The results from Raman spectroscopy analysis of salt aqueous solutions at ?170℃ demonstrate that for those clearly sharp iron peaks whose Raman wavenumber is close to each other such as NO 3? and CO 32?, their original shape could be restorable by the stripping technique, and that ice’s sharp characteristic peak (3090―3109 cm?1) is steady, while the spectrum band of the complex compound (nCl?―[H+―OH?]n) chlorine ion combined chemically with water molecule is 3401―3413 cm?1. On the other hand, the research shows that the higher the negative iron concen-tration, the stronger its Raman characteristic peak intensity and the smaller the ice’s. Based on the number of data and theoretical work, the strong correlation of the molar concentration of negative ion with the Si /SH 2 O band area ratio is built up. Moreover, the developed Raman method is successfully used in the component analysis of the field fluid inclusions from Silurian sandstone in Tarim basin.
