Sample preparation refers to a family of solid/liquid handling techniques to extract or to enrich analytes from sample matrices into the final analyte solution. While SP techniques are well documented, few references address the specific requirements for drug product preparations, which tend to use the simple "dilute and shoot" approach. More elaborate SP is often needed for complex sample ...

Note 3: Discussions on moisture content are common in many rock testing standards but professional judgement will be needed to both handle and report this issue. For example, when obtaining the samples or preparing the specimens, water or some other cooling agent may be required or used. Therefore, the moisture in the specimen or samples may not be what it was in situ; this applies to both ...

Sample preparation includes separation of coarse material, homogenization and drying, and it is the first crucial step of sediment analysis. Nuclear and related analytical techniques such as gamma ray spectrometry is used for radionuclides determination while neutron activation analysis (NAA) and X ray fluorescence spectrometry (XRF) are used for elemental characterization. Although these are ...

Proper sample preparation is essential to getting highly quality XRD data. If you do not put in the effort to properly prepare your sample you can introduce errors that make phase identifiion difficult to impossible and estimates of abundances and crystallinity erroneous. Ideally, you need to achieve three conditions in order to have good data: Total randomness of crystallite .

The rock sample preparation lab therefore hosts many tools. In the rock sample preparation lab, rock samples collected in the field may be processed and prepared prior to further analysis. It is often necessary to reduce the size of the sample, some analyses require a smooth, polished surface, or it may be necessary to grind the rock to a fine powder.
