Multiple Headspace Extraction (MHE) method used for extraction quantitative analysis followed by gas chromatography (GC) analysis. A GC with flame ionization detector (FID) instrument BT. This offers advantages pollutants because it eliminates use solvents various purification steps often lead erroneous results. MHE independent standard could be wide range Hot Oil without calibration different ranges. Also, linearity, detection limits, accuracy looked into as part validation process. limit (LOD) quantification (LOQ), respectively, between 0.05 - 0.56, 0.17 1.9 mg/kg.
