Moisture analysers, generally called “moisture balances”, are utilized to measure the moisture content in various kinds of samples including solids, liquids, and gases. Trace moisture in solids must be controlled for plastics, pharmaceuticals and heat treatment processes. Gas or liquid measurement applications include dry air, hydrocarbon processing, pure semiconductor gases, and bulk pure gases, dielectric gases like those in transformers and power plants, and natural gas pipeline transport.
Due to the slow pace of traditional and manual laboratory moisture testing methods, automated moisture analyzers have been developed and can reduce the time necessary for a test from hours to just a few minutes.
Moisture analyzers are utilized in different industries for many different purposes. They can be used in food industry to control the moisture. Excess amount of moisture in food may lead to staleness or bacterial growth. Furthermore, there are many food items which are sold by their weight; thus, it is important to make sure customers aren’t overpaying for water weight. On the other hand, too little moisture can reduce the calorie count or make the food dry. Moisture is an important factor affecting the consistency, taste, shelf appearance and many other factors in food.
Moisture analyzers are also frequently used in quality control and other laboratories. Moisture analysis is used in many fields to determine the water content in crude oil, fuel, sewage sludge and many other chemicals, solids and liquids.
Most moisture analyzers have a computer interface to assist with the observation and analyses in the drying process and its effects on the sample. They have the capacity to save the tests in their memory to repeat frequent testing parameters without having to set them up over and over again to assist with the elimination of down time.
How moisture analyzers work
Moisture analyzers utilize Loss On Drying (LOD) method to measure moisture. In this method, the moisture analyzer weighs a sample, heats it up to dry it, and weighs it again once it’s dry. The weight after drying is subtracted from the weight before, so the loss of moisture is determined using the loss of mass.
The heat generating system can vary from analyzer to analyzer. Some moisture analyzers use halogen and some use infrared or glass-free metal heaters positioned above a precision balance. Halogen moisture analyzers are quick, efficient and responsive. These types of moisture analyzers are ideal to use where there is no single setting that heats all samples evenly
Why is it used for Moisture Analysis?
A moisture analyser is extremely important because moisture analysis is necessary across a number of industries. For example, the measurement of moisture content is highly necessary in the food, pharmaceutical, textile and agricultural industries. This is because it affects quality control criteria such as weight, shelf life, pricing and quality.
For example, high levels of moisture can decrease the value of products and reduce shelf life due to a greater potential for microbial activity. Most products will have optimum moisture content for the highest quality and there are many laws and regulations set in place to determine the correct moisture content for sure regulated products. Are, there are national foods regulations defining the maximum moisture content permissible for certain food produce.
Therefore, moisture analysis is essential for compliance to such regulations and the production of a quality product. The best method for moisture analysis is via the use of a Moisture analyzer.
