Sample Preparation and Purification

Abstract

Preparation of the sample is of vital importance before undertaking complex separation and purification procedures. A suitable sample pretreatment can save much time and effort in subsequent steps and make isolation considerably easier. Whether the probe is of biological origin with contaminating proteins, or from industrial processes and contains residual catalyst, or from a plant source with interfering matrix elements, a simple preliminary step is often useful to remove most of the undesired material.
