Studies concerning the distribution of inorganic wood preservatives in cell wall layers based on LAMMA

Summary The Laser Microprobe Mass Analyzer (LAMMA) proved to be a useful instrument for element localization in single wood cells treated with preservatives. The relative concentration of elements occurring within the cell wall can also be determined. Even those with low mass numbers, namely boron and fluorine, are identifiable. In this respect, LAMMA-analysis is preferable to electron probe X-ray microanalysis.Poles treated with CCF- or CCB-preservatives exhibit an overall gradient of ion concentration across the sapwood. Chromium becomes more strongly fixed in the wall than copper. Relative to these elements boron becomes rather irregulary distributed. Moreover, the adsorption of fluorine is considerably low.
