What is GC-MS Testing?

Gas Chromatography-Mass Spectrometry (GC-MS) is the gold standard for analyzing essential oils. It identifies and quantifies the chemical components in your oil — providing a complete profile of what’s inside.

Your GC-MS report will show key constituents like linalool, linalyl acetate, camphor, and others, confirming both purity and quality.

Why Should You Test Your Lavender Oil?

Verify Purity & Authenticity

Confirm your oil is truly lavender, free from dilution or contamination. Build trust with buyers and consumers.

Understand Your Unique Profile

Every distillation is unique. Learn exactly how your cultivar, field, and harvest timing affect the final oil.

Refine Your Craft

Improve your distillation process over time. Testing helps you fine-tune for better yield, quality, and consistency.

Support Marketing & Sales

Confidently communicate your oil’s quality to wholesale buyers, formulators, and retail customers — backed by science.

Protect Your Reputation

A professional analysis safeguards your credibility and helps uphold industry standards.

Why It Matters to Our Industry
