M5310C Portable TOC Analyser


The Sievers M5310 C Portable Total Organic Carbon (TOC) Analyzer is the most versatile of the M TOC Analyzer Series, offering maximum flexibility for how and where it is used. Weighing just 9.8 kg (21.6 lbs), it's lightweight, compact design makes it a powerful troubleshooting analysis tool that can be installed online for continuous measurement or carried to any location in the water system.

The M5310 C Portable is engineered for ease of use and cost-effective operation, allowing it to be used for single grab samples, autosampler mode, or in a process stream for continuous on-line TOC measurement.

An unequalled level of efficiency and flexibility

  • 50% faster TOC analysis over legacy 5310 C Analyzers, providing readings in only two minutes
  • Automated operations (calibration, verification, and data analysis) and Autoreagent feature enable unattended operation.
  • Saved methods are now available at the instrument. 

Easy to use and cost-effective

  • Streamlined protocols
  • Intelligent diagnostics with more informative error and alert messages and fast-links for independent troubleshooting
  • The M5310 C Analyzer’s database structure allows more useful ways to arrange, search and query data.
  • There is no need for external reagents or gas supplies.
  • The M5310 C requires only a few hours of preventive maintenance per year, and calibration is stable for 12 months.  
  • It's large, color, touch-screen display provides intuitive menus.
