Elementar - Model vario MACRO cube -Organic Elemental Analyzer

for simultaneous, one sample CHNS, CHN, CNS, or CN determination in macro sized samples

made possible by our unique Advanced Purge and Trap (APT) technology

thanks to large sample volumes of up to 1.5 g

thanks to the integrated autosampler with up to 120 positions and low maintenance requirements

Highest versatility in a macro analyzer

The vario MACRO cube is designed for simultaneous determination of CHNS in samples up to the gram range, and represents the world’s first analyzer to make this possible in a single, fully-automated step. The analyzer can be set up in CHNS, CHN, CNS, or CN mode to ensure an optimal configuration, tailor-made to your analytical demands. For even higher versatility in your analysis, the addition of optionally available upgrade kits for the detection of oxygen, chlorine, total inorganic carbon (TIC), and total organic carbon (TOC) is possible at any time.

Simultaneous CHNS determination with highest precision and accuracy

The vario MACRO cube guarantees blank-free sample transfer thanks to our patented ball valve sample introduction, resulting in analysis results with highest precision and accuracy. The use of our Advanced Purge and Trap (APT) technology enables the instrument to measure samples with even the most challenging C:N elemental ratios of up to 7,000:1. Apart from that, the instrument is ideal suited for highly precise hydrogen concentration measurements.

Sample preparation reduced to a minimum

Save valuable time in sample preparation! The vario MACRO cube can handle large sample volumes of up to 1.5 g which allows analyzing even inhomogeneous matrices without time-consuming sample preparation like grinding or milling. In addition, the large sample weight allows the determination of smaller element concentrations, which accounts for the vario MACRO cube’s wide detection range.

Highest sample throughput and low maintenance through design

The vario MACRO cube can be equipped with a large autosampler with up to 120 positions that is reloadable at any position and time, enabling a blank-free sample transfer and unattended 24/7 operation with highest sample throughput. The long-term stable calibration reduces contact time with the instrument, as no calibration samples prior to analysis are required. This results in extremely low maintenance and highest system uptime. Whenever maintenance is necessary though, our user-friendly clamp connections system ensures a tool-free maintenance experience, while the slide-out furnace gives access to all important parts and guarantees a comfortable working posture.
