作者首先叙述了分析化学的源起,认为这门科学与人类文明文化,如青铜、黄铜冶炼、酿酒等大有关系。继出现东、西方的丹金术、欧洲中世纪的大试金术。后者可称为现代分析化学的前驱。适十七八世纪现代化学之兴起,分析化学起了主要作用。嗣后重量法、容量法、比色法、分光光度法、发射光谱法、极谱法、质谱法、层析法等等相继出现。这些方法可分为两大类——即化学法和仪器法。二者各有其优缺点;需要相辅相成,而决不是对立、排挤。另一方面,常量法之后又出现微量法和痕量分析。最后为分析化学在我国健康成长提出一些看法和意见。
The author first described the origins of analytical chemistry, that this science and culture of human civilization, such as bronze, brass smelting, brewing and so on. Following the emergence of the East and West Danjin, Europe’s Middle Ages gold test. The latter can be called a precursor to modern analytical chemistry. With the rise of modern chemistry in the seventeenth and eighth centuries, analytical chemistry played a major role. Subsequent gravimetric method, volumetric method, colorimetry, spectrophotometry, emission spectroscopy, polarography, mass spectrometry, chromatography and so on have appeared. These methods fall into two broad categories - chemical and instrumental. Both have their own advantages and disadvantages; need to complement each other, but by no means opposites, crowding out. On the other hand, trace method and trace analysis appear after the constant method. Finally, some opinions and opinions on the development of analytical chemistry in our country are put forward.
