Overview
The HACH ANDalyze Portable Heavy Metal Analyzer is an engineered field-deployable instrument designed for rapid, on-site quantification of dissolved heavy metal ions in drinking water, surface water, and industrial wastewater. It employs a proprietary DNAzyme-based biosensing platform—where sequence-specific catalytic DNA molecules selectively bind and cleave in the presence of target metal ions (e.g., Pb²⁺, Cu²⁺, Hg²⁺), triggering a fluorogenic reaction. The integrated fluorescence photometer detects emitted signal intensity at defined excitation/emission wavelengths, converting it into concentration values (ppb or ppm) via pre-calibrated response curves. Unlike conventional atomic absorption or ICP-MS methods, ANDalyze eliminates the need for acid digestion, high-voltage plasma sources, or certified laboratory infrastructure. Its measurement principle aligns with EPA Method 1631E (for mercury) and EPA Draft Method 6020B (for multi-element screening), supporting compliance-ready data acquisition under field conditions.
Key Features
- Field-validated operation: Delivers quantitative results in ≤60 seconds per sample, with no chemical reagents, hazardous waste, or external power supply required beyond internal rechargeable battery.
- DNAzyme sensor technology: High selectivity against interferents (e.g., Ca²⁺, Mg²⁺, Fe³⁺); cross-reactivity minimized through enzyme engineering and buffer optimization.
- Multi-parameter capability: Single instrument supports interchangeable sensor cartridges for Pb, Cu (low/high range), U, Hg, Zn, and Cd; future expansion planned for Cr(VI) and As(III).
- IP54-rated rugged housing: Dust- and splash-resistant enclosure suitable for outdoor deployment in ambient temperatures from 5 °C to 40 °C.
- Integrated data logging: Timestamped, geotagged results stored internally (up to 1,000 records); exportable via USB 2.0 to CSV or Excel-compatible formats.
- Self-contained calibration and diagnostics: On-device verification routines, firmware update capability via USB, and embedded instructional video library accessible without external devices.
- Regulatory alignment: CE-marked; compliant with ISO/IEC 17025 documentation requirements for field screening; supports audit trails compatible with GLP/GMP workflows when paired with Hach’s LIMS-integrated reporting software.
Sample Compatibility & Compliance
The ANDalyze system accepts untreated aqueous samples (1 mL volume) with turbidity ≤10 NTU and pH 4–9. For high-iron matrices (>30 ppb Fe), optional iron-interference suppression kit (AND902) is recommended. All sensor cartridges are single-use, factory-calibrated, and traceable to NIST-traceable reference standards. Measurement ranges meet or exceed EPA-defined action levels for regulated metals: Pb (15 ppb MCL), Cd (5 ppb), Hg (2 ppb), and U (30 µg/L). Sensor shelf life is 12 months when stored at 2–8 °C; no cold chain required during transport.
Software & Data Management
Instrument firmware supports multilingual UI (English, Spanish, French, Chinese, German). Data export includes full metadata: date/time stamp, GPS coordinates (when enabled via connected smartphone), operator ID, sensor lot number, and raw fluorescence intensity. Optional Hach DataLink™ software enables batch report generation, trend visualization, and integration with enterprise environmental monitoring platforms. Firmware updates preserve historical calibration coefficients and maintain 21 CFR Part 11–compliant electronic signature functionality where configured.
Applications
- Rapid source water assessment during emergency response (e.g., post-flood lead leaching events)
- Compliance screening at municipal water distribution points and wellheads
- Industrial effluent monitoring prior to discharge permit verification
- Environmental site assessments (ESAs) and brownfield investigations
- Educational field labs requiring safe, non-toxic analytical methods
- Community-led water quality surveillance programs in resource-limited settings
FAQ
What regulatory methods does ANDalyze validate against?
ANDalyze performance has been verified per EPA Method 1631E for mercury and meets sensitivity requirements outlined in EPA Draft Method 6020B for multi-element field screening.
Is sample filtration required before analysis?
Yes—turbid or particulate-laden samples must be filtered using the included 0.45 µm syringe filter (AND900 kit) to prevent sensor fouling and optical interference.
Can the same sensor cartridge be reused?
No—each sensor is single-use and calibrated for one analysis only. Reuse compromises accuracy and violates ISO 17025 traceability requirements.
How is method validation documented?
Each sensor lot ships with a Certificate of Analysis including limit of detection (LOD), linearity (R² ≥0.995), and inter-lot precision (RSD ≤8% at mid-range concentrations).
Does ANDalyze require annual recalibration by a service technician?
No—calibration is embedded in each disposable sensor; instrument optical path is validated daily via built-in reference LED and dark-current compensation.
