Good Laboratory Practice

The primary benefit of Good Laboratory Practice (GLP) is data integrity. This ensures that data is accurate, secure, attributable, available and reliable. RPS conducts a wide range of tests to evaluate chemical properties of Agrochemicals in compliance with OECD guidelines and compliance.


GLP is a quality control system covering the organisational process and the conditions under which non-clinical health and environmental studies are planned, performed, monitored, recorded, reported and retained (or archived).

Any pharmaceutical, biological or chemical product developed around the world requires mandatory testing and tight regulations. This demonstrates they are safe for their intended use by humans, animals and in the environment. In the UK, testing is regulated via Good Laboratory Practice (GLP) Regulations and compliance is monitored by the UK GLP Monitoring Authority.

At RPS, we conduct a wide range of testing to evaluate chemical properties of Agrochemicals in compliance with OECD guidelines. We follow internationally accepted methods and strict compliance to OECD principles of GLP

Our testing facilities are compliant via the GLP compliance monitoring program (MHRA) which enables our clients to submit validated data to their regulatory authority for review and approval of their product.

Only once approved, is the product safe to be used by people, animals (including food and animal feed) or released into the environment.

Our areas of expertise

  • Residue studies  
    RPS has extensive testing and analysis experience across a huge range of pesticides, herbicides, fungicides and other organic compounds in a wide variety of matrices. These include soil, water, crops, processed products and animal tissues. We can provide analytical support and complete management of multi-site studies on the following:

    • Method validation and ILV (Independent Lab Validation)
    • Freezer storage stability
    • Crop rotation, harvest and decline trials
    • Soil dissipation studies
    • Processing studies
  • Impurity profiling
    Our experts specialise in the non-routine testing of unknown materials and substances. Our forensic approach enables us to assist our clients and add-value to different stages of their enquiry/investigation.

    RPS provides analytical support for the analysis of unknown contaminants in various matrices and for various industries.

  • Active substance assay
    We provide analysis of pesticide formulations to confirm batch purity assay, and can also help in identifying unforeseen by-products and impurities resulting from manufacturing practices or leaching from packaging materials.

    RPS can set up methods to determine raw ingredients and formulated products, to provide external quality control and quality assurance, or to give you required validated methodology to implement in your facility. RPS can also provide confirmatory analysis of products, to resolve customer disputes such as claims of incorrect formulation or incorrect labelling.

The principles of Good Laboratory Practice

Good Laboratory Practice is about promoting the integrity and traceability of the data that is generated through laboratory analysis. We uphold its principles with regards to making the data we work with:

  • Attributable – As part of the GLP principles, we ensure that all data are attributable to the individuals who generated, modified or reviewed it. All records are contemporaneously and permanently documented to guarantee their integrity and traceability.

  • Complete – In addition to data and records generated within the GLP studies, supporting information such as equipment logs and reference material inventory are maintained as they contribute to the complete data set. This allows a full reconstruction of the activities that generated the results.

  • Accurate – all of the computer systems we use are validated to confirm they provide accurate results, and we perform 100% quality check (QC) of our data which are then subjected to auditing by quality assurance (QA). Our clients can be assured of the quality and validity of the reported results and conclusions.

  • Reliable – by being GLP compliant, we provide our clients reliable and defensible data for submitting to the relevant regulatory authorities. Under the mutual acceptance of data agreement, GLP compliant studies can be accepted between member countries of OECD, which currently has 38 member countries.

  • Available – on completion of a study, records are archived securely to protect them from alteration or loss, but these remain available and accessible through controlled systems. Our clients have peace of mind that their data can be readily retrieved to suit their needs.
