- •
Lab-On-Valve employing bead injection is used for iron preconcentration in seawater.
- •
Handling of cellulose beads is firstly studied on Lab-on-Valve platform.
- •
A novel configuration allowing easy elute recover for later reaction is proposed.
- •
Universal approaches for bead handling and bubble removal from carrier are proposed.
- •
4.1% RSD of peak height, 2.3% of column formation & LOD of 5 nmol L−1 were found.
