Hawaii Agriculture Research Center (HARC) |
Specializing in:
EPA registration of pesticides
Plant metabolism studies
Chemical analysis of pesticides in water, soil, and plant tissues
Groundwater, soil leaching, and environmental studies to monitor the movement of Crop Protection Chemicals away from target areas
Method development
Other chemical analyses
The Hawaii Agriculture Research Center (HARC) Analytical Chemistry Laboratory and affiliated research departments provide chemical analysis, quality assurance, and environmental regulatory services. Laboratory services include high performance liquid chromatography and gas chromatography determinations of organic compounds, auditing of quantitative studies, and critical reviews of chromatographic raw data to determine the accuracy of compound identification. Gas chromatographs are equipped with five different types of detectors including mass spectrometry.
Since the early 1950's, HARC has been engaged in the registration and reregistration of chemicals needed by the agricultural industry. Pesticide registration requires compliance with the EPA Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), and in particular, Section 40 of the Code of Federal Regulations, Part 160, Good Laboratory Practices.
In recent years, HARC has successfully undergone rigorous facility inspections by the Quality Assurance personnel from most of the major chemical companies and also by the EPA. HARC conducts field, processing, and/or laboratory phases of magnitude of residue and metabolism studies. The Analytical Chemistry Laboratory personnel are experienced in methodologies used to analyze for compounds in difficult matrices.
