252‐Cf particle‐induced desorption mass spectrometry (PDMS) has been used to follow the modification of chrysotile asbestos fiber with organosilane compounds. Monitoring changes in the peak area ratios of Si + , Mg + and SiOH + ions in PDMS and atomic ratios from XPS, the formation of organosiloxane polymers vertical to the surface is suggested. Changes in the ratios also indicate differing coverages of the modifiers, owing in part to steric effects associated with the different organic substituents. The fibrous, non‐conductive nature of the sample did not impair the analysis with 252‐Cf PDMS. This application lends further support to the belief that PDMS is a surface‐sensitive technique.
