GE Analytical Instruments Sievers 500 RLe


Sievers 500 RLe

The Sievers 500 RLe On-Line TOC Analyzer represents the latest advancement in the science of ultra low-level TOC measurement in microelectronic applications. The 500 RLe replaces the Sievers Model PPT as the industry’s only on-line, reagentless TOC analyzer capable of accurately detecting problematic compounds such as urea, trimethylamine, organic acids and bases.  
The 500 RLe uses GE Analytical Instrument's membrane conductometric technology, delivering ultra low-level accuracy and reliability by eliminating false positive and false negative readings associated with other simplified TOC technologies.

Economical Designs  
The 500 RLe comes in two models to meet your needs:  
  • The 500 RLe with Standard iOS (Integrated On-Line Sampling System) utilizes the familiar Sievers sample inlet device, allowing for on-site calibration, running of standards and grab samples.  
  • The 500 RLe Base Model utilizes a simplified sample inlet block, facilitating continuous on-line operation. On-site calibration may be performed using an optional iOS accessory. The 500 RLe Base Model is cost-competitive with even the simplest TOC sensors while still providing superior analytical performance and optional on-site calibration.  
Master TOC Calibration  
The 500 RLe has a manual TOC offset adjustment, so any 500 RLe can be calibrated to a reference TOC analyzer.   
Higher Conductivity Limits  
The 500 RLe incorporates design elements from the Sievers 800 and 900 Series that enable reagentless TOC measurement in waters up to 25 ΜS/cm. Equally as important, this design enhancement means that fluctuations in UPW system conductivity or plant transients do not affect analytical performance.  
Sensitivity, Accuracy and Stability  
With microelectronic TOC limits being driven ever lower, it is critical that TOC analyzers operate accurately and reliably at sub-ppb levels. The 500 RLe achieves the lowest detection limit of any TOC analyzer on the market — 0.03 ppb — and provides the confidence that all organics are being fully recovered regardless of chemical composition. The combination of analytical robustness and stable sub-ppb performance provides confidence that critical UPW processes are protected and that even the most subtle trends can be closely monitored.
