Description
The OPAL-106 Hexavalent Chromium Analysis System is a precision benchtop Raman spectrometer engineered for rapid, trace-level quantification of hexavalent chromium [Cr(VI)] in industrial wastewater, metal finishing rinse baths, groundwater remediation streams, and regulatory discharge points. Capable of detecting chromate at sub-5-ppb limits of detection in under two minutes, the system provides true ion-specific speciation—differentiating toxic Cr(VI) from non-toxic Cr(III) without requiring hazardous acid digestions, diphenylcarbazide reagents, or off-site laboratory turnaround delays.
- Ion-Specific Speciation: Directly measures the Cr6+ ion, completely eliminating false positives from trivalent chromium [Cr3+] or background transition metals.
- Trace-Level Sensitivity: Sub-5-ppb limit of detection (LOD) for strict environmental and municipal discharge compliance.
- Industrial Wastewater & EHS: Rapid compliance verification for cooling tower blowdown, electroplating effluent, and NPDES discharge permits.
- Metal Finishing & Plating: Process bath and rinse tank monitoring for aerospace and automotive chrome conversion coatings.
- Remediation & Spill Containment: Real-time assessment of reduction/precipitation treatment units and immediate hazardous waste classification.
- OPAL Benchtop Spectrometer: Solid-state Raman optical measurement unit with enclosed sample measurement port.
- Universal AC Power Adapter: 100–240 VAC, 50/60 Hz power supply with standard IEC power cord.
- USB Data Interface Cable: High-speed shielded connection to host PC or laptop.
- OndaVia Raman Controller Software: Instrument communication, automated spectrum processing, and compliance reporting license.
- Calibration Verification Standard: Reusable solid-state optical standard for routine QA/QC verification.
- Documentation: Operating manual, factory certificate of calibration, and quick-start guide.
