vario MICRO cube



Elemental micro analysis on the highest level

The modern "cube" platform is setting the standards for elemental analyzers. Outstanding instrument design and intelligent engineering in combination with the worldwide longest experience in the development of elemental micro-analyzers lead to unmatched precision of your analysis.
Less than 1 mg pharmaceuticals can be analyzed just as precise as 800 mg soil samples. Volatile gasoline or temperature-proof silicon carbide can be analyzed just like coal, foodstuff or sewage sludge - without restriction of the elements, simultaneously for CHNS or for the combinations CNS, CHN, CN, O and Cl.
Universality and analytic performance of the vario Micro cube are also the basis for applications with isotope ratio mass spectrometry (IRMS, Isoprime).

Modes


CHNS; CHN, CNS, CN: all available from the basic unit.Optional detection of oxygen (with TCD or IR) and chlorine

 

Specifications



High temperature combustion
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 7 mg C abs. or 2 mg N abs. (or 100%), from ppm to 100%

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

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.

Upgrade kit for coupling with IRMS/Isoprime:
the vario Micro cube offers special advantages for the IRMS analysis.
Please contact us directly.

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.

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!
