Ease of Instrumentation...more on it

But, can an instrument be created so simple that the analyst does not even need to think? The real question is are the samples so similar that an instrument (or test) can be designed well suited for all without any adaptation. The answer, for environmental testing, is no! It is not possible to create methodology that will be suitable for all samples because the variety of environmental samples varies too much. Even water, which one might think is all the same, has extreme varieties in its matrix.
