What Golden Pacific Laboratories does

Golden Pacific Laboratories, LLC (operating as "Golden Pacific Labs") is a privately-held contract analytical chemistry laboratory headquartered at 4720 West Jennifer Ave., Suite 105, Fresno, California. Founded in 1997 and operating continuously for 25+ years, the company delivers GLP-compliant (Good Laboratory Practice) analytical services to agricultural, residential, and occupational exposure study sponsors, with the agricultural vertical — magnitude of residue, field/aquatic dissipation, and ILV studies — described as the primary customer segment.

The company's technical platform combines triple-quadrupole mass spectrometry (AB Sciex API 6500+, API 5000, and API 4000 LC/MS/MS with APCI and Turbo Ion-spray), gas chromatography with multiple detectors, Dionex ASE200 accelerated solvent extraction, and automated batch processing equipment. A state-of-the-art Environmental Exposure Chamber (15.5 x 15.5 x 8 feet) with tightly controlled temperature, humidity, and air quality — and an adjustable flow rate of 0.5 to 6 air changes per hour — extends the offering into human exposure, transferability, and clinical assessment studies, including IRB-approved protocol design, subject recruitment, exposure, and sample collection.

Golden Pacific Laboratories operates a direct B2B enterprise sales motion, quoting project-by-project on study scope and complexity. Its Quality Assurance Unit reviews and audits each study from protocol initiation to final report. The company is single-site, serves clients primarily within California's Central Valley, and is privately held as an LLC with no disclosed funding, M&A, leadership changes, or headcount growth signals in the available data.

Core offering

Golden Pacific Laboratories is a contract analytical chemistry laboratory that provides GLP-compliant method development, method validation, and testing services. The company's portfolio centers on residue studies (magnitude of residue, field and aquatic dissipation, ILV), exposure studies (re-entry, worker, residential/indoor), and full study directorship including IRB/HSRB protocol review, subject recruitment, exposure, sample collection, and analysis. Services are delivered from a single Fresno, California facility using LC/MS/MS, gas chromatography, accelerated solvent extraction, and a dedicated environmental exposure chamber.

Product overview

Golden Pacific Laboratories offers a unified portfolio of GLP-compliant analytical chemistry contract services centered around analytical method development, validation, and regulatory testing. The core service portfolio includes Analytical Chemistry Solutions for agricultural, residential, and occupational exposure assessment, supported by an Environmental Exposure Chamber for human exposure studies. Key service offerings include re-entry studies, magnitude of residue studies, field and aquatic dissipation studies, and indoor exposure studies. The company operates LC/MS/MS and gas chromatography instrumentation and provides study directorship, project management, and IRB/HSRB protocol review services. All services are delivered under GLP regulatory compliance with Quality Assurance oversight.
