Unformatted text preview: 2. All sampling steps are needed to convert a representative bulk sample into a form suitable for chemical analysis. 3. The bulk sample is taken from the lot. From this bulk sample, one obtains the smaller laboratory sample. 4. The laboratory sample is the same consistency and representation of the bulk sample. From this, one derives an aliquot which has been converted into a form suitable for chemical analysis (such as being ground into a powder). 5. In choosing a representative sample, the sample must replicate the populations chemical composition, and relative sizes of the different layers must be made and included in the calculations....
