  • membraPure – TOC Analyzers – miniTOC

    Online TOC control for pure water systems using highly efficient “direct surface” UV oxidation with online conductivity measurement.

    The miniTOC instrument uses the classic flow-through concept for online TOC control. The efficient UV oxidation of organic compounds by the “direct surface” principle in combination with conductivity detection guarantees the high precision of the measured values.

    The automated functions of SST and calibration facilitate a high standard of safety and minimised operating costs in controlling the water. The system is controlled on the basis of Windows 7 embedded software and through a TFT touchscreen. All data are encrypted and stored in a specific file for each day. The user has no opportunity to manipulate the raw data.

    This is an easy to use system which brings quality control to your lab at an affordable level. The miniTOC is a valuable accessory for all ultrapure water systems. miniTOC can also be ordered with interval measuring, enabling up to 3 measuring points or loops to be controlled online with just one system. The interval can be configured by the user. The minitoc can be upgraded with an offline module so grab sample can be measured.

     

    Calibration

    Calibrating the miniTOC is easy and can be done by the user. Online operation is interrupted briefly for the calibration to be performed: The operator simply has to connect the inlet with the calibration standard solution and the diluting water sample. The programmable sequence of the calibration steps will then be performed automatically. The statistical evaluation of the measurements and the corresponding calibration parameters are shown on the screen (plausibility test).

    System Suitability Test (SST)

    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. The software in the miniTOC instrument enables the user to perform SST independently and ensures the automatic procedure and data evaluation of the test.

  • membraPure – TOC Analyzers – uniTOC

    The precise high definition instruments for the online and offline determination of TOC from tap water to ultrapure water.

    Two innovative instruments for TOC analysis, uniTOC online and uniTOC lab, combine high-end analytical components certified to DIN EN 1484. The graphical control with the 10” touchscreen display and the data management of the control and analysis software meet all international standards for the determination of TOC.

    The instruments are designed for monitoring process water in areas such as pharmaceutical, microelectronics or chemical applications, as well as the production of potable water or ultrapure water. With the uniTOC analysers, membraPure provides the perfect instruments to meet the demands of the existing regulations.

     

    uniTOC Instruments – Principle of Operation

    Both instruments use the UV/persulfate oxidation procedure followed by NDIR measurement. Depending on the sample matrix, the oxidation process can even be performed reagent-free. uniTOC online and uniTOC lab both guarantee high reproducibility of results as well as high sensitivity.

    Measuring times are short and the continuous self-cleaning of the reactor avoids any cross-contamination. Since the quality of the sparging gas can be low, the use of pressurised air saves money and is optionally available. The non-dispersive infrared detector (NDIR) system is absolutely selective to carbon dioxide and therefore independent of the sample matrix. These measurements are independent of conductivity and sample temperature.

    uniTOC System Calibration

    TOC determination requires calibration, which is completely automated. uniTOC lab works with multipoint calibration and autosampler with auto dilution to measure higher concentrations of TOC. The software also facilitates automated system suitability tests (SST).

    System Suitability Test (SST)

    The verification of the TOC measurements according to the requirements of USP and Ph.Eur is realised by the frequent performance of system suitability tests. The software in the uniTOC ensures the automatic procedure and data evaluation of the test.

    Monitoring Low or High TOC Concentrations

    uniTOC online is made for pure and ultrapure water monitoring in industrial and pharmaceutical applications. The measuring range is from 3-5,000ppb and optionally up to 20,000ppb. The display shows the results of online measurements of ultrapure water even at low TOC concentrations. With uniTOC lab you will be able to measure between 15 and 40,000 ppb.

    The Aquinity² P10 ultrapure water system is equipped with a reverse osmosis (RO) cell to produce deionised water directly into an integrated 10l tank.

    Aquinity² models produce ultrapure water directly from municipal or potable tap water. In the next step Type I grade water is produced with a polisher cartridge.
    The Aquinity² P10 model is ideal for laboratories with a limited daily need for ultrapure water.

  • membraPure – Water Purification Systems – Aquinity² P35/P70

    Type I water directly from tap water

    Aquinity² P35/P70 versions have an independent tank from which RO water can be tapped (e.g. for glassware cleaning). The water quality from this tank depends on the feed water quality; in general the RO holds back 98% of all ions. The tank can be installed at the side or above the system or even underneath the bench.

    Tapping of ultrapure water is done with our flexible but also lockable dispenser as incorporated in all membraPure ultrapure water systems. Built-in TOC monitoring is also available with the Aquinity² P35/P70 versions. Aquinity² P35/P70 is the perfect system for a medium-sized lab.

    • Permeate rate: 10 l/h
    • Resistivity: 18.2 MOhm x cm
    • Reservoir: 35 l or 70 l
    • Flow Rate UPW: 2 l/min
    • TOC
      • < 10 ppb (Reagent)
      • < 3 ppb (Analytical with UV)
      • < 5 ppb (LifeScience with UV and UF)
    • Endotoxins: < 0.001 EU/ml endotoxins (LifeScience)

     

    Upgrade for Trace Analysis

    Water has to be of the highest purity to detect traces of substances in analytics processes. With the upgrade option, all components are made of unfilled material. Tubing material is PTFE for minimal adhesion. Dead spaces are avoided and the recirculation pump is made of PEEK and stainless steel. The tap valve material is PVDF.

    TOC-Monitoring

    (only for Astacus² and Aquinity² P/E 35/70)

    TOC monitoring during production and intermittent measurements during non-use periods enables a continuous check of the organics in the water. The TOC value is measured between 1 and 30 ppb and can be shown on the display to monitor organic impurities.

    memTap

    Our new automatic memTap allows the volumetric controlled tapping of water with a dispenser arm. The arm can be moved horizontally and vertically. Tap volume is preset in 0.1l steps.
