Abstract
An analytical method for quantifying the volatile anticancer drugs ifosfamide (IF) and cyclophosphamide (CP) in air was developed on the basis of thermal desorption (TD)-gas chromatography-mass spectrometry. Polydimethylsiloxane-coated macroporous silica was used as the adsorbent. The extraction tube was prepared by packing 0.2g of adsorbent particles into a glass tube. The extraction and desorption efficiencies of the proposed method were quantitatively investigated in this study. The limits of detection of the proposed method for IF and CP were 3.3ngL-1 at an air sampling volume of 3.0 L (30min). The sensitivity of the proposed method was compared with using a Tenax TA packed tube that is widely used as the extraction medium in TD analysis. Finally, detection of IF and CP that evaporated from aqueous standard solution was investigated.
