Investigations into Hair Analysis by ToF-SIMS

This research has applied Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) to a variety of investigations for studying hair. Hair grows in such a manner as to incorporate any xenobiotics existing in the blood stream into the actively growing segment. As the hair continues to grow (at a rate of approximately 1 cm per month) a histological profile is produced along the strand representing drug use, dietary habits, exposure to pollutants and toxins and also cosmetic treatments.
