Sample destruction for classical elemental analysis

Trends in element analysis are multi-element (survey) analysis, lower concentration levels, micro/local element analysis and speciation (coupling with chromatography). An overview of the determination of elements in polymeric materials is available [7], Reviews on sample preparation for trace analysis are given in refs [8-10]. Quality assurance of analytical data in routine elemental analysis has been discussed [11], Organic analysis is obviously much more requested in relation to polymer/additive matrices than elemental analysis. [Pg.591]

Destructive solid sample preparation methods, such as digestion and mineralisation, are well known as they have been around for some time they are relatively cheap and well documented [13-15]. Decomposition of a substance or a mixture of substances does not refer so much to the dissolution, but rather to the conversion of slightly soluble substances into acid- or water-soluble (ionogenic) compounds (chemical dissolution). [Pg.591]

This involves a chemical change. It is required that any decomposition procedure should alter the original environment of the sample into a digest, i.e. a solution in which the analyte is distributed homogeneously. More specific conditions set to a decomposition technique are [4]  [Pg.591]

Decomposition and dissolution processes are generally subject to fairly large sources of error, namely  [Pg.591]

The analyst s requirements to digestion procedures are given in Table 8.3. [Pg.591]
