Abstract

|
|
| High spatial resolution and sensitivity make electron energy loss spectroscopy (EELS) and electron spectroscopic imaging (ESI) excellent techniques for localizing low levels of titanium (approximately 2 wt.%) in ultrastructural features as small as cross-sections of chemically modified chrysotile asbestos fibres (i.e. 20 nm diameter). Visible beam damage, ie. mass loss and morphological changes, was drastically reduced when a Zeiss EM 902 fitted with a cryoholder was used to perform ESI using the three-window background extrapolation method. The electron micrographs revealed that the titanium distribution is located not only at the external surface of the fibre but also inside the fibril tube. |
