Market-leading accuracy and precision in EA-IRMS analysis combined with outstanding flexibility and superior ease of use – a matter of fact with vario ISOTOPE cube. The instrument can determine samples with even the most challenging C/N and C/S elemental ratios of up to 7000:1 and 5000:1, respectively.

Functional Principle

The vario ISOTOPE cube uses advanced purge and trap technology.

• Combustion Tube
• Furnace
• Reduction Tube
• Gas Separation
• Detection
• Isotope Ratio Detector

The large dynamic range of the vario ISOTOPE cube allows measurement of samples in the low microgram as well as in the two-digit milligram range. The possible applications range from testing pure organic material (e.g., charcoal) to sediments with only trace amounts of organic material. Together with its outstanding precision, the vario ISOTOPE cube is a versatile and reliable solution for a wide range of sample types.

Operating Comfort

The vario ISOTOPE cube is optimized to significantly simplify daily routine operation. Clearly arranged, easily accessible system components as well as a furnace that slides out minimize maintenance efforts. The tool-free clamp connection system ensures a reliably leak-tight instrument at any time. Thus customers can enjoy smooth analyses and confidence in their results.

One Instrument for Multiple Tasks

Simultaneous CHNS isotope ratio analysis is available via an optional H2 conversion kit. For a convenient measurement of liquid samples, the vario ISOTOPE cube can be equipped with the vario liquid sampler (VLS) for injections directly into the combustion chamber. Hydrogen isotope ratios in water can be determined with an optional Chrome HD kit, providing far better than dual inlet precisions. All optionally available conversion kits allow upgrading the vario ISOTOPE cube at any time for special applications.

Future-proof Investment

Thanks to the outstanding robustness and longevity, all elemental analyzers include a 10-year warranty on the furnace and thermal conductivity detector (TCD) cell. With the confidence that you will receive the highest level of technical support from our experienced team, Elementar provides spare parts for a minimum of 10 years after the end of production. This results in outstanding low total cost of ownership and gives customers confidence in return of investment.

Advanced Purge and Trap (APT)

Elementar’s proprietary APT technology is a unique high-performance chromatographic technique for the determination of non-metal elements. The fractionation-free APT technology is capable of resolving e.g., C/N ratios of up to 7000:1 and C/S ratios of up to 5000:1. The distinct peak separation assures absolutely reliable and trouble-free data acquisition. The data analysis can therefore be easily automated for larger sample amounts while maintaining the highest possible data quality. Elementar’s unique APT columns are optimized to provide unmatched robustness and longevity compared to GC columns. Furthermore, they can be loaded up to 250-fold higher, resulting in outstanding sample flexibility. Thus, customers enjoy industry-leading accuracy, sensitivity, and versatility.

Reliable Results

The vario ISOTOPE cube guarantees outstanding precision and accuracy through quantitative combustion via controlled oxygen jet-injection directly into the active zone. This leads to matrix-independent results even for samples which are difficult to combust. In combination with the state-of-the-art thermal conductivity detector, the instrument provides an elemental detection limit of
