Objectives

The primary objective is to gather comprehensive market intelligence regarding automatic titrators suitable for salt analysis in dairy products. This request aims to evaluate available technologies, assess operational capabilities, estimate costs, and determine service requirements to inform a future formal procurement process. Participation is strictly informational and does not create a solicitation, tender, or purchase commitment.

Scope

The scope covers the supply, delivery, and installation of an automatic titrator specifically engineered for determining salt content (expressed as sodium chloride) in butter, cheese, and processed cheese products. The evaluation encompasses equipment specifications, consumable requirements, data management capabilities, installation procedures, user training, and long-term service support tailored for routine laboratory quality control testing.

Technical Requirements

• Titration Principle: Must support potentiometric or argentometric chloride titration utilizing silver nitrate.
• Endpoint Detection: Requires high sensitivity and matrix-specific optimization to accurately detect endpoints in complex dairy samples.
• Sample Compatibility: Designed for butter, cheese, and processed cheese matrices.
• Standards Alignment: Must comply with recognized dairy chloride testing standards and applicable methods for salt determination in butter.
• Calculations & Reporting: Automated processing of chloride and sodium chloride results, incorporating sample mass, blank correction, titre correction, and unit conversions.
• Data Integrity: Includes export functionality, backup capabilities, and integration options compatible with laboratory information systems.
• Consumables: Specification of glassware, electrodes, titrants, burettes, tubing, stirrers, cleaning solutions, and their expected replacement intervals.
• Installation & Training: Complete setup, comprehensive analyst training, and provision of operational documentation.
• Service Support: Defined preventive maintenance schedules, guaranteed response times, and confirmed spare parts availability.

Skills Requirements

Suppliers must demonstrate the capacity to deliver structured training programs that equip laboratory analysts with the competencies required for routine operation, method validation, data interpretation, and basic troubleshooting. Training should cover instrument calibration, sample preparation for dairy matrices, adherence to standardized testing protocols, and proper data management practices to ensure consistent quality control outcomes.

Explanation of Technical Terms

• Potentiometric Titration: An analytical technique that measures electrical potential (voltage) changes during a chemical reaction to precisely identify the titration endpoint.
• Argentometric Titration: A specific precipitation titration method that uses silver nitrate as the titrant to react with chloride ions, forming a silver chloride precipitate until the endpoint is reached.
• Blank & Titre Correction: Standard analytical adjustments used to eliminate background interference from reagents or environmental factors, ensuring highly accurate quantification of salt concentrations.
• Data Integrity Features: Software and hardware functionalities designed to maintain accurate, complete, and reliable electronic records, often required for regulatory compliance in food testing laboratories.
