Sievers M9 On-Line TOC Analyzer

Continuous, accurate monitoring with broad, linear TOC range

The Sievers M9 On-Line Analyzer offers excellent low-level sensitivity for ultrapure water analysis and high-level capability for cleaning validation or other challenging water samples. It's proprietary Integrated On-Line Sampling (iOS) System enables easy introduction of external standards and samples without removing the instrument from the continuous sample source. With Sievers unique technology, the M9 On-Line is immune to false positive and false negatives that trouble non-membrane based TOC instruments.

Explore how to increase productivity with continuous monitoring

Designed for continuous monitoring of waters from ultrapure to potable, the M9 On-Line provides unparalleled accuracy, precision, and speed across a dynamic operating range of 0.03 ppb to 50 ppm. It supports compliance with pharmacopeia water testing or can be used for cleaning validation and other online applications. In Turbo mode, the M9 provides analysis every four-seconds, providing up-to-the-second results for better control. Sievers M9 Analyzers meet or exceed the most common pharmaceutical regulatory requirements for TOC analysis and data integrity.
