    UNICUBE trace


    Matrix-independent determination of N and C at trace levels

    The UNICUBE trace measures low-level nitrogen and carbon concentrations in solids and highly viscous liquids with a detection limit of 10 mg/kg. Its speciality: nitrogen and carbon determination are carried out using the Dumas method, which involves the removal of interfering gases during reduction and subsequent detection of the target gases using a thermal conductivity detector. As such, the UNICUBE trace is able to combine the benefits of the matrix-independent Dumas method with high sensitivity.

    With UNICUBE trace, sample digestion is carried out via catalytic combustion at a temperature of 950 °C, with the nitrogen and carbon-containing components in the sample forming a mixture of different oxides and N2. The resulting gases then pass through the reduction tube, where carbon compounds are safely reduced to CO2 and nitrogen compounds to N2. After removing other combustion products like H2O and SO2, CO2 and N2 are measured by thermal conductivity detection.

    The system is designed for easy, low-maintenance operation; matrix-independent analysis allows the use of a standard ‘universal’ calibration for any sample type.

    Enviro TOC

    Enviro TOC


    TOC analysis of environmental water and wastewater at its best

    The Enviro TOC, combines the technical know-how of its predecessor, the vario TOC select, with innovative technologies:

    Designed for environmental samples
    The analysis of TOC in wastewater to assess organic contamination or to evaluate the cleaning efficiency of sewage treatment plants is an international standard procedure. Also, TOC and TNb determination are indispensable for monitoring organic pollution and nitrogen load in surface waters. The enviro TOC is tailored to the analysis of TOC, NPOC, TC, TIC, DOC, POC or TNb in these matrices. Samples are injected with a 60-position autosampler. Integrated rinsing functions minimize carryover during the analysis of particle-containing samples. In addition, the measurement of soil samples or waste is also possible without time-consuming instrument modifications. As one of the few analyzers on the market, enviro TOC offers fully automatic TOC determination in solid and liquid samples with one system.

    TOC analyzer with flexible nitrogen determination
    The enviro TOC enables simultaneous TNb determination either using the proven EC cell technology or a novel, integrated chemiluminescence detector (CLD). The innovative CLD concept provides stable conditions for NO measurement in the carrier gas. Consequently, the NO signal is linearly correlated with the TNb concentration over a large measurement range. The built-in CLD does not require additional laboratory space and delivers extremely stable values, which simplifies calibration as well as result evaluation.

    Real matrix separation with SALTTRAP
    During the combustion of salt-containing samples, salts crystallize in the combustion tube. If the crystallization occurs directly on the quartz glass or in the catalyst, their lifetime is significantly reduced. The unique SALTTRAP of the enviro TOC guarantees user-friendly maintenance intervals of the combustion tube and the catalyst even for concentrated salt solutions, thus saving running costs during operation. Depending on the nature of the salt, a slight decrease in crystallization can be achieved by reducing the combustion temperature. However, only SALTTRAP guarantees truly effective glass corrosion protection, because the salts are trapped directly at the point where they melt.

    Easy and cost-effective maintenance
    The user-friendly maintenance concept of the enviro TOC ensures the most efficient routine analysis: Our goal is that the maximum lifetime of the instrument can be reached with minimum maintenance effort. Consequently, all consumables can be easily replaced by the user. Clearly arranged, easily accessible components guarantee that most maintenance work can be carried out independently within a very short time. This saves running costs and avoids downtime of the instrument.

    Specifications:
    Analysis methods
    High-temperature catalytic carbon oxidation up to 1200 °C and CO2 detection with NDIR for TOC, NPOC, TC, TIC, POC (VOC), DOC. TNb determination simultaneously with CLD or EC cell (option).

    Innovative detectors
    Customized, integrated detectors for CO2 and NO determination. Variable sample volumes allow multipoint calibration from a single standard solution and avoid dilution errors. Extraordinary linearity over a large calibration range.

    Modular concept for liquids and solids analysis
    Automatic sample feeders for liquids and solids, alternatively cost-efficient solutions with manual sample change. Quick and easy exchangeable. Can be upgraded at any time.

    SALTTRAP
    The innovative combustion t/ube concept enables real matrix separation and offers maximum protection of the combustion tube. Designed for analyses of salt-containing samples, particles or other complicated sample matrices.

    Software with high performance and maximum flexibility

    Soli TOC Cube

    Soli TOC Cube


    The versatile instrument for temperature-dependent differentiation of carbon in solids

    The determination of TOC in solids has recently become ever more important. Not just for evaluating wastes, TOC-content measurement is also an important aspect of assessing soils.
    The new soli TOC cube offers users the option of measuring not only total organic and total inorganic carbon, but also determining the residual oxidizable carbon (ROC). In addition to the classical TOC determination by direct and subtraction acidification methods, temperature programming can also be employed, which requires neither sample preparation nor the use of acids.

    Unmatched analytical performance
    In temperature programming, a precise, adjustable temperature is required for reproducible measurements. Thus in the soli TOC cube, the temperature is measured where it matters, directly at the crucible. This eliminates all possible thermal interferences. Additionally, the use of a post-combustion catalyst ensures that even high carbon-content samples are quantitatively oxidized and achieve equally high measurement quality.

    Simplified sample preparation
    With the soli TOC cube, larger samples on the order of grams can be reliably analyzed: just weigh the solid samples in the reusable crucibles, place them on the autosampler, and start the sequence. This makes the soli TOC cube the perfect instrument for the precise analysis of inhomogeneous samples. Measurement of TOC according to DIN 15936 is also remarkably simple. The sample is acidified directly in the ceramic crucible and after drying delivered immediately to the instrument – simple, fast, and reliable.

    Reliable analysis
    The software allows for implementing predefined methods in addition to custom programming of the heating rate and hold times. Peak integration is executed automatically and can be manually checked. This ensures that even the most difficult analyses can produce precise measurement of each individual component.

    Unsurpassed flexibility
    The soli TOC cube is capable of distinguishing between the different forms of carbon by either temperature programming or a combined temperature program with gas switching. In a single program, the TOC, ROC, and TIC can all be determined. Alternatively, the classical method of acidification, drying, and TOC measurement at constant temperature is also possible.

    Measuring method:
    True temperature ramping in an oxygenated atmosphere up to 900 °C for TOC, ROC and TIC determination in solids compliant with DIN 19539. Alternative gas switching for combination of oxidizing and non-oxidizing carrier gases in one course to separate ROC and TIC. Isothermal catalytic combustion for the determination of TOC in solids compliant with EN 15936. Option for simultaneous TN determination with ECD.

    Specifications:
    Large concentration range
    From a few ppm up to 100% or 50 mg carbon and 20 mg (0–15%) nitrogen absolute.

    Easy sample preparation and handling:
    Without any special sample preparation, all kinds of solid samples are weighed into steel or ceramic sample crucibles (sample mass up to 3 g).

    Fully automatic:
    Automated and unattended operation is possible by the integrated 89 autosampler and PC-control through Windows®. Furthermore, optional 21 CFR Part 11 compliant software is available.
