Vario MACRO Cube

Simplified, accurate macro-sample analysis

The elemental analysis of macro samples, whether coal, oil, or soil, presents a technical challenge for any analyzer. With the vario MACRO cube, the elemental analysis experts at Elementar have solved this challenge in a sophisticated way.

The CNHS macro analyzer combines innovative new technical solutions with proven techniques to enable simultaneous determination of CHNS in samples up to the gram range. This makes it the world’s first analyzer to achieve this possible in a single, fully automated step.

Thanks to the ergonomic and functional design of Elementar’s cube instrument range, the modular vario MACRO cube is built to meet both current and future laboratory needs. Most importantly, this macro elemental analyzer delivers what matters most: consistently precise and accurate results.

Specifications of the macro element analyzer:

High-temperature combustion unit

Quantitative sample digestion is achieved at up to 1,200 °C, or up to 1,800 °C when using tinfoil, and is backed by a ten-year furnace warranty. This ensures 100% recovery, even for samples that are difficult to combust. Jet injection of oxygen directly onto the sample creates the highest oxygen concentrations at the point of combustion, while minimizing gas consumption.

Largest weighing range

Sample weights can range from micro amounts (less than 1 mg) to macro quantities (up to 800 mg of soil), depending on requirements, and up to 20 mg of organic matter.

Largest dynamic range of element concentrations and element ratio

Up to 40 mg C abs, or 15 mg N abs, from ppm to 100%.

Steel combustion tubes

Robust steel tubes are used in the combustion and post-combustion furnace in CN and CHN modes, ensuring a long lifespan.

Purge and 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

Offering matrix-independent stability for months at a time.

PC-based instrumentation control

Full digitalization 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 60 samples – upgradeable to 120 – with 21 CFR part 11 functionality also available.

One simple instrument for all applications

The vario MACRO cube 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

The vario MACRO cube requires only 48 x 55 cm of benchtop space and runs on a single power supply (230, 110, or 100 V) along with two gas connections. Its efficient design supports extended maintenance-free operation.
