Infrared Spectroscopy (NIR) is an innovative technique employed in a multitude of industries to ascertain the moisture content of diverse materials.

How does it work?

• NIR spectroscopy utilizes near-infrared light to interact with molecular bonds within the material.
• The absorption pattern of this light offers insights into the molecular structure and composition, including moisture content.
• NIR equipment projects near-infrared light onto the sample, and the light absorbed by the sample is measured.
• The moisture content is then determined by analyzing the absorption pattern.

Advantages of NIR

• Non-destructive: NIR testing does not harm or alter the sample, making it suitable for repeated measurements.
• Rapid: NIR provides immediate results, enabling quick decision-making and real-time quality control.
• Accurate: NIR offers precise moisture measurements, ensuring reliable and consistent results.
• Versatile: NIR can be employed across various industries and applications, including food, pharmaceuticals, and agriculture.

Equipment Used for Moisture Testing with NIR

The primary piece of equipment used for NIR moisture testing is a near-infrared spectrometer. This device comprises:

• A light source that emits near-infrared light.
• A sample chamber where the material is placed.
• A detector that measures the light absorbed by the sample.

The spectrometer analyzes the absorption pattern of the light to determine the moisture content of the material.
