Liquid Chromatography: Introduction to Method Development

Abstract

The development of fit-for-purpose analytical methods is an essential component of chemical metrology. This presentation will provide guidance on approaches for establishing robust analytical methods, particularly with applications to liquid chromatography. Because nearly every measurement need represents unique challenges, this guidance is necessarily general in scope. A stepwise process is outlined for the development and implementation of an analytical procedure. The presentation includes the following topics that are not limited to liquid chromatography, but are generally applicable to most instrumental methods. 1. Objectives of the analysis. Depending on the goals, the details of the method used will vary significantly. 2. Sample Properties. The physical and chemical properties of both the sample (matrix) and the analytes are central to the development of analytical methods. 3. Choice of instrumental method 4. Sample processing 5. Basis for quantitation Details specific to the development of methods based on liquid chromatography are provided in the second half of the presentation. Recommendations are made concerning initial column selection and the choice of isocratic or gradient elution approaches. Different decisions may be required that depend on the measurement challenge. Alternatives are discussed that can be explored when measurement goals are not initially achieved.
