- Abstract
- The features of gas chromatographic identification of 80 common low-boiling organic solvents based on retention indices on standard non-polar polydimethylsiloxane stationary phases were examined. It was shown that one-dimensional analytical parameters, such as retention indices, cannot provide unambiguous identification of all compounds in this group, as the informativeness criterion R(RI) for this group is only about 29, which is less than the number of compounds. To address this issue, supplementing chromatographic data with independent characteristics, such as refractive indices (n ), is recommended, as their determination requires minimal time and sample amounts. However, about 10% of the solvents cannot be distinguished even by combining RI and n . For comparison, the potential use of dynamic viscosity values as an additional analytical parameter was considered. The provided table of retention indices for the most common organic solvents is of independent value for analytical practice.
