Sample Pretreatment and Separation (Analytical Chemistry by Open Learning) - Softcover

Raw samples taken for chemical analysis are unlikely to be tested in their original form. Virtually every analytical procedure calls for the sample to be pre-treated in some way. At the simplest level this may involve dissolution prior to some spectrophotometric reading; at its most complex it may involve conducting various complex extractions and derivative stages. In many analyses these stages may be more time consuming than the final analytical determination and may require a high degree of manipulative skill from the analyst. "Sample Pre-treatment" examines the major methods and techniques involved in preparing samples for analysis starting from a simple level and moving to the more complex. The final chapter gives details in a series of case studies of the applications of the subject matter.
