Introduction
Preparation of the sample before it is added to the system can be critical. Over half
the problems encountered when measuring a sample are caused by poor sample
preparation. If the sample is sticking together, dissolving or floating on the surface,
or if it is not a representative sample, the result will be incorrect.
There are many techniques available to ensure that the sample is prepared success-
fully. Once a suitable dispersion technique is found for the sample, standardise the
procedure (using an SOP) so that comparisons can be made between samples.
This chapter gives information on:
 Sample preparation flow chart – summarises the process.
 Representative sampling.
 Considerations for dry samples.
 Considerations for wet samples.
 Symptoms of poor sample preparation.
