Moisture content

Moisture analysis is commonly used in:

• Agricultural and soil research
• Seed and grain research
• Biomass
  
• Chemical analysis
• Pharmaceuticals
• Cosmetics and beauty products
• Food and beverage
• Geological sciences
• Natural products and dietary supplements
• Petroleum products
• Pharmaceutical packaging
• Plastics and films
• Production mining
• Pulp and paper products

Near-infrared (NIR) spectroscopy can detect the water content and activity in a wide range of materials, and over a large range of concentrations. 

ASD’s portable and at-line Vis/NIR systems are ideally suited for the real-time measurement of moisture with easy-to-use, non-destructive testing in just about any environment. 

Concentrations ranging from 0.01% and up can be accommodated by selection of the appropriate wavelength range, thus making ASD’s technology the ideal tool for accurate and flexible moisture analysis in raw and in-process materials, as well as finished product.

• No sample prep
• Accurate results are real-time
• Rapid, non-destructive
• Measure where and when you need it
• Decrease out-of-spec product
• Improve overall product quality

Traditional laboratory methods such as loss on drying (LOD) require time consuming steps such as oven heating and dry time in a desiccator to determine the loss of weight. Even newer automated moisture analysis equipment still requires a few minutes of drying time to determine the drying curve. 

All of these techniques require sample prep, and upon completion of the procedure, the sample is destroyed.
