Categorisation of biological deposits using matrix assisted laser desorption ionisation mass spectrometry

摘要

A method of categorising a human according to pre-determined categories using Matrix Assisted Laser Desorption Ionisation Mass Spectrometry (MALDI-MS) is disclosed. A method is provided to discriminate humans based on gender, for example, by comparing MALDI-MS sample spectral data in the m/z range 2,000 to 30,000 and comparing these sample spectral data with reference spectral data obtained from pre-categorised humans.
