Everything You Need to Know about Moisture Analyzers

Moisture analyzers, sometimes known as “moisture balances,” are instruments that are used to determine the moisture content of a variety of samples, including solids, liquids, and gases. Plastics, medicines, and heat treatment procedures all need the management of trace moisture in solids. Dry air, pure semiconductor gases, dielectric gases used in transformers and power plants, and natural gas pipeline transit are all examples of gas. or liquid measuring applications. Automated moisture analyzers have been created as a result of the sluggish speed of traditional and manual laboratory moisture testing procedures. They may cut the time required for a test from hours to just a few minutes. Moisture analyzers are used in a variety of sectors for a variety of objectives. They can be used to regulate moisture in the food sector. Staleness or bacterial development can result from too much moisture in meals.

Furthermore, many food items are offered by weight; therefore, it is critical to ensure that customers are not overpaying for water weight. Too little moisture, on the other hand, might lower the calorie count or make the meal dry. Moisture has a significant impact on the consistency, flavour, shelf appearance, and a variety of other aspects of food.

Moisture analyzers: What are they and how do they work?

Moisture analyzers measure moisture using the Loss On Drying (LOD) technique. In this approach, the moisture analyzer weighs a sample, warms it to dry it, and then weighs it again after it’s dry. The weight after drying is deducted from the weight before drying, and the loss of mass is used to calculate the moisture loss. The heat-generating mechanism differs from one analyser to the next. Halogen is used in some moisture analyzers, while others use infrared or glass-free metal heaters positioned above a perfect balance. Halogen moisture analyzers are fast, efficient, and flexible. These sorts of moisture analyzers are suitable for situations when there isn’t a single setting that warms all of the samples, such as where there isn’t a single setting that heats all of the samples.

What is the significance of moisture content measurement?

In most manufacturing and laboratory facilities, moisture content analysis is a crucial function of quality control. Moisture may affect a material’s physical characteristics such as weight, thermal expansion, amalgamation, electrical conductivity, and microbiological activity. To check the quality, alter production processes, and guarantee that goods satisfy rules and guidelines, it is necessary to test the water content of substances. Water content is critical in the processing and handling of cosmetics, medicines, food, personal care goods, pulp and paper products, specialised chemicals, and wastewater applications, to name a few.

Best practises suggestions

  • Ascertain that your sample preparation is uniform and that the sample’s whole surface area is exposed. If grinding or crushing is necessary, make sure it’s done consistently and without exposing the sample to heat. Make sure the sample is uniformly dispersed and not clumped in any way that prevents energy from entering and drying the material completely.
  • Allow plenty of time for cooling in between readings. If the machine is still hot from a prior run, it may influence the sample’s initial weight measurement, causing an error in the final percentage moisture content (per cent MC).

Moisture analyzers are also used in quality control and other labs. Moisture analysis is used to evaluate the water content of crude oil, gasoline, sewage sludge, and a variety of other chemicals, solids, and liquids in a variety of areas. The computer interface on most moisture analyzers aids in the monitoring and analysis of the drying process and its impact on the sample. They can save tests in their memory, allowing them to repeat frequently tested parameters without having to set them up again, reducing downtime.
