Tlc Plates

The influence of a supporting matrix in surface-enhanced Raman spectroscopy (SERS) has been investigated. The support matrices were conventional TLC plates onto which Ag colloidal hydrosols mixed with the dye pararosaniline had been deposited. The protocol of preparation of the Ag sol as well as the type of TLC plate had a profound effect upon the intensity of the SERS signals of pararosaniline. The Ag sol and the TLC plate that resulted in the maximum SERS intensities yielded a detection limit of ∼ 108 femtomols (33 pg) of dye deposited onto the TLC plate. Deposition of the dye/sol mixture onto the supporting matrix also resulted in stable SERS signals for extended periods of time, in contrast to the solution-phase case, where the signal is only transient in nature. In order to obtain the SERS spectra, a remote sensing Raman spectrometer was constructed and is described.

Raman Spectral Analysis

Here we explore and review some of the latest ideas and applications of Raman spectroscopy to the volcanological sciences. Firstly, we provide a brief overview of how Raman spectral analysis works and how spectra from silicate glasses are interpreted. We then look at specific applications of Raman spectral analysis to the volcanological sciences based on measurements on and studies of natural materials in the laboratory. We conclude by examining the potential for Raman spectral analysis to be used as a field based aid to volcano monitoring via in situ studies of proximal deposits and; perhaps; in remote sensing campaigns
