To achieve the accurate, reliable XRF data demanded in today's business and regulatory environments, it is essential that good quality samples are delivered to the instrument for measurement. Samples of insufficient quality can have a large negative impact on the results. The key requirements of sample preparation are that samples should be representative of the source material and be homogeneous. Additionally, the elemental composition of the sample should not be altered before or during the preparation process. Provided these three conditions are met, a wide variety of sample types can be analyzed using XRF. Common sample forms include fine powders, granules, solids, liquids, chips and drillings.
