A flow-batch analyzer using a low cost aquarium pump for classification of citrus juice with respect to brand

► Novel flow-batch analyzer using a compact, low-cost aquarium pump instead of a peristaltic pump. ► Classification of citrus juice samples with respect to brand on the basis of UV-vis spectra. ► Multivariate classification employing SIMCA, PLS-DA and SPA-LDA. ► Correct classification of all samples by using the proposed flow-batch analyzer.
