WHAT WE BELIEVE

Independent analysis isn’t a marketing line. It’s a promise that the person looking at your chromatogram has no reason to round up.

How a sample becomes
a certificate.

Every sample that comes through our door moves through the same five steps. No shortcuts for rush orders. No unnamed hands in the middle.

1

Intake.

Your sample arrives. We photograph it, weigh it, log every detail, and assign it a tracking number that will appear on every piece of paper tied to it.

2

Prep.

A named analyst prepares the run: dissolutions, dilutions, internal standards. Their initials go in the log.

3

Run.

HPLC or LC‑MS per the method for your compound. System suitability standards bracket your sample on either side.

4

Review.

A second analyst reviews the chromatogram independently. Nothing ships with one set of eyes on it.

5

Sign.

The COA is digitally signed, hashed, and published. Anyone with the link can verify the signature matches the raw data.

THE FOUR PILLARS

Why you can trust ECA.

01

Mission

Transparency, precision, trust. Every sample is handled with strict chain-of-custody protocols.

02

Equipment

We run Agilent 1260 Infinity II HPLC systems paired with an Agilent LC/MSD XT for compound identification and quantitation.

03

Accuracy

ISO/IEC 17025-aligned testing procedures.

04

Data Integrity

All results are digitally signed and verifiable. Raw chromatographic data is retained for three years. Samples are destroyed after analysis per our standard operating procedures.
