In recent years , research in analytical chemistry has concernedmainly on the development and application of physical andphysicochemical analytical methods , instrumental analysis ,which in their speed and sensitivity have far surpassed theclassic methods of gravimetric , and even volumetric analysis. Almost all reseachers in natural science field have beensupported by analytical data in 20th century. Analytical methodshave been improved by the progress of the analytical instrumentsbased on the physical measurement supported by the electronics.Many Nobel prizes of chemistry and physics were given to theinvestigations of new method of analytical measurement. Thegoal of analytical measurement has been always how to get highsensitivity and selectivity. Now in analysis the final detection is carried out almostinstrumentally. Students have to learn many informations aboutinstrumental analysis. But in the case of analyzing real samplesthe most important problem is how to treat them before theinstrumental measurement, that is, decomposition of sample,separation from matrix, preconcentration etc. Instrumentalanalysis is based on to compare the signal from the sample withthat from standard. Recently standard solutions for instrumentalanalysis are easy to get on the market. But in the basic educationin analytical chemistry it is important to teach how to get theaccurate amount of a particular substance in a sample absolutelyby weighing the precipitation or measuring the volume of thesolution. Gravimetric analysis and volumetric analysis areconsidered to be fundamental still now. Most students studyingchemistry in universities specialize in other field than analyticalchemistry. But they will discuss their research results on thebasis of the analytical data in the future. Analytical data have tobe always correct. Incorrect data will lead the conclusion to thewrong way. I would like to emphasize that the basic education inanalytical chemistry for future generations of chemists is to teachhow to get the accurate analytical data. For this purpose thedesirable curriculum of analytical chemistry is considered to becomposed of chemical analysis, separation chemistry andinstrumental analysis, including experiments to learn theanalytical methods and techniques.
