Analytical chemistry is a rapidly growing science and its scope is expanding by the day due to development of new materials, growing consumer demands and lowering of standards on toxics in environmental samples and items of human consumption. 125 job profiles for an analytical chemist outlines some vital areas which hold promise for growth and applications of analytical testing.
Instrumental techniques hold great promise in advancement of analytical chemistry. Developments in electronics, miniaturization and automation have contributed greatly to accuracy, precision and high throughput in laboratories across the world. However, classical techniques have continued to hold ground and are still popular in school, college and industrial laboratories .It is common to see a wet chemistry section in even in most advanced and well equipped laboratories. The present article examines the main reasons that are responsible for the continued interest in classical analysis
Easy to Comprehend
Classical analysis techniques are easily understood and adapt by all those having an understanding of basic concepts of chemistry and analysis
Help in understanding basic concepts and principles of analysis
Anyone involved in classical analysis requires clarity on basic concepts of chemical analysis such as acid-based neutralizations, complexation, solubility, concentration units and inter-conversions, equilibrium constants and laboratory practices such as phase separations, weighing and serial dilutions. Classical analysis techniques help build a strong foundation of basic concepts of chemical analysis.
Classical techniques appear to be cumbersome and time-consuming as they involve several stages. However, as sophisticated equipment along with associated environmental control costs offer greater laboratory throughputs the initial and operational costs can be a limiting factor for medium-sized laboratories.
It is important to realize that you have to be a good chemist first before you adapt yourself to sophisticated instrumental analysis. Operation of such sophisticated instruments fascinates all of us but bear in mind that even the most sophisticated instrument will provide reliable results only if you have exercised your basic knowledge of chemistry and skills in extraction and preparation of sample solutions.
