The world’s first CHNS macro elemental analyser with crucible technology

Elemental analysis is essential for understanding the composition of organic and inorganic materials across environmental studies, agriculture, petrochemistry, energy, and industrial quality control. Yet, accurately determining carbon, hydrogen, nitrogen, and sulphur (CHNS) becomes particularly challenging when working with heterogeneous or inhomogeneous samples, where particle size, density, or moisture variability can compromise representativeness.

The EMA 402XL sets a new benchmark by enabling reliable CHNS determination on macro samples, ensuring more representative results and improved reproducibility across complex matrices.

Why Macro CHNS Analysis Matters

Traditional elemental analysers typically rely on small sample portions, which may not fully reflect the composition of heterogeneous materials such as soils, fuels, biomass, or waste. Increasing sample size significantly improves data reliability, especially when dealing with variable matrices.

The EMA 402XL addresses this need through innovative crucible technology, allowing direct analysis of larger sample weights with minimal preparation while maintaining high analytical precision.

Advanced Technology for Complex Samples

The EMA 402XL combines automation, precision detection, and robust combustion to simplify CHNS analysis in demanding applications.

Key innovations include:

• Reusable ceramic crucibles for direct macro sample analysis and reduced waste
• Automated vertical combustion system ensuring complete oxidation of complex matrices
• Dual detectors for accurate quantification of carbon, hydrogen, nitrogen, and sulphur
• 100-position autosampler for sequential or non-sequential unattended operation

This fully automated workflow streamlines laboratory operations, reduces manual handling, and improves safety, while maintaining excellent reproducibility even with challenging samples.

Smart software and connectivity tools enable real-time monitoring, remote supervision, and efficient data management, supporting continuous operation with low running costs.

Applications Across Multiple Industries

Thanks to its ability to process larger and heterogeneous samples, the EMA 402XL supports a wide range of analytical needs:

• Environmental and agricultural labs: soils, sediments, fertilisers, and organic amendments
• Energy and petrochemical sectors: fuels, oils, coal, coke, and bio-based materials
• Waste management and circular economy: municipal, industrial, and organic waste characterisation

In addition to CHNS determination, the system can monitor oxygen consumption during combustion, enabling the calculation of Total Oxygen Demand (TOD) to better evaluate energy potential and sample composition.

A New Standard for Macro CHNS Analysis

With its combination of crucible technology, automation, and precision detection, the EMA 402XL empowers laboratories to analyse complex and heterogeneous samples with confidence, improving reproducibility and workflow efficiency.
