Moisture Content and Water Activity Testing

Accurate moisture content measurements ensure proper product storage, quality preservation, and regulatory compliance. We provide precise water activity and moisture analysis.

Moisture Analysis Parameters

  • Moisture Content (%): Percent of water by weight
  • Water Activity (aw): Available moisture for microbial growth
  • Equilibrium Moisture: Moisture level at storage humidity

Why Moisture Testing Matters

  • Shelf life and product stability
  • Prevention of mold and microbial growth
  • Preservation of cannabinoids and terpenes
  • Meeting regulatory requirements
  • Quality control and consistency
  • Consumer safety assurance

Optimal Moisture Ranges

  • Cannabis flower: Typically 6-12% moisture content
  • Hemp flower: Similar optimal range for preservation
  • Extracts/Concentrates: Lower moisture (varies by product type)
  • Edibles: Product-specific moisture requirements

Testing Methods

  • Thermogravimetric analysis (drying method)
  • Karl Fischer titration for accurate water quantification
  • Water activity instruments (Aw measurement)
  • Rapid moisture meters for quick results

Storage Implications

Proper moisture content helps ensure:

  • Long shelf life without degradation
  • Potency preservation
  • Prevention of mold formation
  • Maintenance of product quality

Sample Requirements

  • Minimum: 3-5 grams
  • Room temperature samples
  • Avoid exposure to air/humidity
  • Sealed containers
