Infrared (NIR) Spectroscopy is a non-destructive testing technique that utilizes the interaction of infrared radiation with a sample. This interaction results in absorption, transmission, or reflection of radiation at specific wavelengths, providing information about the molecular composition and structure of the sample.

How to do moisture analysis?

Moisture analysis using NIR Spectroscopy is widely employed in various industries. The process involves the following steps:

1. Sample Preparation: The sample is prepared by grinding or homogenizing it to ensure a uniform and representative analysis.
2. NIR Spectroscopy Measurement: The prepared sample is placed in a designated sample holder within the NIR spectrometer. The spectrometer measures the absorption, transmission, or reflection of infrared radiation in the near-infrared (NIR) region (700-2500 nm).
3. Data Acquisition: The instrument collects and digitizes the spectral data, which represents the interaction of infrared radiation with the sample.
4. Calibration Development: A calibration model is developed using reference samples with known moisture content. This model establishes the relationship between the spectral data and the moisture content of the sample.
5. Moisture Prediction: The developed calibration model is then applied to predict the moisture content of unknown samples based on their NIR spectra.

Advantages of NIR Spectroscopy

• Rapid Analysis: Provides quick results, making it suitable for real-time monitoring and process control.
• Non-Destructive: Allows for repeated measurements on the same sample without damaging it.
• Versatility: Applicable to a wide range of materials, including solids, liquids, and gases.
• Cost-Effective: Requires minimal sample preparation and eliminates the need for expensive reagents or solvents.
• Reliable: Provides accurate and repeatable measurements when properly calibrated and operated.
