Automation in arthrosis research

Widespread medical studies require the analysis of suitable sample numbers to discover certain effects. Arthrosis treatment with hip and knee joint endoprostheses introduces multiple materials into the human body. Metal-containing implants may release several degradation products. Certain concentrations of chromium, cobalt, nickel, titanium and aluminum may affect multiple organs. The determination of metal concentrations in body fluids is one way to prevent severe intoxication from implants. In addition, the study of metal distribution and accumulation in individual organs will deliver extended information. In contrast to well automated high-throughput screenings, analytical measurements are mostly performed manually due to their complex process structure. A new study published in the journal Molecules presents a semi-automated sample preparation and measurement system for the determination of metals in autopsy tissue using inductively coupled plasma mass spectrometry (ICP-MS). In this auto-commentary, the main findings are highlighted and discussed.
