Thin layer chromatography
The technique of Thin Layer Chromatography (TLC) is normally used as an analytical method to follow the progress of a reaction, to analyse mixtures or to establish conditions for a preparative separation of compounds using column chromatography. The stationary phase (often silica) is coated on plastic or aluminium plates. The ...

On This Day – Jul 07 : Rocket apparatus fueled with solid 'explosive material'
The first of these rockets was successfully launched on 16th March 1926 by the American scientist and his colleagues in Auburn, Massachusetts. It was fuelled by liquid oxygen (O2) and gasoline, and reached a height of 12.5 metres.

Column chromatography
The separation of mixtures produced in chemical reactions is often carried out by passing the mixture through a stationary phase of silica held in a column. Solvents move compounds at different rates through the silica allowing them to be separated into fractions by collecting the emerging solvent. This can ...
