In this work, we present a simple homemade batch‐injection analysis cell for screen‐printed electrodes (BIA‐SPE). The potential of the proposed system for on‐site analysis was demonstrated by the determination of carbendazim, catechol, and hydroquinone in tap water. The system provided reduced injection volume (30 µL), high analytical frequency (≈200 h −1 ) and low detection limits (nanomolar level). Moreover, the BIA‐SPE cell presented better stability ( RSD ≈0.4 %) than a conventional flow injection cell for SPE ( RSD ≈5.0 %) in organic media. The proposed homemade BIA‐SPE cell is very simple, inexpensive and can be easily constructed in any laboratory.
