The lab.

Independent analytical laboratory
Analytical testing & contract research
Mission Hills, California

Premier Analytical Sciences is an independent analytical laboratory in Mission Hills, California. As a third party, it measures the purity, identity and quantity of research peptides, and it takes on contract research. Each certificate names its method, each vial is photographed on arrival, and each published record can be checked on the register.

Line 01

Third-party verification

Purity, identity, and quantity of research peptides, measured on the lab's own instruments for a commissioning party — on a certificate that is numbered and permanent whatever it says, and goes on the public register at that party's election.

Line 02

Contract research

Custom assay development and validation, analytical method development and optimization, preclinical and formulation studies, and regulatory data package preparation — from your protocol, or a method built for your project.

Line 03

Molecule & protein analysis

Accurate mass determination, structural elucidation and fragmentation analysis, purity and impurity profiling, peptide mapping, and identification of post-translational modifications.

Why trust us.

Every method named
Every vial photographed
Every claim checkable

A seal asks you to trust whoever granted it. This lab is arranged so a stranger does not have to trust anyone: the method is printed on the certificate, the vial is photographed before it is opened, and a record that has been published cannot afterwards be edited, unlisted, or quietly deleted — whether it flatters the material or not.

Ground 01

Through method

A number without its method is an opinion. Every value the lab releases carries the instrument and conditions that produced it — stated specifically enough for another chemist to check, not just impressive enough to read.

Named on every certificate

Ground 02

Through the photograph

Every vial is photographed as received — sealed, before it is given a lab number. What was tested is shown, not described, and the photograph stays on the record.

Ground 03

Through the register

Every certificate is numbered and permanent. The ones our customers publish go where anyone can read them, including the superseded and the withdrawn, and a published record cannot afterwards be edited, unlisted, or quietly deleted. A register that can only say yes is an advertisement.

Published · one-way · permanent

The register is the proof of all three. Open it and check.

Two founders
Named with their roles

Two people founded this laboratory, and their names go on it the way a signature goes on a certificate.

Founder 01

Michael Khoury

Co-founder · Chief Executive Officer

Founder 02

Donald Trujillo

Co-founder · Chief Scientific Officer

One client, quoted in his own words

“High-res MS spectra.” “Short turnaround.” “Courteous, professional personnel.”

Prof. Gagik Melikyan · California State University, Northridge

Three phrases, carried exactly as given. The register does not paraphrase.

Analytical instrumentation at the laboratory bench — The bench, not the lobby · the certificates cite HPLC-UV/MS and QTOF-MS · an illustrative photograph, not a claim about the facility

The particulars

Testing is commissioned; the result stands as measured. You pay for the analysis. You do not buy the result.
Every certificate names its commissioning party and cannot be changed after release.
Questions about a record go to the lab that signed it — not to the vendor who commissioned it.

Nothing on this page is a certification mark, and every certificate pertains only to the specific samples tested, for research purposes only.
