- Confirm instrument health: Routine checks identify potential hardware issues or electrode degradation before they impact your experimental data.
- Maintain data integrity: Using established SOPs provides essential documentation for quality management and internal audits.
- Support compliance: Standardized workflows help labs meet regulatory standards by providing a clear "Pass or Fail" framework for instrument performance.
EasyPlus Performance Verification for EasyPlus Titrators
SOP Guide for Accurate and Reliable Titration Results
EasyPlus performance verification is a recommended workflow designed to confirm the faultless routine operation of your titration system and secure the reliability of every result. By following these Standard Operating Procedures (SOPs), you ensure measurements remain accurate, reliable, and traceable for your quality management systems. While these guidelines are based on established best practices, users should adapt the procedures to their specific laboratory requirements and compliance needs.
Why Performance Verification Is Essential
Recommended Timing for Routine Checks
Verification should be performed at these critical intervals to maintain instrument integrity and data reliability:
- Initial setup: Conduct comprehensive checks immediately after the installation of a new titrator.
- Component changes: Execute after replacing critical parts like the burette, which directly impacts volume dispensing precision.
- Consumable updates: Verify the system whenever you change to a new batch of titrant or replace a sensor.
- Periodic maintenance: As a standard quality control measure, a full check is recommended every 6 months.
Comprehensive SOPs and Acceptance Criteria
This guide supports the Easy pH, Easy Cl, Easy Ox, Easy Pro, and Easy KFV models:
- Acid-Base (Easy pH/Pro): Standardize NaOH with KHP; the mean titer must fall between 0.975–1.025 with RSD ≤ 1.0%.
- Argentometric (Easy Cl/Pro): Focuses on NaCl and silvernitrate using the EM45-BNC silver ring sensor.
- Redox (Easy Ox/Pro): Standardizing sodium thiosulphate; using the "Cautious" control mode is recommended for better repeatability.
- Karl Fischer (Easy KFV): Covers drift stability (< 25 μg/min) and water content recovery limits of 97.5–102.5%.
- Technical Execution: Always rinse the burette twice and tap tubing to remove air bubbles before starting.
- Traceable Reporting: Configure method parameters to "Export: PDF report" and "Printout: Long" for permanent records.
