Abstract | The paper describes an analytical method for on-site detection of MTBE (Methyl tert-Butyl Ether, CAS 1634-04-4) using ion mobility spectrometry (IMS). The ion mobility spectra of MTBE show a typical dimer ion with a reduced ion mobility constant k0 = 1,50 cm2/Vs. Using this signal, it is possible to measure the contamination of MTBE in water in the range > 30 μg/l. Interference of matrix compounds like alkane’s, alkene’s and cycloalkane’s can be neglected due to their low proton affinity. A simple and fast one-way sample preparation technique was developed for on-site analysis. For separation of MTBE from water and other volatile organic compounds (VOC’s), a water binding material (EXtrelut) in head space vials can be used. The gas phase above the EXtrelut is then injected in the hand-held IMS RAID-1 (Bruker Saxonia Analytik GmbH). The needed time for the determination of MTBE including sample preparation is about 5 minutes. Mobile GC/MS (EM 640 from Bruker Daltonik GmbH) was used for verification of the IMS results. Detection limits below 1 μg/l MTBE were obtained with the same sample preparation procedures. |
