Accredited to ISO/IEC 17025:2017
Technical competence confirmed by Perry Johnson Laboratory Accreditation (PJLA) in biological, chemical and non-destructive testing.
Independently assessed, internationally recognized
ISO/IEC 17025:2017 is the international standard for the competence of testing laboratories. Our accreditation means an independent body has assessed our methods, instruments, people and quality system against it.

The instruments behind our results
The core techniques on our scope of accreditation, by type.
Triple quadrupole liquid chromatography mass spectrometry
Tandem mass spectrometry confirms each compound by its own ion transitions, at trace levels.
Triple quadrupole gas chromatography mass spectrometry
Tandem mass spectrometry for compounds best separated in the gas phase.
Inductively coupled plasma mass spectrometry
Elements ionized in an argon plasma and measured at trace levels.
High-performance liquid chromatography
Liquid chromatography with diode-array UV detection.
Headspace gas chromatography mass spectrometry
A headspace sampler heats each sealed vial and injects only the vapor, which is separated and identified by its mass spectrum.
Real-time polymerase chain reaction
Detects the DNA of specific microorganisms.
Also on our scope: water activity, moisture content and foreign material.
What accreditation and licensing ask of us, every day
State and city licensed
Licensed by the State of California and the City of Los Angeles to perform regulatory compliance testing.
Validated methods
Every compliance test method is validated or verified before it is used.
Traceable calibration
Instruments are calibrated with traceable reference standards, and the calibration is checked before and during each run.
Quality control in every batch
Blanks, spiked controls and replicates run alongside client samples, with set acceptance limits. A compliance batch that misses them is not reported.
Independent checks
We analyze proficiency test samples of unknown value against other laboratories, and PJLA assessors review our methods, records and competence on a continuous cycle.
Impartiality and confidentiality
Both are requirements of ISO/IEC 17025:2017 and apply to every compliance sample.
