Optimal ODS-L

Optimal ODS-L has a slightly lower carbon loading (15%) than the ODS-H and is useful for the analysis of a wide range of hydrophilic compounds which are normally not retained by other C18 based packing material.

One particular advantage is that even pure water can be used as the eluent without the need for any organic modifier. Highly polar samples only soluble in water may be separated by this packing material, e.g. sugars and other saccharides (see example below). Optimal ODS-L is also as useful for analyzing hydrophobic samples which are currently chromatographed on competitor C8 materials. Like ODS-H, this packing material is also fully end-capped.

Optimal ODS-L is also based on the same high purity silica as the Optimal ODS-H material which ensures the high degree of inertness and lack of peak tailing.
