ABSTRACT
It is important to provide your customer with reliable results that are fit for purpose. As forensic scientists, we look to do this by performing instrument qualifications (calibrations against verified reference materials) and method validations (using verified reference standards), and by ensuring that we apply rigorous system suitability (see Chapter 7) and quality procedures into our methodologies. In relation to HPLC, qualification relates to an assessment of the instrumentation (pump, injector, column compartment, detector) that is used to determine the measured result, whereas validation relates to the applications and methods that are used to generate the results.
