One challenge with ICP-OES sample preparation is the analysis of samples containing toxic elements such as arsenic, mercury, antinomy and selenium. These samples are common in environmental, biological, and food samples; furthermore, regulations require lower limits of detection for toxic elements year after year to ensure that their contamination levels are maintained at an absolute minimum.

Sample preparation Proper sample preparation is one of the most important requirements in the analysis of powder samples by X-ray diffraction . This statement is especially true for soils and clays that contain finely divided colloids, which are poor reflectors of x-rays, as well as other types of materials such as iron oxide coatings and organic materials that make characterization by XRD more difficult.

In this module several aspects of sample preparation will be considered. The focus of the first section is directed at liquid-liquid extraction (LLE) and solid phase extraction (SPE). Though other aspects of sample preparation such as digestion, precipitation, and pre-concentration are critical to a successful analysis, they are typically specific for the sample and analyte to be determined.
