2029 Aluminum Analyzer

From Metrohm Process Analytics

Aluminum is the most abundant metallic element of the Earth’s crust (8%) and is a very reactive base metal. It has low density, high electrical and thermal conductivities and high corrosion resistance. Because of these remarkable characteristics, the metal is commonly used as a building structure material in construction, aircraft and automobile industries. It is also used in the production of metal alloys for semiconductors and as a coagulant in potable water plants to remove organic matter, turbity and microorganism.

Because of its role in many different production processes, it is of vital importance to closely monitor the concentration. The 2029 Aluminum Process Analyzer from Metrohm Process Analytics is the most straightforward and easy-to-use tool to do so online.

About the Aluminum application

Al3+ is determined photometrical y with eriochrome cyanine R which forms a red-violet complex, measured at a wavelength of 572 nm. Al3+ reacts with the indicator in weak acid medium. The analyzer is able to handle a wide range of concentrations, from μg/L to mg/L.
