What is NIR Moisture Analysis

What is NIR Moisture Analysis?

Near infrared (NIR) moisture analysis is a non-destructive and rapid method for determining the moisture content of a sample. It is based on the principle that the absorption of NIR light by water molecules is proportional to the water content of the sample.

Applications of NIR Moisture Analysis

NIR moisture analysis is used in a wide variety of industries, including food, pharmaceutical, and chemical manufacturing. Some common applications include:

Measuring the moisture content of incoming raw materials
Controlling the moisture content of products during manufacturing
Verifying the moisture content of finished products

Benefits of NIR Moisture Analysis

There are several benefits to using NIR moisture analysis, including:

Speed and accuracy: NIR moisture analysis is a very fast and accurate method for measuring moisture content.
Non-destructive: NIR moisture analysis does not damage the sample, making it ideal for use on delicate or valuable materials.
Versatile: NIR moisture analysis can be used to measure the moisture content of a wide variety of materials, including solids, liquids, and gases.

How to Perform NIR Moisture Analysis

Performing NIR moisture analysis requires the following steps:

Prepare the sample by grinding or crushing it to a fine powder.
Place the sample in a sample cup or holder.
Insert the sample into the NIR moisture analyzer.
The analyzer will emit NIR light through the sample and measure the amount of light that is absorbed by the water molecules.
The analyzer will then calculate the moisture content of the sample.

Conclusion

NIR moisture analysis is a reliable and versatile method for measuring the moisture content of a wide variety of materials. It is a valuable tool for quality control and process monitoring in a variety of industries.
