Overview
The EVA Automatic Karl Fischer titrator family provides volumetric and coulometric instruments for precise, automated water content determination. Modular Swiss design supports benchtop use and scalable rack automation; integrated software and touchscreen control centralize method setup, data capture and traceability.

Key Benefits

• Efficient throughput using the Fast Forecasting Amperometric (FFA™) algorithm to optimize titrant use and reduce analysis time.
• Method flexibility: choose volumetric or coulometric workflows depending on required detection range.
• Automation-ready: compatible with InMotion KF autosamplers for unattended operation and high sample throughput.
• Traceability and compliance via LabX™ integration with audit trails and electronic signatures.

Core Features

• FFA™ control algorithm for dynamic titrant forecasting and adaptive dosing.
• dSens M143 digital polarized double‑platinum pin sensor for fast, interference‑resistant measurements.
• dDrive high‑resolution dosing on V1/V3 (up to 120,000 steps) for precise titrant delivery.
• Low burette dead volume (~54 µL) and automatic emptying to reduce carryover.

Swiss Modularity

• Modular modules (burettes, sensors, cells) snap into a plug-and-measure frame enabling rapid reconfiguration.
• Options for standalone benchtop or multi-position automated racks to match lab footprint and throughput.

Workflow Integration

• OneClick™ touchscreen simplifies operation and reduces training time.
• LabX™ connects to LIMS/ELN/MES/CDS for centralized data management and CFR-ready reporting.
• Automated transfer of sample weight and titrant parameters minimizes transcription errors; automatic sample detection and method start supported.

Regulatory Compliance & Traceability

• LabX™ provides user management, electronic signatures and audit trails for 21 CFR Part 11 and EU Annex 11 compliance.
• Data integrity aligned with ALCOA++ principles to support validation and audits.

Safety & Solvent Handling

• Closed-loop solvent exchange and spill-protected KF hybrid cells reduce exposure and bench contamination risk.
• Detachable touchscreen (2.5 m cable) enables remote operation when required.

Sustainability

• Support for ethanol‑based reagents and low‑solvent protocols to reduce hazardous solvent use and waste.
• Paperless documentation via LabX™ lowers administrative overhead and resource consumption.

Methods
Volumetric titrators cover a broad range (~100 ppm to 100% water) for routine and formulation testing. Coulometric titrators target ultra‑low levels (approx. 1 ppm – 5%) for trace analyses. Select the method according to sample matrix and detection needs.

Product Variants & Instruments

• EVA V1 — Volumetric KF: routine, fast analysis for soluble samples.
• EVA V3 — Volumetric KF: enhanced versatility for challenging matrices; supports homogenizer, external extraction and InMotion integration.
• EVA C1 — Coulometric KF: trace-level detection and quantification.
• EVA C3 — Coulometric KF: automated trace-level solution for high-throughput labs.

Accessories
Thermostatable KF vessels, burette sizes (e.g., 10 mL), homogenizer adapters (12 mm, 18 mm), terminal cables (250 cm), InMotion KF autosamplers (Six, Flex, Pro), homogenizers (IKA T25, Kinematica POLYTRON) and oven extraction units support direct, internal, external and gas‑phase extraction workflows.

Applications
Applicable industries include food & beverage, pharmaceuticals, petrochemicals, plastics & polymers, batteries & electronics and specialty chemicals. EVA systems support direct addition, internal homogenization, external extraction and oven extraction depending on sample solubility and matrix.

Services & Support
Installation and qualification (IPac/EQPac), calibration, documentation, extended service packages, global support and training offerings to help maintain continuity and compliance.
