In this study, Dr. Grand presents a compact, low-maintenance programmable flow injection (pFI) approach for the direct analysis of dissolved aluminium in seawater. The method achieves sub-nanomolar sensitivity, with a detection limit of 0.5 nM, precision better than 3%, and negligible matrix effects. Notably, the technique allows for calibration using ultrapure water, eliminating the need for complex matrix matching and making the method particularly well suited for routine laboratory and field-based applications in chemical oceanography.

To support reproducibility and broader adoption of the technique, an accompanying GitHub repository has been released. The repository includes all pFI sequences and FloZF configuration files used in the study, enabling other researchers to readily replicate, adapt, and extend the method for their own analytical needs.
