| Abstract: | The durability of wood is improved by wood preservatives. Due to new environmental legislation, commonly used active ingredients
such as chromium and arsenate are being replaced by alternative and more environmentally friendly preservatives. However,
the alternative wood preservatives are more difficult to detect in the wood. Detection of the preservatives is necessary in
order to monitor millwork production for qualitative assessment of the wood preservative uptake. The aim of this study is
to examine the use of solid phase desorption-ion mobility spectrometry (SPD-IMS) can be used for rapid detection of the wood
preservatives propiconazole and tebuconazole in Scots pine (Pinus sylvestris). The findings proved that SPD-IMS is capable of detecting and distinguishing wood preservatives directly from treated wood
shavings. SPD-IMS requires no additional sample preparation or extraction of the wood sample. The findings show that SPD-IMS
is a fast and easily applied method for direct detection of propiconazole and tebuconazole in small wood samples. |
