12 LABORATORY SAMPLE PREPARATION 12.1 Introduction On first impression sample preparation may seem the most routine aspect of an analytical protocol. However it is critical that analysts realize and remember that a measurement is only as good as the sample preparation that has preceded it. If an aliquant taken for analysis does not
