VHR Analytical Services offers the following testing services;

Analysis of Samples from In-life Animal Phase Studies

All organisations registering agrochemicals need accurate and timely data generated from methods which are validated to comply with the requirements of the Australian Pesticides and Veterinary Medicines Authority (APVMA), New Zealand’s Food Safety Authority (ACVM) and other international regulatory agencies (EMEA). The vital aspect in meeting deadlines for product registration is the use of experienced field staff and laboratory services.

Our residue testing laboratory is equipped with the latest technology to ensure that crucial deadlines are met. State of the art equipment includes:

  • UPLC/MS/MS (Ultra Performance Liquid Chromatography – Triple Quadrupole)
  • HPLC (High Performance Liquid Chromatography with both conventional and Acquity UV/Visible and Fluorescence detectors)

VHR Analytical Services is continually improving to keep pace with developments in analytical chemistry and changes in regulatory requirements. In fact we have NATA Accreditation to ISO/IEC 17025 for the analysis of veterinary chemicals and to conduct studies in compliance with the OECD Principles of Good Laboratory Practice.

By using Veterinary Health Research Pty Ltd and VHR Analytical Services for your product registration you can be sure that you will have a dedicated research/analytical team committed to providing the best service possible.
