On May 14th 2007 we’ll celebrate 135th birth anniversary of an outstanding Russian chemist Mikhail Semyonovich Tsvet who discovered and, for the first time, applied essentially new method of analysis – chromatography. Nowadays, chromatography has become an indispensable method of separation and analysis of complex substances. With its help, scientists were able to figure out complex structures and compositions of protein compounds, isolate most of transuranium elements of periodic table, separate and purify antibiotics, vitamins, alkaloid and hormones. Chromatographic phenomena could be found in many natural geochemical processes such as soil formation and most of the ore deposits. And that’s why I am dedicating this blog entirely to chromatography!
