Comparative evaluation of sample digestion techniques for Atomic Absorption Spectroscopy

Trace metals analysis by Atomic Absorption Spectroscopy requires the introduction of the sample into the system as a homogeneous liquid. It is necessary to digest solids for complete extraction of analyte(s) of interest into the solution. Commonly used practices are: Acid digestion Fusion Ashing The technique adopted should be safe, reproducible and afford to save […]

How Knowledge of Atomic Absorption Spectroscopy will contribute to my career growth?

Awareness and need for testing of materials existed even in ancient times and has grown keeping its pace with the growth of human civilization. Today you cannot imagine any man-made product be it a machine tool, glass decorative item, food product, pharmaceutical, plastic ware or for that matter any other product which has not undergone […]

Influence of Burner Head Geometry on Flame characteristics in AAS analysis

The flame of the atomic absorption spectrometer is comparable to the absorption cell in an optical spectrometer. Atoms in the ground state serve as the light absorbing species. The absorption signal is dependent on flame length and number of absorbing ground state atoms in the light path. Role of AAS Burner has been briefly discussed […]

Air or Nitrous oxide – which is the right oxidant gas for Flame Atomic Absorption Spectroscopy analysis?

Flame AAtomic Absorption Spectroscopy requires an oxidant gas in addition to fuel gas to support combustion.The two gases which are commonly used as oxidants are air and nitrous oxide. Have you ever wondered as to what considerations help you decide between the two gases and why pure oxygen is never recommended. Read on the  to get answers […]
