Ash analysis
Ash analysis of cannabis products
Ash analysis is used to determine the total inorganic content of cannabis products and provides an important indicator of product purity and quality. Elevated ash values may indicate contamination, improper processing, or the presence of extraneous inorganic material.
Pharmacopeial compliance: EP <2.4.16> & USP <561>
We align our ash testing protocols with the European Pharmacopoeia (EP), which is a global benchmark for determining the quality of herbal drugs and preparations.
- Methodology: Analysis performed according to EP <2.4.16> or USP <561> (Total Ash).
- Purpose: This test measures the amount of residual substance remaining after incineration, helping to detect the presence of physiological or non-physiological inorganic impurities, such as sand, soil, or added mineral matter.
Eurofins Experchem offers validated ash analysis for cannabis flower and derived products to support compositional assessment and compliance with applicable pharmacopoeial and regulatory expectations. Our testing services help manufacturers monitor product consistency and support both domestic and international regulatory requirements.
