GE Analytical Instruments Sievers 900 On-Line


Sievers 900 On-Line

The Sievers 900 On-Line Total Organic Carbon (TOC) Analyzer is designed for continuous monitoring of waters from ultrapure to potable. It offers superior versatility, as well as accuracy and precision across a dynamic operating range of 0.03 parts per billion (ppb) to 50 parts per million (ppm). In addition to the continuous TOC analysis mode, discrete grab samples, as well as standards, can be introduced using the patented Sievers Integrated On-Line Sampling System (IOS System™).  
The 900 On-Line Analyzer utilizes a modular design and advanced materials for maximum reliability and uptime. Engineered for ease of use and cost-effective operation, the 900 On-Line Analyzer needs no external reagents or gas supplies and requires only a few hours of preventive maintenance per year. Calibration is typically stable for twelve months. A color touch-screen display provides an intuitive menu to quickly establish operating parameters and view historical or real-time data.

The 900 On-Line combines innovative design improvements with carefully selected materials and components to ensure maximum uptime.  
Enhanced Ease of Use  
The 900 On-Line Analyzer features unsurpassed ease of use in setup, operation, and maintenance.  
Intuitive Menu-Driven, Touch Screen Interface  
A color touch-screen display makes it easy to set up instrument parameters. Trend data is displayed in tabular or graphical form for at-a-glance monitoring in real time or over user-defined time periods.  
Low Maintenance aned Operating Costs  
No external reagent or gas supplies are required, saving valuable lab space, time, and money. The Analyzer uses self-contained Sievers internal reagent packs that can be installed in minutes to achieve three to six months of uninterrupted service, depending on the application. The 900 Series Analyzers require a few hours per year of preventive maintenance. A new modular design facilitates speedy consumables replacement and prevemnive maintenance.  
Advanced Productivity and Efficiency  
Automated operations, such as calibration, verification, and data analysis reports, combine with a four-minute analysis time for the most productive TOC analyzer available. Automatic reagent adjustment eliminates the time-consuming process of manually adjusting reagent flow rates, enabling analysis to run unattended without user intervention or data interpretation.  
Extended Calibration  
The 900 On-Line Analyzer offers 12-month calibration stability, unlike competing analyzers that require weekly or even daily calibration. By following the on-screen prompts, users can select from a variety of single- and multi-point calibration procedures.  
Applications Versatility  
The 900 On-Line Analyzer has a detection limit of 0.03 ppb, allowing it to perform even in the most demanding ultrapure water applications. For higher TOC concentrations up to 50 ppm, precision and accuracy are unequalled.  
Online and Grab Sampling  
The patented Sievers Integrated On-Line Sampling System (IOS System™) allows the easy introduction of external standards and samples. This unique feature allows users to introduce calibration, validation, and system suitability standards directly without removing the instrument from the continuous sample source or changing the sample inlet configuration. It even accommodates grab samples for spot checks of TOC samples from other points in the water system.  
Expanded Data Access  
The 900 On-Line TOC Analyzer features a USB port that allows data transfers from the Analyzer to a USB flash memory drive without interrupting analysis. Data files can be opened directly in Microsoft Excel. Standard serial and parallel ports are also provided. To see a list of USB drives that are compatible with the 900 Series, click here
