Safe handling of gases used in Atomic Absorption Spectroscopy

Atomic Absorption Spectroscopy requires two main gases, namely, air as oxidant and a fuel gas such as acetylene or nitrous oxide. Safe handling of gas supplies is of utmost importance for efficient operation of instrument and averting laboratory mishaps. The following practices are recommended for safe handling and storage of gas cylinders: Fasten gas cylinders securely […]

Time saving tips for analysis by AAS spectroscopy

AAS Spectroscopy provides cost-effective analysis of trace metals in a vast range of samples both natural and man-made such as geological samples, foods, plants, agricultural samples, soils, rocks, biological specimens, manufacturing streams, industrial effluents, pharmaceuticals and drinking water. The technique provides precise results and is a great time saver in comparison with the conventional gravimetric […]

A systematic approach to learn Atomic Absorption Spectroscopy

Trace metal studies are assuming great significance in diverse areas such as environment, drinking water, mining and mineralogy, oceanographic studies, soils, pharmaceuticals, foods, toys, forensic investigations, etc. The list is endless and presence or absence of trace metals is a factor that cannot be overlooked for evaluation of characteristics of materials or concerns regarding human […]

Microwave Sample Digestion – a great time and money saving technique for sample dissolution

Sample dissolution has been a challenge for the analytical chemist. Dissolution of samples such as minerals, ores, rocks, soils, ceramics, oxides and coal test your patience as digestions take several hours or even days to complete under harsh conditions involving highly corrosive acids and heat. Wet chemical digestions involve use of mineral acids conventionally in open […]

Choice of acid for dissolution of samples for trace metal analysis

Trace metal analysis by AAS or ICP techniques requires introduction of sample into the system in the liquid form. Solids or powders need to be dissolved using acids so that the metals of interest are extracted in the liquid phase. The objectives of sample digestion are: Conversion of metals to soluble salts Removal of matrix interference […]

What is the Benefit of using Blazed Gratings in AAS Spectrometers?

A grating is an optical element in a monochromator that disperses the broadband light beam into distinct wavelengths. The desired wavelength is selected by adjusting the exit slit width of the monochromator. The angle of dispersion of the grating depends on the number of lines on the grating. Larger the number of lines (usually 1200 lines/mm […]
