ALL scientific workers who have had occasion to employ colour-sensitive photographic plates during the last few years will probably have wished at some time to learn some details as to the specially ...

Flame Atomic Absorption Spectroscopy (FAAS) is a very popular analytical technique that has been employed by researchers for the elemental analysis of trace metals in a variety of samples. How does it ...

Infrared spectroscopy (IRS) is a technique used to analyze individual substances in isolation or a mixture, using their spectral information. IRS is based on the measurement of the wavelength and ...
