JA w/ Dr. Vass
research continued after 2004 pubish.....also look @ decompose on the surface....skelneton bones..... different type of tech used finally....instead of carbon traps.....speamy fibers (solid phase macro-extraction)
work w/above ground bodies .....antrhopology research facility .....body farm.....10 surface decomp.....some lying on surface....some loosely covered.....buried ......piping systems little ports on end of each pipe......collected air into TST triple sorbent trap.....3 types of activated carbon....little piece of metal activated......air passes thru TST remove odor components capture on activated carbon.....same procedure used on surface individiuals.....placed ..trap on surface, dangled close to body .... use an air pump draws air from enviroment to lab......tube removed ends sealed with nuts....brin back to lab....thermal absorbtion......heat up metal tube - gas goes thru.....as tube heats activated carbon releases into gas chromatogram......cryoloop........tiny little metal loop @ -321F......condenses and freezes odor molecule....concentration techniquie....as heat up....compounds become volital again........cryofocus is to concentrate sample.....triple traps used in buried remains and above ground remains......studied above ground remains 2004-06, inital stages of decomp frequency of samples weekly, then bi-weekly, skeletonized went to monthly.....surface individuals more frequently.......
update 2004 info with new info in 2008.....Expert in Forensic Anthropoligy...(object-
materials in criminal case YM from OCSO.....discussion with him.......sent items of evidence to examine.....metal evidence can.....States exhibit IO - don't recognize outside box.....(giggles no looks like a box)......open box and loook @ contents
