A few clusters surface-enhanced Raman scattering (SERS) measurements on a substrate covered with a layer of practically SERS non-active metal were realized. We measured SERS spectra dominated by the contribution from only a few carbon clusters for hydrogenated carbon deposited on the nickel-modified silver substrate. It means that a few molecules SERS measurements on many catalytically important metals can be realised. In recorded spectra the contributions characteristic for various clusters could be identified (and hence presence of these clusters in the analysed mixture could be proved), even when contribution of many types of carbon clusters to the standard (averaged) SERS spectrum cannot be reliably identified.
