Basic Training 4th Annual ICP Conference

2:2 Planning the project

Overview (cont.)

This section assumes that the chemist will be analyzing samples that fall into one or more of the previous categories. Before the planning process can begin, the analyst must examine the following:

• The need for sampling and sub-sampling • Reagent quality • Sample preparation • Measurement • QA/QC • Reporting requirements

2:3 Planning the project

Defining the Problem

A discussion between the initiator and the analyst must occur, where questions are asked by both parties. The intent is to define the exact nature of the problem, why analytical work is needed, and how the results will be used following the completion of the project. Method validation requirements should also be addressed. These requirements can include either the availability of a certified reference material, or that of another validated technique -- one that is based largely on different principles. The problem's definition is further refined by asking other questions: What is it that you want to accomplish? What is the purpose? What is the current situation or state of affairs? What is taking place that you need to understand, prevent, or improve? What decisions will be made based upon the data?

When the answers to these questions have been determined, the analyst is in a position to begin planning the analytical process.
