A new rapid treatment of human hair for elemental determination by inductively coupled mass spectrometry
Advancements in sample preparation for performing elemental analysis are coming from the dissemination of microwave-assisted procedures, but there is still room for improvements by looking for fast and easily applicable procedures. In the present study, the open-vessel digestion sample treatment (19–21 °C or 95 °C) was compared with closed-vessel microwave-assisted digestion (180 °C). Detection and quantification limits, accuracy, precision, residual carbon content, and residual acidity were quantified with certified and in-field hair samples.
