Genetec KB-6120-AC Integrated Ambient Air Sampler

Overview

The Genetec KB-6120-AC Integrated Ambient Air Sampler is an engineered field-deployable instrument designed for simultaneous, synchronized collection of gaseous pollutants and airborne particulate matter (PM) under standardized environmental monitoring protocols. It operates on the principle of regulated volumetric aspiration—using precision-controlled, brushless DC sampling pumps to draw ambient air through interchangeable sampling media: aqueous absorbent solutions (e.g., for SO₂, NOₓ, NH₃, ozone, or B[a]P per HJ 956–2018) and certified filter substrates (quartz, Teflon, or cellulose ester) for gravimetric determination of TSP, PM₁₀, and PM₂.₅ per HJ 618–2011 and HJ/T 93–2013. Its dual-path architecture supports four independent gas channels and two parallel particulate inlets—each with dedicated digital mass flow control—enabling concurrent multi-analyte acquisition without cross-interference. The system integrates real-time metrological correction for ambient temperature, atmospheric pressure, and inlet thermodynamic conditions to compute standardized sampling volumes (e.g., m³ at 25 °C and 101.325 kPa), ensuring traceability to national metrological standards (JJG 956–2013, JJG 943–2011).

Key Features

• 5.0-inch high-brightness TFT color touchscreen with cold-temperature operability (−20 °C to 50 °C), supporting tactile + physical key hybrid input and intuitive Chinese-language UI with graphical workflow prompts
• Four-channel electronic flow control for gaseous sampling (0.1–1.0 L/min range per channel, ±2% full-scale accuracy) and dual independent particulate flow paths (up to 100 L/min each) with automatic pressure/temperature compensation
• Brushless DC sampling pumps delivering stable negative pressure (>−30 kPa), low acoustic emission (10,000 h MTBF)
• Integrated high-energy lithium-ion battery pack enabling ≥8 h continuous operation in standalone mode; seamless AC/DC switchover with auto-recharge capability
• Rain-resistant mechanical housing (IPX4-rated) with sealed connectors, corrosion-resistant aluminum cutting heads (anodized surface, anti-static finish), and color-coded quick-connect tubing system for error-free setup
• Password-protected on-device calibration interface with hierarchical access control (admin/operator roles); audit-trail capable parameter logging for GLP-compliant field use

Sample Compatibility & Compliance

The KB-6120-AC accommodates standard EPA/ISO-compliant sampling configurations: impingers (e.g., midget impingers for formaldehyde), bubblers (for HCl, Cl₂), denuders (for acidic gases), and filter holders conforming to ISO 7708 (PM₁₀) and ISO/CD 25508 (PM₂.₅). It supports both federal reference method (FRM) and federal equivalent method (FEM) particulate samplers when paired with NIST-traceable flow calibrators. All operational parameters—including flow rate, sampling duration, accumulated volume, and environmental metadata—are recorded in accordance with HJ/T 375–2007 and HJ/T 374–2007 requirements. The device meets metrological verification criteria outlined in JJG 956–2013 (air sampler) and JJG 943–2011 (TSP sampler), and its data output structure aligns with China’s national environmental monitoring data reporting framework (HJ 212–2017 protocol).

Software & Data Management

Internal firmware stores up to 10,000 sampling records with timestamp, GPS-derived location (when external module attached), ambient T/P, flow deviation logs, and battery status. Data export is supported via USB 2.0 mass storage mode or Bluetooth 4.2 wireless link (BLE profile compliant with SIG standards). Optional Genetec AirData Suite v3.2 (Windows/Linux) enables automated report generation—including ISO/IEC 17025-aligned uncertainty budgets—and batch validation against HJ 618–2011 weight-change thresholds. Audit trails record all configuration changes with user ID, timestamp, and pre-/post-modification values—supporting FDA 21 CFR Part 11–aligned electronic signatures when deployed in regulated QA/QC laboratories.

Applications

This sampler serves routine and campaign-based monitoring across regulatory, academic, and industrial settings: ambient air quality networks (AQMS), occupational exposure assessments (OSHA/NIOSH-style surveys), source emission characterization (stack/duct interface adaptability), indoor air quality studies (IAQ), and method validation laboratories. Its compact footprint and battery autonomy make it suitable for mobile monitoring platforms (e.g., vehicle-mounted deployments), remote site operations (mountain stations, coastal zones), and emergency response scenarios (chemical spill plume tracking). Researchers utilize its synchronized multi-phase sampling capability for co-located gas–particle partitioning studies, oxidative potential assays, and speciated PM chemical analysis (IC, ICP-MS, GC-MS post-extraction).

FAQ

Does the KB-6120-AC support simultaneous sampling of four different gaseous analytes and two PM fractions?
Yes—four independent gas channels and two dedicated particulate inlets operate concurrently with fully decoupled flow control and real-time compensation.
Is the internal battery replaceable in the field without tools?
No—the battery is sealed and service-replaceable only by authorized Genetec technicians to maintain IPX4 integrity and calibration traceability.
Can raw flow sensor outputs be accessed for third-party software integration?
Yes—via RS-232 serial interface (Modbus RTU protocol) or Bluetooth UART profile; register map documentation available under NDA.
What particulate cut-points are supported out-of-the-box?
Standard configurations include TSP (no cutoff), PM₁₀ (BGI SCC 1.062 or similar), and PM₂.₅ (WINS impactor or GKSS design); custom cyclones may be mechanically adapted.
How is flow calibration traceability maintained during long-term field deployment?
The device accepts periodic verification using NIST-traceable primary calibrators (e.g., dry gas meters, critical orifices); calibration coefficients are stored with cryptographic hash integrity checks.
