You wish to carry out CHNSO analysis in the laboratory
FILAB offers CHONS elemental analysis testing in an ISO 17025-accredited laboratory (COFRAC No. 1-1793).
Using state-of-the-art technology, our team of experts determines the elemental composition of your samples with high precision, whether for quality control, regulatory compliance, or research and development.
First of all, the acronym CHNSO stands for Carbon, Hydrogen, Oxygen, Nitrogen and Sulphur.
These elements are the main components of living organisms and are therefore found in many products based on organic compounds.
Generally speaking, these elements are very abundant and it is therefore necessary to be able to determine the precise proportions of these elements in the products studied.
CHONS elemental chemical analysis therefore consists of determining the proportions of atoms of each chemical element present in the composition of a substance or product.
Thus, only a laboratory with state-of-the-art analytical equipment allowing highly accurate elemental analysis is able to perform CHONS analysis.
What is CHNSO (CHNS-O) analysis?
CHNSO analysis—also known as CHONS analysis or CHNOS analysis—is an organic elemental analysis method that measures the proportion of
- Carbon (C),
- Hydrogen (H),
- Oxygen (O),
- Nitrogen (N),
- and Sulfur (S) in a material.
These techniques are widely used to determine elemental composition in solids, liquids, and powders across various industries.

FAQ
CHONS stands for Carbon (C), Hydrogen (H), Oxygen (O), Nitrogen (N), and Sulfur (S)—the five key elements measured in this type of analysis.
Yes, CHONS and CHNSO refer to the same elemental analysis method, just with a different order of the letters.
We can analyze solids, liquids, and powders, including organic and inorganic materials.
Pharmaceutical, cosmetic, polymer, metallurgy, aerospace, and luxury goods sectors all use this method for compliance, quality control, and R&D.
It ensures our methods and results are recognized internationally for their accuracy and reliability.
Yes, combined with ICP-MS or ICP-OES, CHONS analysis can be part of a trace element analysis strategy.
