MilliporeSigma™ Milli-Q™ Reference A+ System

Provides an indication if the TOC (total oxidizable carbon) value of the product water is less than the 5ppb Milli-Q Reference specification limit.

Supplier:  MilliporeSigma™ Z00QSVCUS

Catalog No. Z00QSVCUS

Description

Ideal for organic-contamination–sensitive applications like HPLC.

Adds to the Milli-Q Reference system

• Provides same specifications, plus the additional analytical precision of TOC value
• See system specifications for details

• On-line TOC monitoring detects any significant organic contamination increase in product water
• Monitoring system correlates accurately with the Millipore A10™ monitor low TOC monitoring range (1 to 10ppb); indicates increase above that range
• Integrated 185/254nm UV lamp oxidizes neutral organics into charged molecules
• Facilitates removal by mixed-bed ion-exchange resin in polishing cartridge
• TOC indicator also measures TOC based on resistivity difference upstream and downstream of UV lamp
• Proprietary “TOC Curve Check” phase adjust TOC analysis nightly to the organic mix in feedwater; also takes account of UV-variation due to deposits on quartz sleeve surrounding lamp

TOC indicator differs from TOC Monitor A10

• Indicator monitoring frequency is once per second v. A10 TOC Monitor
• Accurate detection range is 1 to 30ppb v. A10 TOC Monitor
• Monitor A10 is calibrated to reference solutions; TOC indicator is not
• A10 has Certificate of Calibration; TOC indicator does not
• Indicator has TOC Curve Check feature; not required for A10
• Suitability test as required by USP: indicator, NO; monitor, YES
