Some are very small, such as nanoparticles with dimensions of 1-100 nm and that might consist of just a few hundred atoms, and some are much larger. In this chapter we consider methods for determining the size of particles.

We can develop an analytical method for determining the concentration of lead in drinking water using any of the techniques mentioned in the previous section. The requirements of the analysis determine the best method and consideration is given the following criteria: accuracy, precision, sensitivity, selectivity, robustness, ruggedness, scale of operation, analysis time, availability of equipment, and cost.

How would you approach this problem? To provide a structure for answering this question let’s draw a distinction among four levels of analytical methodology: techniques, methods, procedures, and protocols.

In principle, it should be possible to derive the value of kA for any analytical method by considering the chemical and physical processes generating the signal. Unfortunately, such calculations are not feasible when we lack a sufficiently developed theoretical model of the physical processes, or are not useful because of nonideal chemical behavior.

There will be some small differences in the data because measurements are always a little imprecise and there might be some small differences in the way the experiment was done, but the data should be the same within the "error range."
