This requires collection of the sample on a methyl-cellulose ester ( MCE ) filter and acid digestion of the collection media in the laboratory followed by measuring metal concentration though an atomic absorption ( or emission ) spectrophotometery.

It is also typically used in the digestion process of turbid water samples, sludge samples, solid samples as well as other types of unique samples which require elemental analysis via ICP-MS, ICP-OES, ICP-AES, GFAA and flame atomic absorption spectroscopy.

Atomic absorption spectroscopy was first used as an analytical technique, and the underlying principles were established in the second half of the 19th century by Robert Wilhelm Bunsen and Gustav Robert Kirchhoff, both professors at the University of Heidelberg, Germany.

In 1970, Geoffrey Frew donated a substantial sum to the Australian Academy of Science'in recognition of the successful commercial development of atomic absorption spectrochemical analysis, which had been originated by Dr A . Walsh of the CSIRO Division of Chemical Physics in 1954 '.

Depending on the level of purity needed, detection of these contaminants can range from simple conductivity ( electrolytic ) readings to sophisticated instrumentation such as ion chromatography ( IC ), atomic absorption spectroscopy ( AA ) and inductively coupled plasma mass spectrometry ( ICP-MS ).

Modern phytotherapy may use traditional methods of assessment of herbal drug quality, but more typically relies on modern processes like high-performance liquid chromatography ( HPLC ), ( gas chromatography ), UV / VIS ( Ultraviolet / Visible spectrophotometry ) or AA ( atomic absorption spectroscopy ).

The institute is equipped with state of the art facilities among Animal housing, In vivo-imaging, Automated electrophoresis, Flow cytometry, DNA Microarray, Liquid chromatography mass spectrometry, Atomic absorption spectroscopy, Matrix-assisted laser desorption / ionization, Scanning electron microscope, Confocal laser scanning microscopy, Transmission electron microscopy, DNA sequencers, Cryogenic equipment, thermal cyclers etc.

Recognized mineralized zones were assayed using conventional fire assay with an atomic absorption or gravimetric finish, and at the end of the program, sample composites ( made by combining reject samples from multiple drill holes previously analyzed by conventional fire assay ) were made and sent to Lakefield Research for metallurgical testing.

:If the atomic absorption spectroscopy shows a small amount of iron, why do you think there isn't any ? ( I ask because, whatever other method you used that shows no iron, that might be the method giving the wrong answer . ) talk ) 14 : 04, 6 March 2009 ( UTC)

Notable developments by CSIRO have included the invention of atomic absorption spectroscopy, essential components of WiFi technology, development of the first commercially successful polymer banknote, the invention of the insect repellent in Aerogard and the introduction of a series of biological controls into Australia, such as the introduction of myxomatosis and rabbit calicivirus for the control of rabbit populations.
