Introduce About Analytical chemistry

Chem-Eng.21

Analytical chemistry is the study of the separation identification, and quantification of the chemical components of natural and artificial materials. Analytical Chemistry is a science that is very important in the world of chemistry or laboratory. with this knowledge we can determine the size or concentration of a solution, through several methods of work. and in chemical analysis is no miraculous methods of work, namely classis and modern methods. and at times will be discussed in detail. Chemistry is the study of matter, including its composition and structure, its physical properties, and its reactivity. There are many ways to study chemistry, but, we traditionally divide it into five fields: organic chemistry, inorganic chemistry, biochemistry, physical chemistry, and analytical chemistry. Although this division is historical and, perhaps, arbitrary—as witnessed by current interest in interdisciplinary areas such as bioanalytical chemistry and organometallic chemistry—these five fields remain the simplest division spanning the discipline of chemistry. Analytical is very important for A Engineering!

1     1. HISTORY OF ANALYTICAL CHEMISTRY

• Classical methods: early years (separation of analytes) by precipitation, extraction or distilation.
• Qualitative: recognized by color, boiling point, solubility, taste.
• Quantitative: gravimetric or titrimetric measurements.
• Instrumental methods: Newer, faster, more efficient.
• Physical properties of analytes: conductivity, electrode potential, light emission absorption, mass to charge ratio and others.

2.      2. CLASSIFICAION OF MODERN ANALYTICAL METHODS

 \

• Gravimetric Methods determine the mass of the analyte or some compound chemically related to it.
• Electroanalytical Methods involve the measurement of such electrical properties as voltage, current, resistance, and quantity of electrical charge. 
• Spectroscopic Methods are based on the measurement of the interaction between electromagnetic radiation and analyte atoms or molecules, or the production of such radiation by analytes
• Miscellaneous Methods include the measurement of such quantities as mass-to-charge ratio, rate of radioactive decay, heat of reaction, rate of reaction, sample thermal conductivity, optical activity, and refractive index.
