miniTOC, MembraPure

miniTOC, MembraPure, Germany

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.

Technical Specifications:

Method & detection: UV-Oxidation & conductivity

Sample volume flow: ca. 14 mL/min

Total Organic Carbon (TOC)-Range: 0.5 to 1000 ppb

Related norms: USP <643>, EP 2.2.44, DIN EN 1484

miniTOC advantages

  • Low sample volume / lower cost and waste
  • 9 months UV lamp life guarantee / 50 % longer life time range than usual
  • Continuous measurement (every 2 seconds) / fast reaction
  • offline measurement / grab samples can be measured
  • up to 3 sample inlets / very efficient
  • remote service / Instrument can be connected to internet to get service diagnosis)

Calibration & System Suitability Test (SST)

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


intervall mode:

The miniTOC can be ordered as configuration with 4 inputs (miniTOC pro). With an additional software upgrade option the user can measure up to 3 loops sequentially.

Offline Version & autosampler

An offline configuration is available for the miniTOC. By using the offline mode of the miniTOC pro the system is also upgradable with an autosampler with 15 positions for 100 mL vials.

check of sample flow

Initiates alarm in case of inlet flow is zero

heat exchanger

If the medium temperature is higher than 50 °C a heat exchanger is required.

pressure regulator

If the medium pressure is higher than 1 bar a pressure transducer is required.
