Re: !*URGENT*! dioxin chemical test

This is what i have written so far...however i need a detailed method... the only problem is everything i have been reading re: HRGC/HRMS is so jolly confusing. I seriously do not get the method... but anyway this it what i've got...

The presence of dioxins require a highly sophisticated method to present results as the readings may be extremely minute, but nevertheless they are significant. Dilution High Resolution Gas Chromatography/High Resolution Mass Spectrometry (HRGC/HRMS) is used in dioxin detection.
Results are measured in parts per trillion (ppt)...



the method can be found here...
http://www.arb.ca.gov/aaqm/qmosopas/dioxins/methods/1613.pdf
it starts at the bottom of page 4... for anybody who happens to read this post between now and 8am
if you understand it could you please post- really appreciate it

thankx again x
