2B Technologies Model 106M UV Absorption Ozone Analyzer

Overview

The 2B Technologies Model 106M is a laboratory-grade, portable ozone (O₃) analyzer engineered for high-fidelity, real-time quantification of gaseous ozone across environmental, industrial, and research applications. It operates on the well-established principle of ultraviolet absorption spectroscopy at 254 nm—a method traceable to NIST standards and widely accepted under ASTM D5012 and ISO 13964 for ozone measurement. Unlike electrochemical or semiconductor-based sensors, the Model 106M delivers inherent specificity to ozone without cross-sensitivity to NO₂, SO₂, or VOCs, ensuring metrological integrity in complex matrices. Its extended dynamic range—from 1.5 ppbv to 1000 ppmv—enables seamless deployment from ambient air quality monitoring (e.g., urban background stations) to high-concentration process control (e.g., ozone generator output validation). The instrument’s low power consumption (4.2 W nominal), compact footprint, and battery-compatible DC input make it suitable for unattended field operation, including solar-powered remote sites with constrained energy budgets.

Key Features

• UV photometric detection at 254 nm with dual-beam optical design for drift compensation and long-term stability
• High-resolution digital signal processing yielding 0.01 ppmv resolution and repeatability better than ±0.5% over 30 days
• Integrated DewLine™ Nafion® dryer tube for active water vapor management—eliminates humidity-induced spectral interference without consumable desiccants
• Configurable sampling interval (10 s native) with on-board averaging options (10 s, 1 min, 5 min, 1 hr) to optimize data density versus storage longevity
• On-device non-volatile memory storing up to 12,288 data points—supporting >1.4 years of hourly averaged records
• Dual analog outputs (0–2.5 V and 4–20 mA) with user-selectable full-scale ranges (0–1, 0–10, or 0–100 ppmv), compliant with SCADA and PLC integration requirements
• Comprehensive LED status system indicating operational state, elevated ozone exposure (>100 ppb), calibration due date, and particulate filter service interval

Sample Compatibility & Compliance

The Model 106M is designed for direct analysis of ambient air, indoor air, and process gas streams containing ozone. Its sample inlet accommodates standard 1/4″ OD tubing and supports flow rates of approximately 1 L/min—optimized for laminar flow conditions that minimize residence time artifacts. The analyzer meets key regulatory and quality framework expectations: its measurement methodology aligns with EPA Reference Method EQOA-01 for ozone, and its data handling architecture supports audit-ready logging per FDA 21 CFR Part 11 when paired with validated software configurations. For GLP/GMP environments—including pharmaceutical cleanroom sterilization validation—the instrument’s factory calibration certificate (NIST-traceable), configurable alarm thresholds, and timestamped event logging provide documented evidence of measurement integrity. All firmware and calibration procedures are version-controlled and field-upgradable via USB.

Software & Data Management

Data acquisition and configuration are managed through 2B Technologies’ proprietary EnviroSoft™ desktop application (Windows/macOS compatible), which enables real-time visualization, remote parameter adjustment, and export to CSV or Excel formats. Raw sensor readings, averaged values, diagnostic flags (e.g., lamp intensity, cell temperature), and calibration metadata are stored with microsecond-precision timestamps. For enterprise integration, the RS-232 and USB interfaces support Modbus RTU protocol, allowing bidirectional communication with building management systems (BMS) or centralized environmental monitoring platforms. All analog outputs include galvanic isolation and are calibrated to ±0.1% FS accuracy. Internal clock synchronization supports NTP via optional Ethernet gateway modules—ensuring temporal coherence across distributed sensor networks.

Applications

• Long-term ambient ozone monitoring in remote or off-grid locations where power availability is limited
• Urban and suburban air quality networks requiring EPA-compliant, low-maintenance analyzers
• Validation and routine verification of ozone-generating equipment—including ozone chambers, sterilization cabinets, and industrial ozonators
• Cleanroom qualification and routine monitoring in pharmaceutical, biotech, semiconductor, and food manufacturing facilities per ISO 14644 and EU GMP Annex 1
• Personal exposure assessment studies investigating dose–response relationships between ozone concentration and respiratory health endpoints
• Calibration transfer and field reference use for lower-cost sensor networks requiring periodic bias correction

FAQ

What is the lower detection limit of the Model 106M?

The instrument achieves a practical detection limit of 1.5 ppbv under typical operating conditions, defined as three times the standard deviation of zero-air measurements.
Does the Model 106M require daily zero/span calibration?

No. Its dual-beam optical architecture and thermally stabilized UV source enable stable operation for up to 30 days between calibrations; however, quarterly NIST-traceable calibration is recommended for regulatory compliance.
Can the Model 106M operate on battery power?

Yes—it accepts 12 V DC input and draws only 350 mA, making it compatible with sealed lead-acid or lithium-ion power banks commonly used in field deployments.
Is the Nafion® dryer replaceable by the end user?

Yes. The DewLine™ module is a field-serviceable component with a typical service life of 12–18 months depending on inlet humidity exposure.
How is data security and audit trail ensured in regulated environments?

When used with validated EnviroSoft™ configurations, all data modifications, calibration events, and user logins are immutably timestamped and logged—meeting core ALCOA+ (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) principles for GxP data integrity.
