Overview
The Anton Paar OxyQC Wide Range is a high-performance, portable optical dissolved oxygen (DO) meter engineered for precise, rapid, and reliable measurement of dissolved molecular oxygen across an exceptionally broad concentration range—from sub-ppb trace levels (0.015 ppm) up to supersaturated conditions (45 ppm). Unlike electrochemical sensors subject to membrane fouling, drift, or oxygen consumption during measurement, the OxyQC Wide Range employs advanced luminescence-based quenching technology (optical sensing) in accordance with ISO 5814 and ASTM D888–22. This principle relies on the dynamic quenching of a ruthenium-based luminophore by molecular oxygen, enabling non-consumptive, maintenance-free detection with inherent stability and long-term calibration integrity. Its robust design supports both laboratory benchtop use and demanding field or process environments—including hot/cold wort analysis in breweries, fermentation monitoring, wastewater treatment effluent control, and pharmaceutical water system validation—where mechanical durability, environmental resilience, and regulatory traceability are essential.
Key Features
- Optical luminescence sensing technology compliant with ISO 5814:2012 and ASTM D888–22, eliminating sensor polarization, electrolyte depletion, and flow dependence.
- Ultra-wide DO measurement range (0.015–45 ppm) with dual-resolution capability: 0.1 ppb resolution below 100 ppb and 1 ppb above—optimized for both ultra-trace monitoring and high-oxygen saturation applications.
- IP67-rated rugged housing with shock-absorbing rubber overmold, certified for immersion up to 1 m for 30 minutes and drop resistance from 1.2 m onto concrete.
- High-brightness, sunlight-readable 4.3-inch color LED touchscreen with adaptive contrast—operable under low-light cellar conditions or direct outdoor illumination.
- Integrated temperature and absolute pressure compensation using built-in Pt1000 thermistor and piezoresistive barometric sensor (0–10 bar abs), ensuring accurate saturation correction per ISO 5815–1.
- One-button operation with guided workflow; calibration requires only zero-O₂ and air-saturated water standards—no tools or disassembly needed.
- Built-in data logger with timestamped storage of 500 full datasets (DO, temp, pressure, timestamp, operator ID), supporting GLP-compliant audit trails.
Sample Compatibility & Compliance
The OxyQC Wide Range is validated for aqueous matrices including deionized water, purified water (PW/UPW), wort, beer, cider, bioreactor broth, activated sludge, and municipal effluents. It accommodates standard dip probes (PFD Plus) for static measurements and optional flow-through cells (SFD) for inline or recirculating loop applications. All firmware and calibration protocols adhere to ISO/IEC 17025 requirements for testing laboratories, while data export functionality supports FDA 21 CFR Part 11 compliance when used with Anton Paar’s certified software suite (e.g., LabX Lite). The instrument meets CE marking directives (2014/30/EU EMC, 2014/35/EU LVD) and carries ATEX/IECEx certification for Zone 2 hazardous area use when equipped with approved accessories.
Software & Data Management
Data transfer is supported via RS-232 serial or USB interface to Windows-based PCs running Anton Paar’s LabX Lite software—a lightweight, GxP-ready platform enabling automated report generation, statistical process control (SPC) charting, and electronic signature workflows. Optional RFID tag integration enables automatic probe identification and calibration history recall, reducing operator error and supporting ISO 17025 clause 6.4.2 (equipment management). Bluetooth and wireless printer modules facilitate real-time field reporting without tethering. All stored measurements include embedded metadata: ambient pressure, temperature, probe serial number, calibration date, and user-defined sample ID—ensuring full traceability for internal audits or regulatory submissions (e.g., USP , EP 2.2.43).
Applications
- Brewing & Beverage: Cold/hot wort DO profiling pre-fermentation, post-pasteurization oxygen ingress verification, and keg/can fill-line monitoring per ASBC Methods of Analysis.
- Pharmaceutical Water Systems: Monitoring purified water (PW) and water for injection (WFI) per USP and EU GMP Annex 1, especially at distribution loop endpoints and point-of-use locations.
- Biotechnology: Real-time DO tracking during upstream bioprocess development, including mammalian and microbial fermentations where oxygen limitation must be avoided.
- Environmental & Wastewater: Effluent compliance testing (e.g., EPA Method 360.1), landfill leachate monitoring, and aerobic digestion control with simultaneous temperature/pressure logging.
- Research & Academia: Kinetic studies of oxygen diffusion, corrosion inhibition assays, and aquatic toxicology requiring stable, non-invasive DO quantification.
FAQ
What calibration standards are required for the OxyQC Wide Range?
A two-point calibration is recommended: zero-oxygen solution (sodium sulfite saturated water) and air-saturated water (ASTM D888–22 reference). No span gas or external gas cylinders are needed.
Can the instrument measure dissolved oxygen in viscous or particulate-laden samples?
Yes—the optical sensor is unaffected by suspended solids, oils, or moderate viscosity. For highly turbid or abrasive media, the optional SFD flow cell provides continuous sample conditioning and probe protection.
Is the battery replaceable in the field?
The rechargeable Li-ion battery is user-serviceable with standard Torx tools; replacement kits and instructions are available directly from Anton Paar Service Centers.
How does pressure compensation affect measurement accuracy at elevation?
The integrated absolute pressure sensor automatically corrects % air saturation values based on local barometric pressure—critical for accurate reporting at altitudes >500 m or in pressurized vessels.
Does the OxyQC Wide Range support IQ/OQ documentation packages?
Yes—Anton Paar provides factory-verified Installation Qualification (IQ) and Operational Qualification (OQ) templates aligned with ISO 9001 and GAMP 5, including as-delivered performance test records and calibration certificates traceable to NIST standards.
