New Series of Online Heavy Metal Analysers

DKK-TOA Corporation (Japan) has recently launched a new range of online heavy metal analysers, the HMA series.  This new range of instruments has been specially developed for difficult industrial and waste water applications.  There are five models in the series, providing measurements of Total Chrome, Hexavalent Chrome, Total Copper, Total Manganese and Total Nickel.  The measurement method is based on the colorimetric method.

The HMA series has been specially developed to provide extremely high levels of accuracy.  To achieve this, the measurement system features a specially designed high temperature digestion chamber. Conventional heavy metal analysers do not have this feature and typically use direct colorimetric methods. These conventional instruments are not capable of performing measurement of difficult heavy metal complexes in samples such as waste water. The high temperature digestion chamber of the HMA series with the addition of decomposing agents enables bonded metal components to be digested into the total metal content.

The HMA series also features low reagent consumption and reduced waste outflows.  This helps to reduce both reagent costs and costs associated with waste solution handling and disposal.

The development of the HMA series has been based on previous, field proven instruments with more than 1,500 existing installations worldwide. Excellent reliability and performance are therefore assured.
