The Acaros Gravimetric automatically prepares samples with high accuracy. It offers an integrated autosampler and autodiluter to efficiently process samples. Weighing tubes and their content, diluting, mixing, sampling, steering and transporting them to the ICP analyzer are just a few examples of preparation steps that are performed automatically by this solution. It enables processing and analyzing of samples in a controlled, highly accurate, reproducible and time-saving way. The process can be performed according international standards (e.g. ASTM or DIN). In addition, the Acaros is able to calibrate the ICP analyzer and to handle, check and interpret the gathered data.
