Batch-level Testing

GC/MS testing and COA provided on request so formulators can validate quality.

Comprehensive Batch Testing and COA Documentation

Every batch we produce goes through complete analytical testing before it ships. This isn't spot-checking or random sampling. It's comprehensive verification that covers composition, purity, and safety.

Here's what we test:

Gas chromatography-mass spectrometry (GC/MS) confirms compositional profile and menthol content. Physical-chemical testing verifies specific gravity, optical rotation, and refractive index against specifications.

Safety screening includes pesticide residue testing, heavy metals analysis, and microbial limits verification. These tests ensure the material meets safety standards for your intended application—whether that's food, cosmetics, pharmaceuticals, or industrial use.

Documentation you can use:

Every test result gets documented in a Certificate of Analysis (COA) with full traceability to production records. The COA links directly to the batch code on your material, so there's never confusion about which test results apply to which shipment.

Need to review our testing scope before purchasing? We provide redacted COA previews during procurement assessment. Your R&D team can evaluate our analytical methods and parameter limits before committing to an order.

When material arrives, you receive the complete COA. It ships with your order and remains available throughout the product lifecycle for quality verification, regulatory audits, or customer inquiries.

Why this matters:

Batch-level testing eliminates guesswork. Your formulation team knows exactly what they're working with. Your quality team has documentation that supports compliance requirements. Your procurement team can validate supplier quality claims with actual data.

Testing isn't an optional service we offer. It's built into how we manufacture peppermint oil.
