The science

Our Testing Technology

Our lab draws on a full suite of modern analytical instruments. We select the techniques that fit each supplement — this page explains, in general terms, how they work.

Core principles

How we see what's inside

Chromatography

Chromatography separates the many compounds in a supplement using a specialized column, so each ingredient can be analyzed individually.

Mass Spectrometry

Mass spectrometry identifies and quantifies the separated compounds with high precision — confirming both what is present and how much.

The instruments

A full analytical toolkit

A look at the techniques a professional lab can bring to supplement analysis. The right combination depends on the product.

HPLC

High-Performance Liquid Chromatography

Separates a sample into its individual components so each compound can be measured on its own — a workhorse for verifying potency.

LC-MS/MS

Liquid Chromatography–Tandem Mass Spectrometry

Pairs chromatography with tandem mass spectrometry to identify and quantify compounds, including peptides, with high specificity.

GC-MS

Gas Chromatography–Mass Spectrometry

Separates and identifies volatile compounds and residual solvents that liquid methods may not capture.

ICP-MS

Inductively Coupled Plasma Mass Spectrometry

Detects trace heavy metals — such as lead, arsenic, cadmium and mercury — down to very low concentrations.

UV-Vis

UV-Visible Spectroscopy

Measures how a sample absorbs ultraviolet and visible light to support quantitative assays of certain actives.

FTIR

Fourier-Transform Infrared Spectroscopy

Fingerprints molecular structure to help confirm the identity of raw materials and finished products.

Karl Fischer

Karl Fischer Titration

A precise technique for determining moisture (water) content, which can affect a product's stability and dosing.

Micro

Microbial Screening

Screens for microbial contamination to help support overall product safety.

Not every method applies to every product. We select the techniques most appropriate for your supplement — this overview is informational and not a commitment to any specific procedure.

Precision you can rely on

These methods can detect ingredients at very low concentrations and distinguish between closely related compounds — essential for verifying peptides and actives, and for screening contaminants or fillers.

The result is a transparent, defensible measurement of what your supplement actually contains, presented in a clear, easy-to-read report.

7-day turnaround on most reports.
