vario EL cube



The benchmark in elemental analysis

Using more than one hundred years experience in elemental analysis in close contact with today's users of our instruments the vario EL cube was developed for a growing and changing demand in the 21st century.

Designed as the successor of the most successful elemental analyzer, vario EL III, the vario EL cube is again the most versatile instrument in CHNS+O+Cl analysis.
Based on the "cube" platform it represents a thousand-fold proven method using latest manufacturing technology and intelligent engineering in the user interest. The established purge&trap chromatography guarantees baseline separation under all circumstances for all kinds of samples. From pharmaceutical to soil analysis, from sediment research to the analysis of food stuff – the vario EL cube just does it. 24 hours per day, 365 days per year.

The high-end solution for all applications:
  • no-compromise micro analysis of samples in the lower microgram range
  • semi-macro analysis for CHNS up to 1 g soil analysis
  • full digitalization for highest degree of automation
  • oxygen analysis on the highest level
  • chlorine analysis with ground breaking technology (patent pending)


Its version vario ISOTOPE cube serves for simultaneous CHNS/CNS stable isotope ratio analysis (IRMS)
 
vario EL cube - a class of its own.

Modes



Its versatility makes it ready for the future, whatever it will ask from you.

  • CHNS
  • CHN
  • CNS
  • CN


Optional:

  • O
  • Cl
  • TIC


Of course later upgrade of the instrument is possible at all times.

Specifications



High temperature combustion unit
quantitative sample digestion at up to 1200°C – with ten years furnace warranty (1800°C at the point of combustion when tin foil is used). This is the prerequisite for 100% recovery also with 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

Largest weighing range
from micro (<1mg) to macro (800mg soil) sample weight, depending on requirenemtns up to 20mg organic matter

Largest dynamic range of element concentrations and element ratio
up to 40 mg C abs. or 15 mg N abs. (or 100%), from ppm to 100%

Purge&trap Chromatography
Separation of gaseous components on up to three specific columns for perfect separation without overlap and automatic 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, 21 CFR part 11 functionality available. 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 (Argon possible alternatively)

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

Options



Electronic micro balance:
balance and elemental analyzer form a system. We offer micro balances and analytical balances from the leading manufacturers with our instruments.

For coupling with IRMS/Isoprime:
please refer to the vario EL cubes sister instrument, the vario ISOTOPE cube. This instrument is especially optimized for the use with IRMS instruments.

Sample feeder:
alternative carousels are available for larger samples with a volume up to 1 cm3

Upgrade kit oxygen:
for upgrading the basic unit to oxygen determination with a pyrolysis temperature of up to 1150°C. Conversion of the bound oxygen to CO and detection with the built in TCD or alternatively with IR technology.

Upgrade kit chlorine:
for upgrading the basic instrument for the determination of chlorine. Combustion of the sample at 1150°C and detection of the formed HCl with electrochemical sensors.

soliTIC:
addition for the analysis of total inorganic carbon only.

Steel combustion tubes:
for a longer lifetime of the tubes with extremely aggressive samples. For use in CHN and CN modes.

Capsule press:
for the dosing and gas tight sealing of tin capsules for liquid and sensitive samples.

vario Liquid Sampler, VLS:
The VLS automated sample feeder is used for liquid injections directly into the combustion chamber.

Manual gas/liquid injection:
for the injection of liquid or gaseous samples via a septum free injector port and a micro-syringe.

Sample former with pressing tool:
for the compaction of the wrapped samples and removal of air in soil samples.

Manual pressing tool:
for the manual compaction of the wrapped sample.

Consumables



Our kits of consumables contain all necessary parts and chemicals for the corresponding mode. Under more it contains combustion/reduction tubes, all chemicals and instrument specific wear parts. We do not compromise on quality of the used parts and chemicals – this is the prerequisite of a guaranteed long lifetime of our instruments.

Kits of consumables for approx. 4000/2000/1000 analysis

Kit with small wear parts: useful combination of the most important O-rings and fuses for the laboratory.

Of course all the consumables can also be ordered separately, please ask for our brochure!
