

The TE-6070 is validated for use with certified reference filters meeting ASTM D1357 and ISO 10977 specifications. Its inlet geometry and flow profile comply with EPA’s designated criteria for coarse and fine fraction separation when paired with WINS impactors or BGI SCC 1.062 cyclones (for PM_2.5). All configurations meet GLP requirements for data traceability, with optional analog/digital output interfaces supporting integration into centralized SCADA or EPA AirNow-compatible telemetry networks. The instrument satisfies key elements of 21 CFR Part 11 for electronic records when used with validated Plus (P)-series controllers and timestamped audit logs.

Software & Data Management

While the TE-6070 operates as a stand-alone hardware platform, its Digital (D) and Plus (P) variants support serial RS-232 or optional USB-to-serial communication for external data acquisition. Tisch-provided firmware enables export of time-stamped flow, pressure differential, and runtime metrics in CSV format—structured for direct ingestion into LIMS platforms or statistical analysis tools such as R or Python pandas. The Plus controller includes non-volatile memory for ≥30 days of continuous 1-minute interval logging, with built-in checksum validation and tamper-evident timestamps aligned to UTC. All firmware revisions undergo internal verification against NIST-traceable flow calibration standards.

Applications

• Ambient air quality monitoring networks (e.g., state/local AQMDs, EPA Core Sites, EEA EMEP stations)
• Source apportionment studies requiring co-located PM_2.5/PM₁₀ mass and speciation data
• Occupational exposure assessment in mining, construction, and agricultural pesticide application zones
• Long-term epidemiological cohort studies where filter-based gravimetric consistency is critical
• Validation of low-cost sensor networks through collocated reference-grade sampling
• Regulatory compliance testing for industrial stack emissions and fugitive dust controls

FAQ

Is the TE-6070 compliant with current U.S. EPA requirements for PM_2.5 monitoring?
Yes—the TE-6070, when configured with an EPA-certified PM_2.5 size-selective inlet (e.g., BGI SCC 1.062) and operated per RFPS-0202-141, meets the performance criteria outlined in 40 CFR Part 53 for federal reference method (FRM) samplers.
Can the TE-6070 be deployed at high-altitude locations?
Yes—its flow control systems are explicitly rated for stable operation up to 10,000 ft above sea level, with pressure-compensated MFC models recommended for sites >5,000 ft.
What filter media are supported beyond TE-QMA quartz fiber?
While TE-QMA is the default and EPA-recommended medium, the sampler accommodates other 8″ × 10″ substrates—including PTFE membrane filters (for ion chromatography), cellulose ester (for microscopy), and PVC-backed glass fiber—provided they meet minimum tensile strength and pressure-drop specifications per ISO 9001:2015 Annex C.
Does Tisch provide calibration services traceable to NIST standards?
Yes—Tisch offers factory calibration using primary-standard dry calibrators (e.g., Bios International 3000 Series) with NIST-traceable certificates valid for 12 months, including full uncertainty budgets per ISO/IEC 17025.
Is remote diagnostics or firmware update capability available?
Firmware updates require local physical access via USB or serial interface; however, the Plus (P) controller supports Modbus RTU protocol for integration into facility-wide building management systems (BMS) with remote status polling.
