Palintest Kemio Disinfection Platform

Overview

The Palintest Kemio Disinfection Platform is a field-deployable, electrochemical sensor-based analyzer engineered for rapid, reliable quantification of critical disinfectants in water treatment, food & beverage processing, healthcare facility sanitation, and municipal distribution systems. Unlike optical or colorimetric methods—whose accuracy degrades in turbid, colored, or particulate-laden samples—the Kemio platform employs single-use, chip-integrated electrochemical sensors that operate independently of sample optical properties. Each sensor contains a proprietary working electrode architecture and embedded calibration data, enabling direct amperometric or potentiometric detection of target analytes without reagent addition, sample pretreatment, or manual dilution. This design eliminates interferences from suspended solids, humic substances, iron/manganese ions, and high UV-absorbing organics—common sources of error in spectrophotometric chlorine assays. The system is validated against reference methods per ISO 7888 (free and total chlorine) and ISO 8208 (chlorine dioxide), delivering measurement repeatability ≤±3% RSD across its full dynamic range.

Key Features

• Interference-Resistant Electrochemistry: Patented disposable sensor cartridges with integrated microelectronics eliminate dependence on sample clarity, color, or turbidity—no filtration or centrifugation required.
• Multi-Analyte Flexibility: One instrument supports six disinfectant chemistries: free chlorine (low/high range), total chlorine (low/high range), chlorine dioxide/chlorite, and three peracetic acid variants (standard, low-range, high-temperature).
• Regulatory-Ready Operation: On-board audit trail logs operator ID, timestamp, sensor lot number, calibration status, and raw signal output—fully traceable for GLP/GMP and FDA 21 CFR Part 11-compliant environments when paired with Kemio Connect software.
• Rugged Field Deployment: IP67-rated enclosure withstands immersion up to 1 m for 30 minutes; operational in ambient temperatures from 0 °C to 50 °C; no glass components or hazardous reagents.
• Intuitive Workflow: Icon-driven touchscreen interface guides users through zeroing, calibration, and measurement in under 90 seconds—no formal training required.

Sample Compatibility & Compliance

The Kemio platform accepts raw, filtered, or clarified water samples—including wastewater effluent, cooling tower water, process rinse water, swimming pool water, and pharmaceutical-grade purified water—without preconditioning. Its electrochemical architecture ensures stable response across pH 4–9 and conductivity up to 20 mS/cm. Sensor cartridges are manufactured under ISO 13485-certified quality systems and individually serialized for full traceability. Method validation reports confirm alignment with EPA Method 334.0 (chlorine), ASTM D1253-20 (residual chlorine), and EN ISO 25235:2022 (chlorine dioxide). All sensors carry CE marking and comply with RoHS and REACH directives.

Software & Data Management

Kemio Connect desktop software enables secure export of full datasets—including sensor metadata, raw current/voltage traces, QC flags, and user annotations—to CSV, PDF, or LIMS-ready XML formats. The software enforces electronic signature workflows, automatic backup to network drives, and configurable report templates aligned with ISO/IEC 17025 laboratory documentation requirements. Audit log entries are immutable and time-stamped by an internal real-time clock synchronized via USB. Data encryption follows AES-128 standards during local storage and transfer. Firmware updates are delivered via signed packages to prevent unauthorized modification.

Applications

• Municipal drinking water plants: verification of chlorine residual at entry points, storage tanks, and distribution endpoints.
• Food processing facilities: monitoring PAA concentration in CIP rinse cycles and surface sanitation lines.
• Hospital central sterile supply departments: validating chlorine dioxide efficacy in instrument sterilization tunnels.
• Pharmaceutical water systems: non-invasive, non-contaminating disinfectant verification in PW and WFI loops.
• Swimming pool & spa management: real-time adjustment of dosing systems based on accurate free/total chlorine differentiation.

FAQ

Does the Kemio platform require daily calibration?
No. Each disposable sensor includes factory-applied calibration coefficients stored in its onboard memory. A one-point verification using a certified standard is recommended before each batch of analyses—but full recalibration is not required unless sensor performance drift exceeds ±5% of expected signal.
Can the same sensor be reused across multiple samples?
No. All Kemio sensors are single-use, pre-calibrated consumables designed to ensure analytical integrity and eliminate cross-contamination risk. Reuse voids measurement validity and violates ISO 17025 traceability requirements.
Is the instrument suitable for use in explosive atmospheres?
The Kemio Disinfection Platform is not ATEX- or IECEx-certified. It must not be operated in classified hazardous zones (e.g., Zone 0/1 or Class I Div 1).
How is sensor lot traceability maintained?
Each sensor cartridge bears a unique 2D barcode scanned automatically during insertion. This links every result to the manufacturing lot, expiration date, and individual sensor calibration certificate accessible via Kemio Connect.
What battery life can be expected under typical field use?
With continuous operation (screen on, active measurements), the 2300 mAh NiMH battery supports ≥8 hours of runtime. In standby mode, it retains charge for up to 30 days.
