AAS: Instruments

Since its development in the 1950’s the Atomic Absorption Spectrometer (AAS) has evolved into an accurate and reliable analytical tool used extensively in today’s modern laboratory.

AAS is an analytical procedure for the Qualitative and Quantitative determination of chemical elements in a sample. 

The technique is based on the Lambert-beer principle which states that the absorbance of a solution (A) is directly proportional to its path length (I) and its concentration (C) when the wavelength of incidence light remains fixed.
This is summarized in the following equation, where (ε) is the molar absorbtivity. 
A= εIc
We offer a range of instrumentation designed to meet the requirements of all industry sectors including Agricultural, Clinical, Environmental, Food, Metal, Mining and Materials, Petrochemical and Pharmaceutical.

There are three main techniques for AAS analysis (Flame Analysis, Graphite Analysis & Hydride Analysis) each having their strengths and weaknesses depending on the type of analysis required.

There are a number of factors to consider when deciding which technique will suit the application.
For example: 
- Detection limits Speed of analysis Sample volume
- Equipment cost l Element suitability
- Clean area
- Running costs Working range
- Automation
- Sample matrix
- Precision of results
- Available space required
- Method development
