Maclachlan 1 , John N. Driscoll 2 INSTITUTIONS (ALL): 1. PID Analyzers, LLC, Centerville, MA, United States. 2. PID Analyzers, LLC, Sandwich, MA, United States. ABSTRACT BODY: Abstract: The photoionization detector (PID) consists of a short wavelength lamp adjacent to an ionization chamber. The UV lamp will ionize hydrocarbons that could be encountered at an arson site and have ionization potentials (IP) greater than 10.6 eV. The major components in air have high IPs and are not ioni
