Hazardous air pollutants (HAPs) have high toxicity and bioaccumulation potentials into human body even insmall amount (levels of ng/m3establish the analysis method for correct results. In this study, various analysis methods of VOCs and Aldehydeswere compared in order to select the proper methods in our condition. Sampling and analysis method of VOCswere followed to EPA TO-14a and TO-17. VOCs were collected in absorption tube and separated by thermal-cartridge and extracted intosolution then analyzed by HPLC as the same condition of EPA TO-13a.This study also shows the results of QA/QC system of selected methods. Some experiments could be improvingthe data assurance blank test, calibration check, repetition precision check, the determination of detection limit and~ 9% and 1 ~ 4% RSD,respectively. Recovery rate of VOCs showed variable ranges from 60 to 133.5%. MDL of VOCs and aldehydeswere 0.044~ 0.284ppb and 0.14~ 1.02ng, respectively.
