Know what is really in your product.

G2 Analytical's Botanical Authenticity & Adulteration Screening Panel provides a practical, evidence-based investigative tool for evaluating the identity and safety of botanical ingredients.

The 38-target HPLC-PDA screening method allows for the rapid identification of specific botanical markers and potential adulterants, providing actionable data for supply chain verification and product quality investigations.

The screening library currently includes 38 targeted compounds and is periodically updated as G2 Analytical expands its analytical capabilities. Screening results are qualitative; additional analysis may be recommended depending on the sample and analytical question.

Verify botanical composition

Confirm that the specified botanical materials are present in your raw materials or finished products.

Investigate unexpected compounds

Identify unknown peaks or signals that may indicate contamination, degradation, or adulteration.

Evaluate supplier materials

Screen new ingredients against a library of common botanical adulterants before they enter production.

Determine next analytical steps

Use qualitative screening data to decide if quantitative analysis or structural identification is required.
