- Model UPW - Sievers Boron Analyzer


Continuous, online monitoring of boron with Sievers UPW Boron Analyzer. The Sievers Boron Analyzers enable continuous, unattended online monitoring of ultra-low levels of boron in deionized ultrapure water applications. It's able to run 10 samples per hour and has a limit of detection (LOD) of 15 ppt boron. The Sievers Boron Analyzer is designed to meet the needs of facility managers, DI water engineers, and fab process engineers.

Easy to operate and maintain

The Sievers Boron Analyzer predicts mixed-bed exhaustion, optimizes EDI performance and controls polishing loop boron levels. The boron analyzer detects an increase in boron prior to silica release, making it useful to prevent the leakage of silica into your ultrapure water. The Sievers Boron Analyzer can significantly reduce operating expenses and maintain quality in UPW systems.
