Residual Solvent

Unicorn Analytical Services provides high‑precision analytical testing to detect residual solvents and chemical contaminants that may remain from raw materials, extraction processes, or manufacturing operations. These evaluations are essential for ensuring product safety, regulatory compliance, and adherence to USP <467> and global quality standards.Our testing supports pharmaceuticals, dietary supplements, herbal extracts, cosmetics, and cannabis products requiring strict control of volatile and semi‑volatile impurities.

What we Offer

Using validated GC (USP <467>) and HPLC methodologies, our laboratory accurately identifies and quantifies both volatile organic solvents and non‑volatile chemical contaminants. Our methods are designed to meet regulatory expectations and provide manufacturers with the data needed for batch release, stability studies, and regulatory submissions.

We deliver:

• Highly sensitive detection of Class 1, 2, and 3 solvents

• Quantitative reporting with clear specification alignment

• Fast turnaround times for production‑critical testing

• Defensible data suitable for audits and compliance reviews

Test Available

• Ethanol Determination (USP <467>)
• Residual Solvents Panel (USP <467>)
• Dicyandiamide

Why It Matters

Accurate residual solvent and contaminant testing helps ensure:

• Product safety by identifying harmful chemical residues

• Regulatory compliance with USP <467>, FDA, Health Canada, and ICH guidelines

• Manufacturing quality control by verifying proper solvent removal

• Consumer protection from toxic or unacceptable impurities

• Audit‑ready documentation for GMP‑regulated environments
