Flame Atomic Absorption Spectroscopy


The ASU operates an Agilent, FS (Fast Sequential) 280 instrument. This is a sophisticated research grade atomic absorption spectrometer and offers the capability of performing routine flame based analysis of up to eight elements with a fully automated system at speeds comparable to an ICP-OES spectrometer.


Fast Sequential AA can cut analysis time and reduce sample consumption compared to conventional AA by measuring all elements in a sample before moving to the next sample.


Multiple elements are determined in rapid sequence allowing internal standard corrections to be applied on-line to correct for long term drift or sample preparation errors.

For Atomic Absorption spectrometry, 'flame mode' is the most common way to get atoms into a ground atomic state where they can be measured.


The flame in AA can be generated using a number of different combinations of fuel and oxidant. The most common pairing is air (as an oxidant, supplied from a compressor or pressurized tank) and acetylene (as the fuel).




Sample Introduction Pump System (SIPS)

Our FS280 instrument comes with a SIPS10 standard preparation and sample dilution feature.

The SIPS feature removes tedious standard preparation steps and effectively extends the linear range of the instrument to reduce required sample dilutions.
