TOC Analysis of Pure and Ultra Pure Water

  • Low sample volume / lower cost and waste
  • 9 months UV lamp life guarantee / 50% longer life
  • Continuous measurement (every 2 seconds) / fast reaction
  • Offline measurement / grab samples can be measured
  • Up to 3 sample inlets / very efficient
  • Remote service / online service diagnosis

Overview

Designed for Total Organic Carbon monitoring online and offline

The miniTOC instrument uses the classical flow-through concept for online or offline TOC monitoring of pure and ultra pure water.

The efficient UV oxidation of organic compounds by the “direct surface” principle in combination with conductivity detection guarantees the fast monitoring of values.

Calibration and SST of the miniTOC is easy and can be done by the user.

Online operation is interrupted briefly for the system checks to be performed.

The operator simply has to connect the inlet with the calibration standard solutions and the diluting water.

The software enables the user to perform calibration and SST independently, and the programmable sequence ensures the automatic procedure and data evaluation of the test.

Verification of the TOC results according to the requirements of USP and Ph.Eur is realised by the periodic performance of system suitability tests.
