Sample collection and preparation

Abstract

Sample collection and preparation are inextricably linked to the practice of radioanalytical chemistry, despite the fact that two separate groups will perform these activities. Ideally, the radioanalytical chemist is part of the team that plans the sampling effort and prepares the quality assurance project plan (see Section 11.1). Such participation in the planning phase benefits the entire analytical process. The radioanalytical chemist can tailor the analytical approach to both the sample media and the radionuclides in the media. Information on the purposes for which the laboratory produces data can enable the radioanalytical chemist to devise laboratory practices to match required detection sensitivity, sample submission rate, and reporting style. On the other hand, the analyst can describe the capabilities and limits of the laboratory to the planning group. Such participation in the planning process can prepare a cohesive sampling and laboratory effort that produces defensible results for the client. © 2007 Springer.
