Fast Detection of Wood Preservatives on Waste Wood with GC/MS, GC/ECD and Ion Mobility Spectrometry

摘要

New methods for the detection of wood preservatives are presented. A portable battery powered ion mobility spectrometer (IMS) has been provided with an injector for direct insertion of small wood shapes cut from the sample. Compared to GC/MS and GC/ECD, operated with fast methods on mobile equipment, IMS seems to be favorable. Compound identification by spectra, extremly low analysis time of less than 1 minute without sample treatment, low cost per analysis and good portability of the equippment are the advantages of IMS.
