JB moves to strike previous testimony. HHBP - NO
Initial exam - large peak (chloroform). Chloroform is a compound he has dealt with in his research. It is an identified decompositional event product. The level of chloroform was shockingly and unusual. There were also a variety of very small peaks. They then tried to concentrate the air sample.
He was with Dr Wise in the room as the next round of analysis was done.
They removed the piece of carpet from the can.
JB objected - overruled.
They removed the carpet from the can and placed it in a plastic bag (Tevlar plastic bag designed as a product to contain air samples for testing). They put the sample in the bag and incubated it for two days at body temperature. The carpet came from the trunk of a car in Florida. They estimated temp in trunk was high nineties. They were trying to get the substance in the carpet to be released into the air specifically.
They extracted 10 ml through the chryo trap concentration procedure and then examined it in the GCMS.
JB objection - overruled.
Results of concentrated analysis - 55 individual chemical components - one was chloroform. Chromatogram showed large, tall peaks indicating a greater concentration. The largest or base peak was chloroform. The amount surprised him - they were SHOCKED. They had never seen chloroform of that level in environmental samples in 20 years.
Chloroform is a by-product of decomp - but in very small amounts - parts per trillion. They tried to quantify it in the sample. They injected a standard of chloroform in a known standard to verify their findings. They were then able to make a rough approximation of amount of chloroform - rough approximation - parts per million vs. parts per trillion that he had seen before.
They could not further quantify it because they needed a more concentrated standard. Further quantification really wouldn't have been helpful to them.
Chloroform has a high rate of evaporation - similar to gas.
Objection by JB - overruled.
Chloroform appeared in the trunk, over time it has evaporated - car was in tow yard, anthony garage, forensics lab. Then sample was taken. They could not approximate the quantity at an earlier time.
Also tested a piece of carpet from another vehicle to determine if chloroform was naturally present. He was shown chromatograms from the control carpet and ICA's car.
JB objection - document admitted into evidence at #123 - then published to jury over defense objection.
