[en] Fibers of different textile materials, such as polyesters, viscose, and wool, were analyzed using TXRF, yielding a 'fingerprint-type' trace element pattern. This pattern can be compared with quantitative results obtained from weighable amounts, e.g. 50 μg of the material. It can be shown that, besides the omnipresent elements Ca, Fe and Zn, some of these materials contain specific elements, such as P, Mn or Sb, and that an identification is possible using these elements even when very small amounts of sample are involved (i.e. sub-microgram). Since many synthetics contain Ti as a matting additive, the Ti concentration can be used to further differentiate the sample material. (author)
