Organic substances are generally referred to as substances in the structure of living organisms or containing organic compounds. Organic substances are not naturally present, but are synthesized only during metabolism in the organism. For example, processed organic materials are used as fertilizers in agricultural activities. Organic materials used as fertilizers regulate the soil structure and are particularly preferred in organic farming production methods.

Organic substances, which can be produced by living organisms through synthesis and which form the building blocks of cells, meet the energy requirements of the cells and undertake regulatory tasks such as hormones in living organisms. Organic substances that can be defined as biological molecules carrying carbon atoms are basically composed of the following seven groups: carbohydrates, proteins, lipids (fats), nucleic acids, enzymes, vitamins and hormones. Inorganic compounds are generally molecules which do not carry carbon (such as anions or cations). Molecules in the structure of living organisms that do not contain carbon atoms are inorganic compounds (such as water, various acids, bases and salts).

The human body needs organic and inorganic compounds. Inorganic compounds, on the other hand, are synthesized by external foods.

Determination of total organic matter is the process of measuring the amount of reducing agents present in the water in the minimum amount. Organic substances in water are formed as a result of a number of reactions due to environmental or microbial pollution. Dissolved substances in water are organic and inorganic in structure. The total amount of organic matter in the waters indicates the oxidability of the waters. The determination of oxygen in mg / l in these waters is considered as an indicator of the water pollution of organic materials.

Organic and total organic matter determination studies are carried out in authorized laboratories within the scope of chemical tests and standards and published analysis methods and test criteria accepted by the institutions operating in our country and foreign countries are followed in the analyzes. In addition, reliable and impartial service is provided in these laboratories.
