ANDalyze AND1100 Portable Heavy Metal Analyzer

Overview

The ANDalyze AND1100 Portable Heavy Metal Analyzer is an EPA-recognized field-deployable instrument engineered for rapid, on-site quantification of soluble heavy metal ions in water matrices—including drinking water, surface water, groundwater, and industrial wastewater. It employs a proprietary DNAzyme (deoxyribozyme) biosensing platform: target metal ions (e.g., Pb²⁺, Cu²⁺, Hg²⁺) selectively activate sequence-specific DNAzymes immobilized on disposable sensor cartridges. This catalytic activation triggers cleavage of a fluorogenic substrate, generating a quantifiable fluorescent signal proportional to analyte concentration. The integrated benchtop-grade fluorescence photometer detects emission intensity at defined excitation/emission wavelengths and converts it into concentration values—reported in ppb or ppm—with no requirement for laboratory infrastructure, reagent preparation, or hazardous chemical handling. Designed for regulatory compliance, the AND1100 aligns with U.S. EPA Method 200.9 principles for trace metal screening and supports Tier 1 field verification under EPA’s Environmental Technology Verification (ETV) Program.

Key Features

• Field-ready operation: Full analysis completed in ≤60 seconds from sample introduction—no incubation, digestion, or calibration curves required.
• Operator-agnostic interface: Intuitive touchscreen navigation with one-touch assay initiation; video-based training modules embedded directly in firmware eliminate dependency on printed manuals.
• Multi-analyte flexibility: Single instrument platform supports interchangeable, color-coded sensor cartridges—each pre-optimized for specific metals (Pb²⁺, Cu⁺/Cu²⁺, UO₂²⁺, Hg²⁺, Zn²⁺, Cd²⁺) and validated against matrix interferences.
• Quantitative precision at sub-ppb levels: Detection limits range from 2 ppb (Pb, U, Hg) to 40 ppb (low-range Cu), with linear dynamic ranges spanning up to three orders of magnitude per cartridge.
• Traceable data governance: Timestamped, geotagged results stored internally with audit-ready metadata; exportable via USB to CSV or PDF formats compliant with GLP documentation workflows.
• Ruggedized design: IP54-rated enclosure ensures protection against dust ingress and water splashing; battery life supports >50 consecutive assays per charge.

Sample Compatibility & Compliance

The AND1100 accepts raw, unfiltered water samples (1 mL volume) across pH 4–9. Optional accessory kits address common field challenges: AND900 (sterile syringe filtration), AND901 (10× dilution protocol), AND902 (Fe³⁺ interference suppression for Fe >30 ppb), and AND903 (pH buffering). All sensor cartridges are manufactured under ISO 13485-certified quality systems and undergo lot-specific performance validation per ASTM D5173 (Standard Guide for Field Screening of Metals in Water). Results meet EPA Region 10 field screening criteria for Pb and Cd in drinking water and are referenced in EPA’s “Emerging Technologies for Lead Testing” white paper (2022). The system satisfies FDA 21 CFR Part 11 requirements for electronic records when paired with optional secure login and audit trail logging.

Software & Data Management

Firmware v3.2+ includes embedded data management tools supporting configurable report templates, batch export, and automatic firmware updates via USB-connected host PC. Raw fluorescence intensity values, calibration references, and environmental parameters (ambient temperature, battery level) are logged alongside each measurement. Exported datasets include ISO/IEC 17025-aligned uncertainty estimates derived from cartridge-specific calibration certificates. Cloud synchronization is not supported; all data remains on-device or locally transferred—ensuring full control over sensitive environmental monitoring records.

Applications

• Rapid lead service line screening in municipal distribution systems per EPA Lead and Copper Rule Revisions (LCRR).
• Pre-compliance verification of industrial effluent prior to discharge permit submission.
• Post-remediation validation at Superfund sites targeting residual U, Cd, or Hg contamination.
• Field validation of point-of-use filter performance in community water systems.
• Academic and NGO-led water quality surveys in resource-constrained regions where lab access is limited.

FAQ

Does the AND1100 require daily calibration?
No. Each sensor cartridge contains factory-applied calibration coefficients; instrument self-verifies optical path integrity before every assay.
Can the AND1100 measure total metals or only dissolved fractions?
It measures bioavailable, filterable (≤0.45 µm) ionic species only—consistent with EPA’s definition of “dissolved metals” in Method 200.9.
Are sensor cartridges reusable?
No. All cartridges are single-use, sterilized, and disposed of as non-hazardous solid waste—eliminating cross-contamination risk and cleaning validation steps.
What regulatory standards does the AND1100 support for reporting?
Results are admissible as Tier 1 screening data under EPA ETV protocols and satisfy state-level field verification requirements in CA, NY, and MI for Pb and Cu in drinking water.
Is technical support available outside the U.S.?
Yes. ANDalyze provides remote diagnostics and multilingual firmware updates globally through authorized regional distributors—no on-site service contracts required.
