GE Analytical Instruments

GE Analytical Instruments (formerly Ionics Instruments) is the world's leading manufacturer of brand of on-line, portable and laboratory instruments used to measure total organic carbon (TOC) in water. In addition, we offer advanced total carbon analyzers, sulfur and nitrogen chemiluminescence detectors.

GE Analytical Instruments is a division of GE Infrastructure, Water & Process Technologies.
 

Overview

The Sievers 500 RL On-Line Total Organic Carbon (TOC) Analyzer is a reagentless analyzer designed for continuous monitoring of organics in ultrapure water for pharmaceutical, microelectronics, and power applications. The Sievers 500 RL provides the superior analytical accuracy and performance found in all Sievers TOC Analyzers, with a 0.03 ppb limit of detection and autozero capabilities for unsurpassed low-level performance.

The 500 RL TOC Analyzer provides a range of options that can be customized to meet the specific needs of a wide variety of applications.
 

400 ES Pharma TOC Analyzer

Overview

The Sievers TOC 400ES is designed for use by the pharmaceutical industry. The 400 ES provides on-line TOC analysis specifically for compliance with USP Chapter <643> and EP Chapter 2.2.44. The 400 ES monitors both TOC and conductivity in bulk water for injection (WFI) and purified water (PW). The patented Integrated On-line Sampling system (IOS™) provides unparalleled ease in applying both system suitability and calibration standards on-line.

Employing Sievers' proven membrane/conductometric-measuring technology, elimination of costly TOC false positives is assured with the 400 ES

Certified Reference Materials

Overview

Sievers® Certified Reference Materials (Sievers Standards) represent a comprehensive offering of ready-to-use TOC and conductivity standards for calibration, linearity and USP system suitability applications.
 

Sulfur Chemiluminescence Detection

Overview

In foods, flavors and beverages, for example, sulfur compounds contribute both positive and negative characteristics, and these characteristics are concentration dependent.

Sulfur chemiluminescence detection technology allows its users to not only measure total sulfur, but individual sulfur species as well, which is frequently more important, and certainly more informative than total sulfur measurements alone.

GE Analytical Instruments manufactures the Sievers Model 355 SCD to help fulfill sulfur measurement needs in production and research.
 

Nitrogen Chemiluminescence Detection

Overview

The Sievers® 255 Nitrogen Chemiluminescence Detector (NCD) builds on GE Analytical Instruments expertise in chemiluminescence detection technology.

This is accomplished by using a stainless steel burner to achieve high temperature combustion of nitrogen containing compounds to form nitric oxide (NO). A photomultiplier tube detects the light produced by the subsequent chemiluminescent reaction of NO with ozone. Because of the specificity of the reaction, complex sample matrices can be analyzed with little or no interference.
