Fast, Versatile, Sensitive

The multi EA 5100 guarantees competitive advantage of your lab in terms of cost-effectiveness and analysis quality. Fast analysis is possible in three minutes for liquids and six minutes for solids. With a high sample throughput up to 160 liquid samples and up to 90 solid samples per day, costs are kept very low. Reduced consumption of consumables and less time spent on maintenance, minimize costs even further. C/N/S/X testing is carried out in one analysis cycle, the change between C/N/S and X determination is fully automatic, with no conversion of the instrument required. The unmatched detector diversity of sulfur, nitrogen, carbon, and chlorine opens up a wide range of applications and offers the perfect solution for every elemental analysis task. The modular principle allows for the system to be designed individually – an extension is possible at any time should your requirements change. The HiPerSens detection provides for a broad linear measuring range and lowest limits of detection.

Flexible automation possibilities for a high sample throughput reduce the costs per analysis considerably. A wide range of accessories is offered to boost analysis throughput. Available accessories include an automatic boat drive (ABD) with cooled sample port for the automatic introduction of liquid and solid samples. It´s integrated flame sensor guarantees matrix-optimized, quantitative combustion and prevents soot formation, thereby solving a problem common to other conventional instruments. With this technology, samples can be analyzed quickly and reliably, even if their characteristics are unknown. A multi matrix sampler (MMS) is available for automatic introduction of up to 112 liquids or 35 solids, an autoinjector for safe semi-automated injection of liquids up to 100 μl, ideal for small sample series. For LPG and gas analysis, three different matrix-optimized modules are available. You can choose between the GSS module, a gas sampling system for introduction of unpressurized or pressurized gas samples, the LPG 2.0 module for direct dosing of pressurized liquefied gases, and the GSS/LPG combi module for dosing of liquefied and pressurized gases with separate sample branches to prevent cross-contamination. With its broad application spectrum and smart features, the multi EA 5100 is ideal for industrial control labs, contract labs and state authorities in the oil and gas, petrochemical and chemical industries. Applications include process control, material testing, and waste management. Features such as flame sensor technology for matrix-optimized sample digestion – including most difficult matrices such as oils, VGO, polymers and liquefied gases – and the integrated method library are indispensable for easy routine analysis.

"Each sample is fully combusted and residue-free. That is the best foundation for reliable measurement results. We also save a lot of time in method development since, thanks to the flame sensor, each sample can be oxidized quickly and easily in a variety of quantities without precise knowledge of its combustion characteristics. We are also well prepared for the future when it comes to meeting even higher quality requirements for our products."

Technologies Making Lab Life Easier

Double Furnace Technology

The double furnace technology allows to benefit from the advantages of the vertical and horizontal digestion in one system. The easy-to-use tilting mechanism enables the system to be optimally adapted to your sample. For rapid and precise determination of liquids and gases, particularly in the trace range, the use of vertical systems has become standard. With the increase in complexity, volatility and viscosity of the samples, however, it is necessary to use the horizontal mode. The multi EA 5100 gives you unlimited application versatility, matrix optimized combustion, minimal maintenance effort, and best results for all sample types.

HiPerSens Detection

With one wide adjustment-free operation range the detectors are suitable for all concentrations. The HiPerSens detection combines highest sensitivity in ultra-trace analysis with a wide linearity up to the upper end of operation range. Thus high and low element contents can be processed together in the same sequence, only one method is required. Samples with high concentrations can be analyzed directly without dilution.

Flame Sensor

Flame Sensor technology for automatic process optimization provides the fastest possible analysis for all samples in horizontal mode. Only one method is required for all matrices of the same state of aggregation! It ensures maximum operational safety and soot-free combustion for even high sample quantities. This generates reliable measurement results with less replicates.


The Auto-Protection effectively prevents the system against damages caused by particles, aerosols and liquids. It features effective cleaning and drying of the reaction gases and monitoring and protection functions for highest analysis safety and minimum maintenance effort.
