S-Index Interpretation
The S-Index (Sharing Index) is a comprehensive metric that represents the cumulative impact of all your datasets. It is calculated as the sum of Dataset Index scores across all your claimed datasets.
What it means:
- A higher S-index indicates greater overall impact of your datasets relative to typical datasets in their fields of research
- The S-Index grows as you add more datasets or as existing datasets gain more citations and mentions
- It provides a single number to track your research data impact over time
Current S-Index: 1.5 (sum of 2 datasets Dataset Index scores)

Features of the dead (void) volume V0 determination of chromatographic columns with organic sorbents were considered. Two monolithic columns were studied: based on divinylbenzene – styrene (DVB-St), and based on 1-vinyl-1,2,4-triazole (VTr). Two methods were used for determination of columns’ void volume: (1) measuring the retention time of unretained components and (2) quantitative determination of the mobile phase (MP) components in the column (direct method). The first method depends on both the component nature and the MP composition, whereas the direct method makes it possible to obtain the void volume value that does not change in a wide range of the MP polarity. For the VTr column, the void volume does not change when the acetonitrile/water MP composition is varied from 100/0 to 20/80. For the DVB-St column, the void volume depends on the MP composition. This occurs due to swelling of the sorbent in a good solvent (high content of acetonitrile) and its shrinking in a poor solvent (high content of water). The absence of the void volume dependence on MP composition for the VTr column can be attributed to 1,2,4-triazole fragments hydrophility. As a result, the monolith is not shrunk at the water excess in the MP.
