Sievers M5310 C Portable TOC Analyzer

Portable, lightweight analyzer designed to meet regulations and optimize processes

The Sievers M5310 C Portable Total Organic Carbon (TOC) Analyzer is the most versatile of the M5310 C series. Its light weight and compact design makes it a powerful troubleshooting analysis tool that can be used for single grab samples, in autosampler mode, or in a process stream for continuous on-line TOC measurement. Offering an operating range of 4 ppb to 50 ppm, this analyzer is engineered to support regulatory compliance and processes optimization goals.

Sievers M5310 C Portable features two operating modes - continuous or grab sample. Equipped with the Integrated On-Line Sampling System (IOS System™), the M5310 C Portable allows the easy introduction of external standards and samples without removing the instrument from the continuous sample source. 

Features and Benefits

M5310 C Portable Features and Benefits

  • Provides readings in only two minutes
  • Simple and intuitive
  • Automated calibration, verification, and data analysis enable unattended operation
  • Automatically calculates percent TOC removal for influent and effluent streams or samples
  • The Autoreagent feature automatically establishes optimal flow rates for each sample
  • Pre-calibrated for simple installation
  • Minimal maintenance — typically just a few hours per year 
  • Self-contained with small footprint and internal reagent packs — no external chemicals, catalysts, or gas supplies required.
  • Easy data communications — export or collect data via USB, 4-20 mA, or Modbus TCP/IP outputs
  • IOS system allows testing of external samples and standards without removing the analyzer from the continuous water source
  • The grab-mode, alphanumeric labeling feature allows individual labeling of each grab sample for easy recall later on
