Moderator introduced the final morning presentation and named Kyle Burks of the Harris County Institute of Forensic Sciences as the presenter on rapid peptide analysis using matrix‑assisted inlet ionization and paper‑spray ionization mass spectrometry.

Keywords:

Speakers:

A Harris County Institute of Forensic Sciences researcher described rapid peptide analysis methods — inlet ionization and paper-spray ionization on an AccuTOF-type mass spectrometer — showing how labs can presumptively identify high‑mass peptides (including human growth hormone and other peptides) for investigative use and to give prosecutors more information. The presentation noted National Institute of Justice funding and practical hurdles in acquiring peptide standards.
