An organic substance is a chemical compound whose structure is mainly based on carbon. These substances can be of natural origin, from biological sources (such as plants, animals or micro-organisms), or synthetic, i.e. man-made. Organic substances include a wide range of compounds, such as [hydrocarbons](https://filab.fr/nos-prestations/analyse/analyses-chimiques/hydrocarbures-aromatiques-polycycliques-hap.md) ([carbon](https://filab.fr/nos-prestations/analyse/laboratoire-analyses-metallurgiques/laboratoire-dosage-carbone-c.md) and [hydrogen](https://filab.fr/nos-prestations/analyse/laboratoire-analyses-metallurgiques/laboratoire-dosage-hydrogene-h.md)), [alcohols](https://filab.fr/nos-prestations/analyse/analyses-chimiques/etude-alcools-gras.md), [organic acids](https://filab.fr/nos-prestations/analyse/analyses-chimiques/laboratoire-analyse-acides-organiques.md), esters, proteins, lipids and carbohydrates. They are characterised by the presence of carbon atoms linked together or with other elements such as [hydrogen](https://filab.fr/en/our-services/our-analysis-services/metallurgical-analysis-laboratory/laboratory-analysis-hydrogen.md), [oxygen](https://filab.fr/en/our-services/our-analysis-services/metallurgical-analysis-laboratory/laboratory-oxygen-determination.md), [nitrogen](https://filab.fr/en/our-services/our-analysis-services/metallurgical-analysis-laboratory/determination-nitrogen-content.md),[sulphur](https://filab.fr/en/our-services/our-analysis-services/halogen-analysis-laboratory/laboratory-sulfur-determination.md), etc. They are ubiquitous in nature and play a key role in many biological and industrial processes, including energy production, materials synthesis and biochemical reactions. ### What is organic chemistry? Organic chemistry focuses on the study of carbon-based compounds, whether of natural or synthetic origin. In an industrial context, identifying the molecules present and knowing the chemical elements of your products enables you to : Guarantee their compliance with your declarations and regulatory requirements. Optimise your production processes to prevent any risk of product failure. Ensuring the compatibility of a chemical substance with its environment. Depending on the nature of the samples and the quantification thresholds required, various more or less sophisticated analytical techniques can be deployed. Calling on a specialist laboratory with extensive [analytical resources](https://filab.fr/en/our-technical-resources.md) guarantees you the expertise you need for your basic analyses. ## Our solutions: measure molecules by GC-MS and HPLC in your matrices ### Why choose FILAB for the determination of molecules by GC-MS and HPLC?
