2:6 Planning the project

Construc)ng the Plan

A2er the problem is defined, the planning process can begin. Analy)cal text books explain that you must consider the sample collec)on, sample storage, sample prepara)on, measurement, and repor)ng, along with any QA/QC requirements. With so many considera)ons, where should you start?

Start by examining the following basic informa)on: • The analyte(s) of interest.

• The required detec)on limit(s). • The uncertainty requirement(s).

• The chemical composi)on (matrix) of the sample. • The quan)ty, availability, and history of the sample.

2:7 Planning the project

Constructing the Plan (cont.)

Much of the previous list can be determined based on information gathered while defining the problem. In most cases, analytical resources are available in-house to address the problem.

For example: • The basic information listed previously is sufficient to determine whether publications or information is available in your reference library. Always start with a search of the literature. • The identity and detection limit requirement of each analyte indicates the analyte measurement technique(s) required and the amount of sample required. • The uncertainty requirement indicates the number of measurements, assuming there is sufficient sample available. • The chemical composition of the sample, together with the identity of the analyte(s), indicates possible sample preparation routes.
