Analysis Examples

Multiple Pesticides with a Wide Polarity Range
Simultaneous analysis of multiple pesticides with a wide polarity range from hydrophobic to hydrophilic has been achieved using the
Nexera UC and 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.
