    I am searching external reliable lab to test PAHs in Georgia or neighboring states. Do you have any advices?  The testing method is shown below.

    Sample preparation is to  chop up the samples to be analysed (using scissors, wire cutters, pliers, etc.) should have a maximum size of 2 – 3 mm. Then  500 mg of the sample is placed in a glass "Bördelglas" ("vial"). To this 20 ml of toluene. The sample is then extracted for 1 h in the ultrasonic bath at a temperature of 60 °C throughout. The gas chromatography is run to analyze. The equipment parameters (temperatures, columns, mass traces) may be chosen by the individual laboratory or are determined by the analytes.

    The method of determination to be applied is gas chromatography with a mass-selective
    detector in the SIM mode.
    The following 18 PAHs are to be determined:
    • Naphthalene
    • Acenaphthylene
    • Acenaphthene
    • Fluorene
    • Phenanthrene
    • Anthracene
    • Fluoranthene
    • Pyrene
    • Chrysene
    • Benzo[a]anthracene
    • Benzo[b]fluoranthene
    • Benzo[k]fluoranthene
    • Benzo[j]fluoranthene
    • Benzo[a]pyrene
    • Benzo[e]pyrene
    • Indeno[1,2,3-cd]pyrene
    • Dibenzo[a,h]anthracene
    • Benzo[g,h,i]perylene
