Thermo Fisher Scientific has launched an improved method that provides ultra-fast analyses of inclusions in aluminium using optical emission spectroscopy (OES).

The method, which utilises the Thermo Scientific Spark-Dat option, enhances the capabilities of the Thermo Scientific ARL 4460 metals analyser, offering a faster and more accurate alternative to existing methods of characterising inclusions in aluminium, according to the company.

Inclusions can affect the properties of aluminium, including mechanical strength, gas porosity, surface quality and fluidity.

The Spark-Dat enables the ultra-fast counting of inclusions and identification of their type in a few seconds, making it highly effective for controlling inclusions during aluminium production.

When combining the inclusion analysis with the standard analysis in concentration, only a few seconds of additional time is necessary.

The company claims that this ability to obtain elemental analysis information and inclusion contents with a single OES instrument greatly reduces investment cost.

The inclusion analysis is carried out under the same conditions as the regular elemental analysis.

The Spark-Dat option on the Thermo Scientific ARL 4460 metals analyser increases the versatility of the spectrometer.

From routine use to research, the Spark-Dat is claimed to provide a quick, simple and cost-effective solution for inclusion analysis in the aluminium industry.

An application note has been developed to demonstrate the benefits of the Spark-Dat option.
