Abstract

This paper presents the results of investigations of chemically modified fibers comprising an immobilized compound that yields ethene as the analyte in generated standard gaseous mixtures. Prior to chemical modification, the fibers were coated with a thin aluminum layer to improve their mechanical strength. Commercially available Al-coated fibers were used in this work. During thermal decomposition of the immobilized compound, reproducible quantities of the analyte per unit fiber length were obtained for all the investigated fibers (fiber diameter (microm)/outside diameter (microm) of the Al-coated fiber=110/146, 220/300, and 660/830), amounting to 0.685+/-0.032, 0.8300+/-0.0081, and 1.092+/-0.010 ng cm(-1), respectively. The proposed procedure can be used successfully for the generation of measured component of matrix-free reference materials.
