The modern "cube" platform setting the standards for elemental analyzers - and your isotope ratio analyses will profit from it. Outstanding instrument design and intelligent engineering in combination with the worldwide longest experience in the development of elemental micro-analyzers lead to unmatched accuracy of your measurements. The vario ISOTOPE select, in conjunction with a gold-standard IRMS from Isoprime, is designed to meet the special needs of continuous flow IRMS – highest sample throughput at unrivalled performance.

Less than 1 mg pharmaceuticals can be analyzed just as precise as
300 mg soil sample. Volatile gasoline or temperature-proof silicon carbide can be analyzed just like coal, foodstuff or sewage sludge - without restriction of the elements, simultaneously for CNS. The superior temperature-programmed desorption technique guarantees highly efficient peak separation, even for samples with extreme element concentration ranges.

Equipped with a 120 position autosampler for high sample throughput and the most user-friendly operating software on the market, the vario ISOTOPE select is setting new benchmarks. Unrivalled universality and analytic performance of the vario ISOTOPE select form the basis for its success in isotope ratio analysis.
 

• Specifications

  High temperature combustion
  quantitative sample digestion at 1200 °C (up to 1800 °C at the point of combustion when tin foil is used) – with ten years furnace warranty. This is the prerequisite for 100% recovery also for samples difficult to combust. Jet injection of oxygen directly to the sample leads to highest oxygen concentrations at the point of combustion and low gas consumption.

  Large weighing range
  from <1 mg to 300 mg (soil) sample weight, depending on requirements up to 14 mg organic matter

  Largest dynamic range of element concentrations and element ratio
  up to 7 mg C abs. or 10 mg N abs. (or 100%, depending on analysis mode and sample matrix), from ppm to 100%

  Temperature programmed Desorption (TPD)
  Separation of gaseous components with one TPD column for perfect separation without peak overlap. Automated optimization of the analysis time.

  Multipoint calibration
  stable over months and matrix independent

  Instrument control
  with a standard PC for perfect results also for unknown or heavily variable sample matrices with integrated sample feeder for 120 samples. Possibility for remote service due to full digitalization of the instrument electronics

  One basic instrument for all applications
  No expensive special catalysts, easy ash removal from the combustion tube and long lifetime of all components are the basis for a low cost of ownership

  Clean, safe, fast
  The analysis only takes a few minutes, no aggressive or toxic chemicals are used, helium carrier gas

  Easy installation requirements
  48 x 55 cm benchtop space, 1 power supply (230, 110, 100 V), and two gases are sufficient for maintenance free long time operation
