| Popis: | Changes in the concentration of solute molecules in a glycerol matrix were studied using mass spectrometry of secondary ions that appeared under the bombardment of a sample-solution by primary ions. The objects of study were several organic dyes and glucose oxidase. The concentration of solute molecules in the surface layer of the matrix was determined by the competition between the destruction of analyte molecules by primary ions and the replenishment of the number of undamaged molecules as a result of diffusion from the bulk. |
