Organic geochemical analysis sample requirements

Many techniques employed for elemental analysis require the conversion of the sample matrix into a solution form. The selection of an appropriate treatment for sample dissolution depends on the nature of the sample, and different approaches are required for predominantly inorganic and predominantly organic matrices. Geological, geochemical, and soil samples generally contain silicate, metal oxides, carbonates, and, in many cases, organic matter. Such samples must be dried and ground to a fine powder to...
