Elemental Analysis

Elemental analysis is a process where a sample of the blood or tissue material is analyzed for the elemental and sometimes isotopic composition. It can be divided into two types: qualitative and quantitative. Elemental analysis can be used to characterize and discriminate or associate questioned and known samples of paint, glass, soil, and bone, and to determine purity of compounds. The typically analysed elements are carbon (C), hydrogen (H), nitrogen (N) and sulfur (S), rarely also oxygen (O) is measured. The analytical methods include: Kjeldahl Method, Thermal-Optical Analysis (TOA), X-Ray Fluorescence (XRF) and so on.
