Calibration, Verification & Suitability Testing of Milli-Q® Water Purification Systems

Ensure the Integrity of Your Water Purification System

Your water purification system contains critical meters, sensors and monitors which must be routinely inspected and serviced to prevent damage and to guarantee your water meets manufacturer’s specifications. In addition, periodic calibration and verification are vital for quality assurance and to guarantee the reliability of your data.

Milli-Q® Services: Specialists in Compliance and Laboratory Accreditation

As more and more regulatory guidelines require laboratories to certify the quality of their analyses, Milli-Q® Services has developed a complete accreditation solution to meet your most stringent requirements and to help fulfill GxP (e.g. GLP and cGMP) demands. We offer Calibration, Verification and Suitability Testing services for all the meters, sensors and monitors on our water purification systems. You can trust in our 20 years of experience and partnerships with regulated laboratories.

Milli-Q® Services will give you full confidence in your measuring systems:

  • Eliminate the risk of deviation over time
  • Ensure the integrity of your work
  • Strengthen your quality assurance status

Understand the Differences Between Calibration, Verification and Suitability Testing

We know it’s not always easy to determine if a verification procedure, a calibration procedure, or USP suitability test is the right solution for you. It depends on the impact of water on your applications, and on the type of accreditation or quality management system that you must follow. Our local experts in purified water regulations will help you make the most appropriate and suitable choice.

  • Calibration: Ensures and adjusts measurement accuracy against traceable reference standards. The entire measurement chain is calibrated. Our calibration service includes a calibration certificate, critical for labs complying with quality standards (e.g., cGMP, GLP).
  • Verification: Verifies and documents the accuracy of your system's meters against externally calibrated reference meters.
  • Suitability testing: Ensures water quality measurement devices comply with US pharmacopeia (USP) requirements specified in chapter <645> for conductivity/resistivity* and chapter <643> for TOC.

* For conductivity, resolution ± 0.1 μS/cm on the lowest range, cell constant ± 2%.
Less than 500 ppb detection limits check.
