Sievers M9 Portable TOC Analyzer

Greater versatility of sampling modes and applications

The lightweight, compact design of the Sievers M9 Portable Analyzer gives you the option for TOC analysis at various locations- at-line, online, or in the lab. It offers the same accuracy and compliance as the lab model, but it can be installed online for continuous measurement or carried to any location in the water system for troubleshooting. The M9 Portable has options for simultaneous Stage 1 conductivity testing and for four-second analysis with Turbo mode for fast response applications. For the pharmaceutical industry, Sievers Validation Support Packages (VSPs) help you navigate the M9 validation process and enable a more efficient instrument implementation. The new Sievers VSP for software is written specifically to address Data Integrity and 21 CFR Part 11 by validating Sievers DataPro2 software. 

Explore the flexibility and efficiency you can gain with the M9 Portable

The Sievers M9 Portable is engineered for ease-of-use and cost-effective operation across various applications and sampling methods. Using the time-tested Sievers Membrane Conductometric technology, it supports compliance with pharmacopeia water testing or can be used for at-line cleaning validation and online applications.  

Sievers M9 Analyzers meet or exceed the most common pharmaceutical regulatory requirements for TOC analysis and data integrity.
