The AL-204 has been specially designed to quickly and accurately determine the concentration of aluminium in slags. Via the analysis of the gases resulting from the attack to the sample with Sodium Hydroxide (NaOH) you can quickly obtain – in just ten minutes – and accurately – a precision of >99% - the percentage of aluminium contained in the sample.

Aluminum Metal Analyzer

2. AL 204 Aluminum Metal Analyzer
In comparison to the traditional method with which this type of analysis was performed, the AL 204
represents a qualitative leap in many ways:
• Time: compared to the traditional method, from hours to minutes - 10
minutes per analysis -.
• Accuracy: you can obtain certainty on the aluminum content of your
sample with an accuracy of less than 1%.
• Comfort: The entire procedure is performed directly in your computer,
collecting the results in a specially designed software from which you
can perform statistical analysis, averages, standard deviation. You can
see the results in graphics directly on the screen software to make quick
comparisons.
• Safety: the handling of corrosive liquids is reduced to a minimum.
• Versatility: in addition to managing the data directly in your specific software, the results are
exportable to settings such as Access or Excel.
The AL 204 equipment has been specially designed for
fast and accurate determination of the concentration of
aluminum in metal slags. Through the analysis of gases
resulting from the attack of the sample with sodium
hydroxide (NaOH) can be obtained quickly - in just 10
minutes - and accurate - accuracy >99% - the percentage
of aluminum content in the sample.

3. Principio
The H2
released from the re-
action, kept sealed under a
constant volume and stable
temperature conditions, will
generate a pressure increase
proportional to the percent-
age of metallic aluminium in
the sample.

4. Working method
Place the weighed sample in a crucible and introduce a stirrer, insert all into the
analyzer and close the head
Automatically - by a peristaltic pump - the analyzer will dispense an excess of reagent
A to the sample, to start up the reaction.
At the same time, the crucible heating system and the stirring system will be swuitched
on- these will remain operative until the end of the analysis.
The end of the analysis will be determined by a preset analysis time or else
automatically - once the pressure may remain stable for a certain period of
time.
The Unit will compensate the temperature - automatically - to determine the
result in an accurate manner.
