Tips to ensure high uptime of your Atomic Absorption Spectrometer

Preventive maintenance is the key to ensure high uptime of your Atomic Absorption Spectrometer. It is a rugged instrument which can provide you high quality results for years together provided its maintenance schedules are followed religiously. It is a good practice to make general visual inspection of the system before starting your day’s work Such […]

Vapour Generation – an alternative technique in Atomic Absorption Spectroscopy

Trace metals are routinely analysed in ppm and ppb or even sub- ppb levels using conventional flame and graphite furnace Atomic Absorption Spectroscopy techniques. The vapour generation techniques offer an alternative for low-level determinations. Cold vapour technique for Mercury analysis Mercury is an element which has assumed global concern due to its high toxicity. It […]

Safe handling of Organic Solvents in Atomic Absorption spectroscopy

Water is the safest solvent that you can be use in Atomic Absorption Spectroscopy but many applications require use of organic solvents. Handling and usage of organic solvents requires strict adherence to safe practices to prevent laboratory mishaps. Organic solvents can pose safety hazards mainly due to two main factors, namely, toxicity and flammability. Measures […]

Organic Solvents in Atomic Absorption Spectroscopy

Water is a universal solvent and is used in a majority of atomic absorption spectroscopic applications. Benefits of using water as solvent: Non-Toxic so no toxic fumes on ignition Non-flammable Constant physical parameters such as viscosity, density and specific Heat Apart from Its Safe Use constant physical parameters permit optimum use and design of nebulizers, […]

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 […]
