Fluorescence Spectroscopy

Fluorescence spectroscopy is a powerful analytical technique commonly utilized to determine the moisture content in diverse materials. Several official methods have been established to yield precise and accurate results.

Official Methods

ASTM E2414: Standard Practice for Determination of Moisture Content by Fluorescence Spectroscopy
ISO 662: Determination of Moisture Content by Karl Fischer Titration
AOAC Official Method 950.46: Moisture in Meat and Meat Products by Karl Fischer Titration
AACC Method 44-15: Moisture Determination Using Karl Fischer Titration
US Pharmacopeia (USP 829): Determination of Moisture Content

Technical Details

Fluorescence spectroscopy involves exposing a sample to a specific wavelength of light. The sample emits measurable fluorescence intensity that is directly proportional to the moisture content. This technique is highly sensitive and accurate, allowing for precise measurements of moisture in various materials, including food, pharmaceuticals, and industrial products.

Applications

Moisture analysis in food products, such as meat, dairy, and cereals
Moisture monitoring in pharmaceutical formulations
Quality control in industrial processes involving drying and moisture removal
