Vario EL cube

Elemental Analyzer vario EL cube for simultaneous CHNS analysis with options for O and Cl analysis

Innovative universal instrument for the determination of the element contents in organic and most inorganic solids and liquids (capsule sealing press as accessory).
Optimized for the measurement of samples in the weighing range of 0.03 mg up to approx. 50 mg organic substance, but also applicable e.g. for 1 g soil.

VarioEL-Cube

  • Automatic sample carousel for 120 samples, in single and permanent operation; reloadable at any time during operation (80 position carousel for larger samples optional).
  • Blank free sample injection by means of the ball-valve with He-purging based on a Heraeus patent.
  • Time controlled combustion in pure oxygen with a permanent temperature of max. 1200°C. This high furnace temperature is a prerequisite for 100% recovery in S- and O-analysis.
  • The separation of the combustion gases is performed using the established purge&trap chromatography method. From the combustion gas the components CO2, H2O and SO2 are adsorbed at three specific columns, whereas N2 goes directly to the TCD.
  • Depending on the detector reading, the gas components are controlled and chronologically released and detected.
  • A peak separation to the baseline e.g. for CO2 and N2 can be reached even with a concentration ratio of 5000:1.
  • Detection of the measuring gases with a wide-range thermistor TCD, destruction-proof against oxygen. Almost maintenance free detector function over many years. Unproblematic analysis of fluorinated samples within a regular sample mix.
  • In connection with an electronic massflow controller directly before the detector excellent long time stability is reached.
  • Helium carrier gas as standard with full specifications, alternatively Argon can be used.
  • Modern electronics and instrument software under Windows® XP professional or Vista business for the user-friendly operation and data evaluation of the analyzer (English or German) via a connected PC.
  • Integrated user maintenance software with automatic leak test, wake-up/sleep function, direct data export into Excel® and connection to LIMS and other data networks.
  • All operation functions and checks incl. gas flows and pressures are digitally controlled and/or readout capable. Thus a remote diagnosis and operation via the internet is possible.
  • Easy to maintain and cost efficient long-term operation. High safety standard, e.g. by low voltage in the entire instrument incl. furnaces.
  • Complete set of initial outfit for installation of the analyzer including consumables for approx. 1,000 analysis.
  • Detailed electronic operating manual, fully integrated into the software.
  • 10 years furnace guarantee.
