Prevention of contamination in trace metal analysis laboratories

Today advanced sophisticated analysis techniques are capable of providing trace metal analysis in ppm, ppb or even ppt levels. The most popular techniques are Atomic Absorption Spectroscopy, ICP – MS and ICP – OES. Determinations at low levels can be reliable only if adequate precautions are taken at different stages of analysis such as sampling, […]

Tips for the maintenance of the Flame Assembly of AAS

The flame assembly can be considered as the heart of the AAS. It comprises of three main comments : the nebulizer, spray chamber and the burner head. Regular upkeep and maintenance of the component parts can provide a long service life span of the instrument, minimum breakdowns and a higher reliability on results. The article […]

Sampling essentials for Water analysis using Atomic Absorption Spectroscopy

Analysis of trace metals in water is an important application of Atomic Absorption Spectroscopy. Trace metals in water play a crucial role as majority of metals act as essential nutrients at low concentrations but excess levels can have harmful consequences. It is imperative to test for concentration levels of trace metals in water before it […]

Wear Metal Analysis in Used Oils- A potential application area of Atomic Absorption Spectroscopy

Engines constitute an important power generation source in road transport vehicles, aviation and small scale power generation for industrial and agricultural applications. The efficiency of running of different types of engines depends on their regular maintenance and monitoring of condition of component parts. It is neither practical nor desirable to disassemble an engine every time […]

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 […]

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 […]

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 […]

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, […]
