Laboratory Weighing - Moisture Content Determination - Monitoring and Testing

The moisture content influences the physical properties of a substance such as weight, density, viscosity, refractive index, electrical conductivity and many more. Chemical, thermogravimetric or loss on drying techniques are used to determine this content.

Why measuring moisture ?

Most natural products contain moisture. The water content per se is seldom of interest. Rather, it shows whether a product intended for trade and production has standard properties such as

  • Storability
  • Agglomeration in the case of powders
  • Microbiolgical stability
  • Flow properties, viscosity
  • Dry substance content
  • Concentration or purity
  • Commercial grade (compliance with quality agreements)
  • Nutritional value of the product
  • Legal conformity (statutory regulations governing food)
