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 (<1 mg) to macro (800 mg soil) sample weight, depending on requirenemtns up to 20 mg 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%
Separation of gaseous components on up to three specific columns for perfect separation without overlap and automatic optimization of the analysis time
stable over months and matrix independent
with a standard PC for perfect results also for unknown or heavily variable sample matrices with integrated standard sample feeder for 80 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
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.
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 sulfur
For upgrading the basic instrument for highly precise sulfur determination in the trace concentration range.
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.
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.
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.
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 analysis
