WebE. Paper Chromatography. Chromatography is used to separate mixtures of substances into their components. All forms of chromatography work on the same principle. They all have a stationary phase (a solid, or a liquid supported on a solid) and a mobile phase (a liquid or a gas). The mobile phase flows through the stationary phase and carries the ...

WebJan 31, 2024 · The invention of what we now know as chromatography is typically attributed to Russian botanist Mikhail Tsvet. He developed the technique in the early 1900s and used it to separate plant pigments. It wasn’t until the 1930s and 1940s that chromatography methods were further developed, making the technology more widely applicable. WebIn paper chromatography the frequently occurring elongated spots make it difficult to estimate the true mass centres of the different substances. The more circular spots on thin-layer chromatograms give less difficulty. Band-wise application gives chromatographic bands after resolution, the quantitation of which is . simpler still.
