  • Breath ethanol concentration was monitored in five participants post-alcohol intake.
  • Gas chromatography was used as a parallel reference method.
  • Data analysis involved projection to latent structure (PLS) and artificial neural networks (ANN).

    • Main Results:

    • The electronic nose system successfully quantified breath alcohol concentration.
    • A best-case root mean square error of 16.8 mol ppm ethanol (0.037 mg/l) was achieved.
    • Significant development is needed, particularly for the sensor devices.

    Conclusions:

    • The multisensor array shows potential for breath alcohol analysis.
    • Further technological advancements are necessary for optimal performance in forensic settings.
    • The study highlights the need for improved sensor devices for accurate alcohol quantification.
