Palintest Kemio Multi Portable Multi-Parameter Water Quality Analyzer

Overview

The Palintest Kemio Multi is a next-generation portable multi-parameter water quality analyzer engineered for high-precision, field-deployable quantification of both disinfectants and priority heavy metals in drinking water, wastewater, recreational water, and process streams. Unlike conventional colorimetric or photometric platforms, the Kemio Multi employs patented electrochemical sensor technology—specifically anodic stripping voltammetry (ASV) for metals and amperometric detection for oxidants—to deliver laboratory-grade accuracy without reliance on optical path integrity. This eliminates interference from sample turbidity, color, suspended solids, or ambient light—critical advantages in raw water, distribution system, or industrial effluent monitoring where traditional methods fail. As the unified evolution of the Kemio Disinfection and Kemio HM platforms, it integrates dual analytical workflows into a single ruggedized instrument, enabling sequential or parallel measurement of up to 12 regulated parameters within minutes per sample, all traceable to US EPA-approved methods.

Key Features

• Patented disposable electrochemical sensors with embedded microchip calibration—no manual reagent preparation, no glassware, no hazardous chemical handling.
• IP67-rated enclosure ensures operational reliability in wet, dusty, or outdoor environments; fully submersible up to 1 meter for 30 minutes.
• Touchscreen LCD interface with multilingual support (English, French, Spanish, Simplified Chinese) and integrated QR code scanning for rapid sample ID and method selection.
• Dual-mode detection architecture: ASV for trace metals (Pb, Cd, Cu, As species) at sub-ppb sensitivity; amperometric detection for oxidants (free/total chlorine, ClO₂, chlorite, H₂O₂, peracetic acid, bromine) across wide dynamic ranges.
• OEM-restricted 2300 mAh NiMH battery system ensures consistent voltage delivery and metrological stability—third-party batteries are electronically disabled to preserve measurement integrity.
• Real-time temperature compensation (5–40°C for oxidants; 5–35°C for metals) and automatic electrode cleaning cycles enhance repeatability across variable field conditions.

Sample Compatibility & Compliance

The Kemio Multi is validated for direct analysis of unfiltered, untreated, or minimally clarified aqueous matrices—including groundwater, surface water, chlorinated distribution systems, cooling towers, swimming pools, and industrial rinse waters. Its sensor design tolerates total suspended solids (TSS) up to 100 mg/L and true color up to 500 Pt-Co units without signal attenuation. All detection methods comply with US EPA Standard Methods (e.g., EPA Method 3113B for metals, EPA Method 334.0 for chlorine species) and are referenced in ISO 8694:2022 (water quality — determination of heavy metals by ASV) and EN ISO 15586:2003. Data output conforms to 21 CFR Part 11 requirements when used with Palintest’s certified software suite, supporting electronic signatures, audit trails, and secure user access controls for regulated laboratories.

Software & Data Management

Each measurement generates a timestamped record containing analyte concentration, sensor lot ID, calibration status, environmental temperature, operator ID, and GPS coordinates (when enabled via paired mobile device). All 10,000 stored results are exportable as CSV or PDF reports compliant with ISO/IEC 17025 documentation standards. The optional Kemio Connect desktop application enables batch report generation, trend analysis, LIMS integration via HL7 or ASTM E1384 interfaces, and automated method validation logs. Raw voltammograms and current-time curves are retained for technical review—essential for method troubleshooting and regulatory inspection readiness.

Applications

• Drinking water utilities: Rapid verification of residual disinfectant levels and compliance screening for Pb/Cd/As at point-of-entry and point-of-use locations.
• Environmental agencies: Field-based assessment of contaminated sites, landfill leachate, and surface runoff under EPA Region-specific monitoring protocols.
• Food & beverage production: Monitoring sanitizer concentrations in CIP systems and detecting metal leaching from stainless-steel piping or heat exchangers.
• Pharmaceutical water systems: Routine testing of purified water (PW) and water-for-injection (WFI) against USP and / elemental impurity limits.
• Public health departments: Emergency response deployment for post-flood or post-disaster water safety assessments, including speciated arsenic differentiation critical for risk characterization.

FAQ

Does the Kemio Multi require daily calibration?
No—each disposable sensor contains factory-applied calibration data encoded in its RFID chip. A one-point verification check is recommended before each analytical session using a certified standard solution.
Can the same sensor be reused for multiple measurements?
No—sensors are single-use, pre-calibrated, and auto-identified by the instrument. Reuse compromises accuracy and violates EPA method validity requirements.
Is method validation documentation available for regulatory submissions?
Yes—Palintest provides full method validation packages (including precision, accuracy, LOD/LOQ, robustness, and interference studies) aligned with ISO/IEC 17025 and FDA guidance for field-deployable instrumentation.
How is data integrity maintained during USB transfer or cloud sync?
All exported files include SHA-256 hash signatures and digital certificates. The Kemio Connect software enforces write-once-read-many (WORM) archival policies to prevent post-acquisition modification.
What maintenance is required beyond sensor replacement?
Only periodic cleaning of the electrode contact surfaces with deionized water and lint-free wipes; no consumables, optics alignment, or firmware updates required during normal operation.
