gravimetric analyzes (fat determination, dry matter, ash, protein,...)

Gravimetric analysis is a method in chemistry and analytics in which the mass of an analyte is measured directly or indirectly. This method is based on the premise that the mass of a substance is directly related to its quantity. It is a high-precision technique used in various scientific disciplines. There are two main types of gravimetric analysis: Direct gravimetric analysis: In this method, the analyte is directly converted into a measurable substance, which is then weighed. For example, the determination of chloride ions can be done by adding silver nitrate to form silver chloride, which is then filtered off, dried and weighed. Indirect gravimetric analysis: Here a compound with a known composition is created, which consists of the analyte and another reagent consists. By measuring the mass of the resulting product, the amount of analyte can be determined. An example of this is the determination of sulfur in a sample by forming barium sulfate.

The scale is required for precise measurement and differential weighing of substance quantities such as fat, protein, ash, dry matter and much more. Gravimetric analysis involves special filtration through an analysis filter. This analysis filter is weighed before and after filtration using a precise analytical balance to determine the total mass of the particles. This high level of accuracy is important for quality assurance!
