Moisture Analysis and Measurement
Moisture plays a vital role in various industries, influencing the quality, stability, and durability of products. To ensure precise moisture management, moisture mapping emerged as a technique for determining the moisture content distribution within a material.
What are the Official Methods of Moisture Content Determination?
Several official methods have been established by regulatory bodies to accurately determine the moisture content of materials:
- Karl Fischer Titration: Employs a chemical reaction to determine the amount of water present in a sample.
- Gravitational Oven Drying: Involves heating a sample at a specific temperature to remove moisture and calculate the weight loss.
- Microwave Oven Drying: Utilizes microwave radiation to rapidly remove moisture from a sample.
- Loss on Ignition: Measures the weight loss of a sample upon ignition at a high temperature, indicating the moisture content.
- Near-Infrared (NIR) Spectroscopy: Determines moisture content by analyzing the absorption pattern of NIR light passing through a sample.
The appropriate method is chosen based on the material’s properties, accuracy requirements, and available equipment.
