Infrared Moisture Analysis Theory and Advantages

Infrared Moisture Analysis is a non-destructive, non-contact method for determining the moisture content of materials. Utilizing infrared radiation to penetrate the substance, this technique relies on the absorption of infrared energy by water molecules present within the medium.

Principle:

Infrared radiation is directed onto the sample, and its absorption is measured.
Water molecules absorb infrared energy in characteristic wavelengths.
The amount of absorption is proportional to the quantity of water present.

Advantages:

Rapid and Non-Destructive: Analysis results obtained quickly without damaging the sample.
Contactless Measurement: Can measure samples in situ or in motion, eliminating contamination concerns.
High Accuracy: Measurement accuracy is typically within +/- 1%.
Versatile: Applicable to a wide range of materials, including solids, liquids, and gases.
Real-Time Monitoring: Enables continuous monitoring of moisture content in real-time, making it ideal for process control.

How to Do Infrared Moisture Analysis?

Specific procedures for performing Infrared Moisture Analysis may vary depending on the equipment and software used, but the general steps include:

Calibrating the equipment using reference standards.
Placing the sample in the analysis chamber or directing the infrared beam onto the sample surface.
Recording the infrared absorption data.
Analyzing the data using software algorithms to determine the moisture content.

Applications:

Infrared Moisture Analysis finds applications in various industries, such as:

Pharmaceutical: Monitoring moisture content in tablets, capsules, and powders.
Food: Determining moisture content in grains, flour, and other food products.
Chemical: Measuring moisture in raw materials, intermediates, and finished products.
Textile: Controlling moisture content in fabrics and yarns.
