vario MACRO cube

The art of elemental analysis

High precision macro sample analysis made easy

The analysis of macro samples in coal, oil or soil industry is a special technical challenge for an analytical instrument. The vario MACRO cube is an intelligent solution for this challenge. New technical developments in combination with established methods allow the simultaneous determination of CHNS of samples up to the gram range. It is the only analyzer in the world that allows this to be accomplished fully automatically in a one-step process.

The vario MACRO cube combines function and aesthetics to a ergonomically optimized and accurate elemental analyzer. It can be used for the reliable and precise analysis of:

  • Environmental samples
  • Plant material
  • Agricultural goods
  • Food and beverages
  • Proteins
  • Feedingstuffs
  • Industrial products
  • fossil fuels
  • petrochemical samples
  • residual fuels/waste and coal/coke.

The modular design enables a customized analyzer that can be adapted to tomorrow’s needs at any time. It permits minimal sample preparation thanks to sample sizes up to 1.5 g. With the purge & trap technology for full baseline separation the vario Macro cube enables the highest precision and delivers accurate results every time.
