Analysis Examples Tocopherol isomers

Comparison of retention and resolution of tocopherol isomers between LC condition and SFC ones

Comparison of retention and resolution of tocopherol isomers between LC condition and SFC ones


Isomers and structurally similar compounds that are difficult to separate can be analyzed by Nexera UC and Shim-pack UC series at high speed.
In this example, four kinds of tocopherol isomers were analyzed by Nexera UC and Shim-pack UC-Sil.
As indicated on the right, analysis time was reduced to one-third the time achieved with conventional HPLC method while resolution was improved.

Analysis of phospholipid classes


The example on the left shows the result of the analysis of phospholipid classes using Shim-pack UC-Diol with Nexera UC.
The ODS-based Shim-pack UC-GIS II can also be used to analyze molecular species of phospholipids with the same modifiers.
Nexera UC and Shim-pack UC series are ideal for analyzing complex samples.

 

 

Analysis Examples Multiple pesticides with wide polarity range

Simultaneous analysis of multiple pesticides with a wide polarity range from hydrophobic to hydrophilic ones has been achieved using the Nexera UC using Shim-pack UC-RP.
Shim-pack UC-RP contains a polar functional group embedded between the silica surface and the C18 group. This allows the column to analyze a wide range of components from hydrophobic to hydrophilic ones.
Simultaneous analysis of multiple components can now be performed more efficiently using the Nexera UC and Shim-pack UC series.
