Multi-analyte methods and high-resolution mass spectrometry for hair analysis

This chapter focuses on discussing the mass-spectrometric instrumentation most commonly used in hair analysis, together with its evolution following both technological advancements and new analytical challenges that involve hair testing. As a matter of fact, parallel progress of hair testing queries’ complexity and the performance of mass-spectrometric instrumentation is observed. In turn, these analytical performances are strictly connected with technological innovations and original devices concerning mass spectrometers. For this reason, only the most recent studies (i.e., from around 2016) have been considered, the former being covered in a preceding book.
