  • Analytical chemistry is the study of the separation, identification, and quantification of the chemical components of natural and artificial materials.[1] Qualitative analysis gives an indication of the identity of the chemical species in the sample and quantitative analysis determines the amount of one or more of these components. The separation of components is often performed prior to analysis

  • At the beginning of the 19th century the description of matter attained, what one would call today, a scientific basis. Dalton1 supported the atomic theory with experiments permitting the development of modern chemistry. The book “A New System of Chemical Philosophy,” describes this new approach. In Fig. 1.1, an excerpt is displayed. Chapters I and II give a summary of the contemporary understanding of nature by analyzing heat and mass, the two basic building-blocks of any material. Chapter I displays the theory of the caloric as it was generally...

  • Introduction: The chemical warfare agents well known count only about 30 kinds of compounds, such as sarin, soman, tabun, VX, mustard gas, lewisite and others. When unknown toxic substances should be analyzed upon the occurrence of chemical terrorism, much more kinds of poisons and related compounds become the objects of analysis. In the Chemical Weapons Convention (CWC)a, 120 thousand compoundsb, including typical chemical warfare agents, their related compounds, precursors and decomposition products, are being listed to be controlled.

  • Chemical substances (also called pure substances) may well be defined as "any material with a definite chemical composition" in an introductory general chemistry textbook.[2] According to this definition a chemical substance can either be a pure chemical element or a pure chemical compound. But, there are exceptions to this definition; a pure substance can also be defined as a form of matter that has both definite composition and distinct properties.[3] The chemical substance index published by CAS also includes several alloys of uncertain composition.
