Results


The result of the SIM mode should be something like this.

Discussion


Detection limit


The World Health Organization Air Quality Guidelines for Europe, the unit risk is 9 X 10(-5) per ng/m(3) of B[a]P as indicator of the total PAH content, namely, lifetime exposure to 0.1 ng/m(3) would theoretically lead to one extra cancer case in 100,000 exposed individuals. This concentration of 0.1 ng/m(3) of B[a]P is suggested as a health-based guideline.



This method is actually sensitive enough to be able to detect concentration of PAHs at such a low limit.

A plot to show the change in sensitivity with the change in initial PTV inlet temperature.


A plot to show the linearity with a given change in volume injected.
