Abstract

BACKGROUND: At present, 3D printing technology is becoming increasingly popular in analytical chemistry because it enables the rapid and cost-effective manufacture of sample preparation devices, particularly in flow-based operation, opening up new opportunities for the development of automated analytical methods. In parallel, the use of miniaturized methods and sustainable solvents in sample preparation is highly recommended. Accordingly, in this work, a 3D-printed millifluidic device was designed and used for the on-line natural deep eutectic solvent (NADES)-based liquid phase microextraction (LPME) coupled to a spectrofluorometer for, as a proof of concept, the determination of thiabendazole (TBZ) in fruit juice samples. RESULTS: , respectively, which are well below the maximum residue levels (MRLs) set by the European Union. The greenness and applicability of the proposed analytical method were evaluated using the AGREEPrep, SPMS and BAGI tools and compared with other published methods. In general, the proposed method was superior to others, mainly due to its high sensitivity and high sample throughput. SIGNIFICANCE: Several cells were easily designed with different channel geometries (length and depth) to find the optimal dimensions, and then 3D printed and tested in a relatively fast, cheap and simple way, demonstrating the suitability of 3D printing in the fabrication of millifluidic devices as an alternative to traditional fabrication techniques. In addition, the proposed approach is fully compatible with new sustainable solvents, facilitating the development of green sample preparation methods.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
