OH, H, O: all available from the basic unit.
Optional CNS, CN, N, S mode, optional H with HDChrome
High temperature pyrolysis
quantitative sample pyrolysis at up to 1,500 °C . This is the prerequisite for 100% recovery also for samples difficult to pyrolyze. Equipped with one silicon carbide heater element and a standard reduction oven, it allows full flexibility without any compromise.
Low instrument background
Due to the novel reactor design with fully separated gas flow a very low background signal has been achieved.
Largest dynamic range of element concentrations and element ratio
Sample weight between 0.02 mg and 1 g with up to 6 mg O abs., 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. A peak separation to the baseline, e.g. for CO2 and N2, can be reached even with a concentration ratio of 5000:1.
Specifically equipped with novel backflush technology to guarantee full nitrogen-carbon monoxide separation for highly accurate analysis of oxygen.
with a standard PC for perfect results also for unknown or heavily variable sample matrices with integrated sample feeder for 120 samples. 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 pyrolysis 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
Few 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.
Upgrade kit for CNS combustion analysis:
For the combustion analysis for CNS isotope ratio measurements. The separation of the combustion gases is performed using the established purge and trap technology. From the combustion gas the components CO2 and SO2 are adsorbed at two specific columns, whereas N2 directly enters the TCD in combustion mode.
ChromeHD kit for individual dD analysis of water:
For the application of HD ratios in water in a quartz tube using patented ChromeHD technology for the reduction to H2. Providing dual inlet like precisions.
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 pyrolysis/combustion chamber.
alternative 80 position carousels are available for larger weight 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, such as 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
Everything you need for carefree sample analyses.
Kits 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.
Here are a selection of our customers around the world that are using the vario PYRO cube in their research
Dr Federica Tamburini is a researcher in the group of Plant Nutrition at the Institute of Agricultural Sciences at ETH Zurich (Switzerland), where she manages the stable isotope facility. The group uses the vario PYRO cube elemental analyzer for investigating the phosphorous cycle in soil/plant environments by analysing 18O in phosphate materials. 18O analysis of phosphate has previously been considered a demanding analysis but by using the vario PYRO cube, Dr Tamburini and colleagues now measure these sample types routinely.
Dr Peter Wynn is a Senior Lecturer at Lancaster University, and is based within the Lancaster Environment Centre (LEC). He is a Stable Isotope Geochemist researching in the fields of palaeoclimate reconstruction and glaciology. The department's particular specialty is analyzing sulfur isotopes and undertaking high temperature oxygen pyrolysis and the team has established techniques to extract sulfur isotopic signals from palaeo records, including speleothems, tree rings and carbonate rocks. Using the vario PYRO cube elemental analyzer, the group are able to determine the 34S and the 18O isotopic ratio of sulfate materials to help answer questions about deep geology and pollution migration.
