Elemental combustion and fusion analysis
Elemental analysis of C, H, N, S and O
Choose the technique by matrix: FlashSmart for organic samples and some inorganic; EMIA and EMGA especially for steels, alloys, metals and technical materials.
CHNSO
Direct response
FlashSmart determines CHNS/O mainly in organic samples — food, biomass, fuels and polymers — and also in some inorganic matrices such as soils, fertilizers, materials and ores, when the method is compatible. EMIA and EMGA are platforms dedicated to the universe of steels, irons, alloys, metals and inorganic materials: EMIA for C/S and EMGA for O/N/H.
Integrated portfolio
The matrix defines the analytical path
First identify the nature of the sample. Then confirm the elements, the expected range, the required method and throughput.

Answers to guide the project
Which instrument should be used to analyze C, H, N, S and O?
It depends first on the matrix and after the elements. FlashSmart serves CHNS/O mainly in organics and also in soils, fertilizers, materials and some compatible ores. EMIA is dedicated to C/S in steels, alloys, ores and inorganic materials. EMGA is dedicated to O/N/H in metals, steels, alloys and metallic powders.
Are FlashSmart, EMIA and EMGA competing technologies?
No. They occupy complementary functions inside the lab. In a multi-technique structure, each platform meets specific combinations of elements, samples and analytical principles.
Does the same equipment measure all elements in any matrix?
No. Compatibility depends on the principle, preparation, configuration and method. The correct definition avoids extrapolating the application of a platform for matrices that require another analytical process.
How does SENS help define the configuration?
The evaluation considers matrix, elements, concentration range, available mass, throughput, gases, automation and method requirements before the technical proposal.
