Testing & Quality
E-HPLC Tested Chondroitin
The testing method matters more than you think. Not all analytical approaches are equal — and with Chondroitin, that difference is critical to label accuracy and formulation integrity.
Method 1
CPC (Titration)
- Measures the entire molecule as a whole
- Commonly used for formulation calculations
- Does not confirm molecular identity
- Limited specificity for label claim validation
Method 2
Standard HPLC
- Measures total polysaccharide content
- Does not differentiate similar compounds
- May overestimate true Chondroitin content
- Moderate specificity for identity verification
Method 3
Enzymatic HPLC (E-HPLC)
- Breaks Chondroitin into specific disaccharide components
- Measures individual structural markers (4S / 6S ratios)
- Provides high specificity and accurate identification
- Detects non-specific or adulterated materials
- Aligns with modern analytical expectations
Recommended
Method 2
Standard HPLC
- Measures total polysaccharide content
- Does not differentiate similar compounds
- May overestimate true Chondroitin content
- Moderate specificity for identity verification
Key Analytical Considerations
- Disaccharide composition (4S / 6S ratios)
- Identity confirmation prior to potency analysis
- Acceptable variance between analytical methods
- Additional purity indicators: sulfates, chlorides
- Electrophoretic profile verification
Building Confidence Into Your Formula
- Verify identity before assessing potency
- Understand which method your supplier uses
- Align testing with modern analytical standards
- Work with suppliers who prioritize transparency
- Request documentation and COA traceability
