A portable electroanalytical system applied for rapid and simultaneous determination of uric acid (UA) and nitrite (NIT) in human biological fluids (urine, saliva and blood) is reported. The system is based on batch‐injection analysis with multiple‐pulse amperometric (BIA‐MPA) detection using screen‐printed electrodes (SPEs) modified with multi‐walled carbon nanotubes. Sample dilution in optimized...
Herein, a compact batch injection analysis cell for screen printed electrodes (BIASPE cell) is reported. The proposed system shows several requirements of a portable system that include easy‐to‐operate (“user‐friendly”), high‐speed quantitative and qualitative analysis, excellent cost effectiveness, and low‐power requirements (all auxiliary components are battery‐powered). Similar to analytical microsystems,...
