Chromatography - Paper Chromatography
We
have seen in our previous post that any chromatographic technique consists of
a stationary phase and a mobile phase. In the case of paper chromatography,
which is one of the type of plane chromatography, paper acts as a stationary
phase while the mobile ...

Spectrophotometry - Atomic Absorption Spectrophotometry
Atomic absorption spectroscopy (AAS) is similar to flame photometry with the difference that it measures the absorption of a beam of monochromatic light by the atoms in the
flame. This technique was first introduced by Alan Walsh in Australia in 1954. We wi...

Spectrophotometry - Flame Photometry
Flame spectrophotometry is a technique in which the
intensity of the radiations emitted by a chemical into the flame is
determined.  This basic concept of working of flame spectrometer is that, a flame,
through its heat, can raise the atoms from a lower ene...

Spectrophotometry - Luminometry
Till now, we have seen various posts on UV-visible
spectrophotometry, IR-spectrophotometry and spectrofluorimetry. Now, we will
have a look at the next type of spectrophotometry which is luminometry.  As the name suggests, this type of spectrophotometry is
...
