JA date took air samples was 7/21/08 - needle syringe - inside trunk - 8" needle - didn't open and inspect the trunk no - didn't know the trunk liner was removed and spare tire cover removed 4 days before -no didn't know that....4 days after was the air sample....how much is 250 microliters...a micro liter is one millionth of a liter - about the size of width of pencil lead and length of draw on syringe maybe 1/4"....not very much air.....inject into tevlar bag....taken to lab
on 21st pulled 2 samples first one was 1 liter and second was
triple sorbent trap -
held by OCSO a deputy brought a 300 ml tevlar bag to ...on morning of 22nd...Dr. Vass uses triple sorbent trap by Dr. Vass
pull air thru 3 traps - each of them pull out different components - if you pull out 10 liters of air you get what was in 10 liters of air.
in air samples itself - some weak organic compounds then went to next level - ambiant air and allow chemicals to attach itself to ...but that sample method isn't as good as triple sorbent trap- the triple sorbent trap a better methodology for sampling @ low concentrations of air sample....a better method than casrbon strips...used best method to try to determine what was in air in trunk....doesn't tell you where it came from....if a particular object in trunk - if those items were isolated and test the air to collobrate to equalize the amount of the compound in the air....one methods to place item in tevlar bag to offgas - acceptable approach....
even with methods able to use...with trunk liner gone - still able to detect chloroform and TCE and dimethaldisulfide.....on that limited sampling those chemical are consistent with research out there about human decomp - those components are in peer reviewed lit....can come from other sources as well..
chloroform can come from bleach and reaction with other components....in literature in finding it in swim pool water - one article where chloroform was in swim pool - minor amounts and there should be other components when chlorine and chemical components....if bromine is present and chlorine together hypobromois acid ...methane and hydrochloro acid....as long as bromide there to form hypobromis acid...
any case in literature about chorine caused by bathing suit in trunk or accidental create chloroform with chlorine (cl2) natural form of chlorine...suspect that material hydrolize with water or dissapate....anything in your eval of air sample that chlorine came from some inadvertant reaction between pool chlorine and ......nothing in our results to indicate source of tetrochloroetheline and the other there.
ed is not in human decomp - odor from trunk when you inspected it...but no back g round in identify odor...

found these slight traces of chloroform in only 2 samples tested in 5A and 5B? no sir I believe it was the #3 40 min micro-extract and the 2 solid phase from 7 1/2 hrs also contained those compounds....don't know the source of any those 3.....main thing there was gasoline? the predominat chromatograph profile was gas....created report on 7/30 3 years ago....based on circumstances car in garage - trunk liner removed - surprised to find elements of gas.....No not surprised to find that
witness excused
