High Performance with Low Maintenance

The multi EA 4000 convinces with its durable design. The selected resistant materials are an advantage when analyzing aggressive and saline samples that cause a high degree of wear with traditional systems. A special optics arrangement and effective gas purification provide a resilient C/S detector that guarantees for extremely low maintenance and excellent long-term stability. Maintenance effort is reduced to a minimum while the operating time of the system is at maximum. Low operating costs and an absolutely reliable analyzing and measuring technique ensure each process step is as effective and efficient as possible.

  • Use of robust and virtually wear-free ceramic combustion tubes instead of cost-intensive and quickly worn-out quartz combustion tubes
  • Minimal chemical consumption thanks to high-temperature ceramic technology (HTC) – no catalysts needed
  • No complex reduction and separation of the oxidation products (chromatographic via adsorption columns) required – due to the use of selective detectors for CO2, SO2 and HCl
  • No auxiliary gas required for carbon and sulfur analysis
  • High sample weights up to 3 g, no laborious sample homogenization required

Thanks to the variable gas flow management and the optimized wide range coulometer, chlorine analyses are possible from the low ppm up to the weight percent range. The coulometric detection system utilizes a unique patented combination electrode. The electrode is based on the latest ceramic technology and does not use internal electrolytes, membranes, or diaphragms. It is immediately ready for use and very low maintenance. The measuring cell is equipped with an automatic stirring function and a self-cleaning silver generator electrode. The integrated cooling of the coulometer cell minimizes electrolyte evaporation while in continuous operation and guarantees stable results. Compared with traditional electrolytes, the special electrolyte used has a significantly increased chloride absorption capacity. This results in long-term stability, which allows for uninterrupted routine analyses even with extremely high chloride loads and without bothersome electrolyte changes.

The challenge modern analytical systems for marco-elemental analysis face lies in reliable automation for an extensive range of samples. The multi EA 4000 offers the fully automatic determination of TOC based on the differential method. The FPG 48 solids sampler offers an enormous capacity for up to 48 sample boats to be transferred into the combustion furnace. Other accessories include modules for direct and automated determination of TIC and TOC. The multi EA 4000 with its high sample throughput is ideal for the automated analysis of carbon, sulfur, and chlorine, as well as the automated determination of total organic and inorganic carbon. By setting different waiting positions and feed speeds, samples of one and the same run each of them can be analyzed under optimal conditions. This means matrices requiring a special temperature program or gradient are processed easily and automatically together with others. An open gas lock replaces problematic sample ports that require opening and closing for sample introduction. It is completely maintenance-free, which avoids contamination and wear. A method library is included to ensure that the analysis of your sample is carried out optimally and reliably. The multi EA 4000 comes equipped with a Self Check System (SCS). The system automatically checks all relevant parameters such as flows and temperatures and guarantees trouble-free, fully automated operation with functions such as the automated gas shut-off and a low standby temperature at the end of an analysis sequence.

Easy Analysis Even for Complex Matrices

Optimum sample digestion guaranteed

Thanks to high-temperature ceramic (HTC) technology, samples can be fully decomposed up to a temperature of 1,500 °C in a stream of oxygen and without the use of catalysts. For especially complex matrices, the combustion temperature can be temporarily increased up to 1,800 °C by using additives. With these conditions, even thermally stable compounds, such as sulfates and carbides, are fully oxidized. Pyrolysis is an additional function of the multi EA 4000, useful for the analysis of solid waste among others. Pyrolysis enables to distinguish between the environmentally relevant biodegradable organic carbon (BOC) and the residual carbon (RC). Pyrolysis takes place at e.g., 850 °C in an inert gas atmosphere, the BOC is calculated from the difference between TOC and RC content. You can also use the pyrolysis option for the determination of the active carbon content. The flame sensor is an optional accessory for automated chlorine determination. It guarantees complete combustion of the sample. First, the sample is pyrolyzed within inert gas. Then the pyrolysis products are combusted in a pure oxygen stream. The control of the formed flame by the flame sensor is the key to complete combustion and elimination of soot. Automatic TOC and TIC analyses are quicker and easier than ever before! Easily determine the TOC and TIC parameters from one single sample in only one analysis step, fully automatically, quickly and in compliance with standards. Complex manual sample preparations for direct TOC determination are no longer required. Another unique feature is the fully automatic determination of TOC based on the differential method. In combination with the FPG 48 solids sampler, the automatic TIC solids module enables comfortable determination of TOC in samples such as soil, waste and many other materials.

Simultaneous determination of carbon and sulfur

Special wide range NDIR detectors allow for simultaneous determination of carbon and sulfur within a dynamic measuring range from ppm to weight percent while maintaining high linearity. The flexible measuring range allows to determine extremely different contents of sulfur and carbon in one and the same sample. The integrated VITA Flow Management System guarantees reliable NDIR signal evaluation and stable measurement results. The signal is logged regardless of fluctuations in the measuring gas flow so that the evaluation yields reliable results. At the same time, the system registers the flow of the measuring gas and compensates fluctuations by computerized standardization of the NDIR signal to a constant flow rate.

VITA Flow Management System

  • Excellent reproducibility of the results
  • Clear matrix independence
  • High long-term stability of the calibration
  • Easier calibration
  • Electronic flow control of the system

Software

multiWin

The self-explanatory multiWin software accompanies the user through all relevant menu points. multiWin is intuitively structured and thus offers the user a comprehensible and simple handling. The Self Check System - an intelligent combination of hardware components and software functions, guarantees uninterrupted and fully automatic operation of the analyzer and its accessories. It monitors and regulates all important system parameters. It immediately points out errors in the configuration of the system and detects unsuitable parameters, thus avoiding low quality results from the very beginning. The software continuously checks the system’s performance and the quality of analysis. multiWin provides free evaluation of sample data even during running measurements, the automatic selection of the optimum calculation function, the fully automatic set up of calibration curves for special applications, the possibility of individual recalculation of results, as well as the clear display of the measurement results. The implemented maintenance counter and intelligent software feature to trigger life time and performance of relevant components make maintenance more predictive, saving time and effort while preventing system failures. Data and parameters can be conveniently managed and stored, and results can be easily forwarded using automatic or manual data import or export functions, including LIMS import and export of data. For elemental analysis with multi EA 5100 and 4000 series the multiWin software includes an extensive library of more than 100 approved, ready to use and stanadard compliant and special application analysis methods. This significantly simplifies analyses according to standard regulations such as ASTM, EPA, DIN, ISO, and UOP. Preconfigured methods eliminate time-consuming method development and allow for fast, correct measurements independant of operators skills.
