MilliporeSigma™ Milli-Q™ Reference A+ System

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
