3 Easy Steps for Measuring Moisture Content
Measuring the moisture content of a substance is vital for many industries. Moisture content can indicate several properties such as the quality of a substance, its shelf life and freshness. These contribute to the price of an item, so it is vital for businesses when deciding on their costs. In this article we will outline how to measure moisture content and why you should measure moisture content.
What is ‘Moisture Content’?
It is important to note that moisture is not just water. Water specifically refers to molecules with the chemical formula H2O, however moisture is a wider term that includes anything that evaporates from a substance when heated, for example solvents, flavourings, fats and other substances.
There are 3 types of moisture content that all must be considered when measuring moisture content:
Surface moisture – Moisture adhered to the surface sample, sometimes referred to has hygroscopic, adhesive or free water. This is the least difficult moisture to remove.
Absorbed moisture – This moisture has travelled into the pores and capillaries of the sample. Sometimes called equilibrium moisture.
Chemically bonded moisture – Moisture molecules are chemically bonded to the sample at a molecular level. This is the most difficult type of moisture to remove.
Why Measure Moisture Content?
The moisture content of a substance can impact its overall quality, so measuring moisture content is vital to consistently uphold the high standards of products. For example, in foods, moisture content can impact the taste, smell and shelf life of a product. Optimising the moisture content of food can also help to reduce food waste. In agriculture, the moisture content of soil can help determine optimal growing conditions for plants and crops.
Most industries have laws to regulate the moisture content of substances. This makes a moisture content analyser an essential piece of equipment for many research and development labs, as well as quality control facilities.
Measuring Moisture Content using a Moisture Content Analyser
Moisture content can be measured in just 3 steps when using a Moisture Content Analyser:
- Find the initial weight of the sample by weighing the sample before drying
- Set parameters (temperature, time) and dry sample
- Weigh sample after drying and compare to the initial weight to calculate the Loss on Drying.
