The key topics section groups information on topics which are considered to be of critical importance in delivering good quality analytical measurements. This section is an excellent starting point for those wishing to increase their understanding of key knowledge areas such as method validation and measurement uncertainty.

  • Mass Spectrometry

    An introduction to mass spectrometry and examples of its application.

  • Bioanalysis

    An introduction to some of the key techniques used in bioanalysis.

  • Measurement Uncertainty

    An introduction to measurement uncertainty and how it can be evaluated.

  • Method Validation

    An introduction to the importance of and the principles of validation of analytical methods.

  • Proficiency Testing

    Proficiency Testing is a widely-used quality tool for laboratories to compare the values of their measurements with peer laboratories.

  • Traceability

    Traceability is a key requirement for laboratories accredited to ISO 17025. But what is traceability and how is it implemented?

  • Reference Materials

    Reference materials are one of the cornerstones in producing reliable chemical measurements.

  • The VAM Principles

    The six VAM principles enable organisations to implement best practice and make valid measurements.

  • Case Studies

    A set of case studies illustrating key outputs from the VAM programme.
