Ok man, you can't determine the three things at the same time, not for now that I know. First you have to divide your air samples, one part for PAH's extraction, one part for carbon and one part for ions. PAH's part must be the biggest since some PAH's are in low concentrations compared to the other chemicals. Then you have to perform three methods:

-PAH´s extraction using an organic solvent. There are severa articles in reference to this. I have an article you can use, is applied to other pollutants but can be useful to apply for PAH´s. After extraction you need to perform GC-MS analysis.

-Ions extraction need to be performed using water based extraction and then Ion chromatography.

-For carbon you can do a thermal or combustion gravimetric method.

Sound like you have a lot of work to do, but first you have to read a lot.

Thanks for the assistance. I appreciate you

Hi Francis Olawale Abulude,

You can find several methods on the USEPA website. Follow the link: https://www.epa.gov/amtic

Also you can find a good review of methods and techniques on this work: Article Trends in analytical techniques applied to particulate matte...

Dear Elson,

I appreciate your contribution. I will try it
