The UNICUBE trace is optimised for nitrogen determination at trace levels.
UNICUBE trace offers quantitative sample digestion at up to 1,200 °C - with a 10-year furnace warranty - and is able to deliver complete conversion of all N components into N2. The jet injection of oxygen directly to the sample leads to the highest oxygen concentrations at the point of combustion, while minimising gas consumption.
Largest weighing range:
The weighing range encompasses micro (< 1 mg) and macro (around 1 g of soil) applications, depending on requirements, and can be used to analyse up to 20 mg of organic matter.
Largest dynamic range of element concentrations and element ratio:
UNICUBE trace supports element concentrations and ratios up to 50 mg C abs. or 10 mg N abs. (or 100%, depending on analysis mode and sample matrix), from ppm to 100%, LOD 10 ppm N and C
Offering matrix-independent stability for months at a time.
PC-based instrumentation control
Full digitalisation of the instrument allows for remote operation from a standard PC and perfect results, even when dealing with unknown or heavily variable sample matrices. The integrated standard sample feeder accommodates 120 samples, with 21 CFR part 11 functionality also available.
One simple instrument for all applications
UNICUBE trace requires no expensive special catalysts, facilitating easy ash removal from the combustion tube and offering long-lasting components to ensure a low cost of ownership.
Clean, safe and fast
Each analysis only takes a few minutes and uses helium carrier gas, with no aggressive or toxic chemicals needed.
Easy installation requirements
UNICUBE trace takes up just 48 x 55 cm of benchtop space and operates using a single power supply (230, 110 or 100 V) and two gases, providing lengthy periods of maintenance-free operation.
The elemental analyser forms a system with an electronic microbalance, which is offered alongside analytical balances from the leading manufacturers with our instruments.
Alternative carousels are available for larger samples, with a volume of up to 1 cm3.
For the dosing and airtight 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 system:
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 wrapped samples and the removal of air in soil samples.
Manual pressing tool:
For the manual compaction of the wrapped sample.
We offer all consumables required for the operation of our analysers. These include:
We do not compromise on the quality of our parts and chemicals - this is the prerequisite of the guaranteed long lifespan our instruments offer. When using original consumables from Elementar, a 10-year warranty on the high-temperature combustion furnace and thermoconductivity (TCD) cell is offered.
