ABSTRACT
This chapter will address the application of X-ray fluorescence spectrometry (XRF) in the context of an aquatic sediment sampling program where total as opposed to acid-extractable analyses are required. The technique will be described in general terms, emphasizing those aspects common to academic and commercial settings. These include the client’s need for accuracy, speed, and economy. The decision to choose XRF for a specific analytical task is usually based on some balance between these often conflicting obligations.
