Facile Lego-Spinner Pretreatment Device for Analysis of Arsenic Species in Dried Blood Spots by Ion Chromatography-Inductively Coupled Plasma-Mass Spectrometry

“…Most studies of TAs in the DBS not only require the extraction of arsenic using the expensive and bulky instruments such as centrifuges and microwave digesters but also require the pretreatment for 90 min or more, which may be detrimental to the study of the unstable arsenic species in air. − ,, Currently, a few small mixing and centrifugation units have been designed to simplify the analytical workflows, including egg beaters, paper gyroscopes, , fidget spinners, , centrifugal microfluidic devices, and ultrasonic devices, , opening up a new idea for the pretreatment of complex samples. The Lego-based devices have the advantages of small size, low cost, and flexible configuration and can be designed for different analysis tasks such as microscope and capillary electrophoresis. − Therefore, it is promising to develop a Lego-based pretreatment device for the extraction and separation of arsenic species in the DBS through the rational configuration of Lego components, so as to achieve the fast and efficient analysis of arsenic species in the DBS by IC-ICP-MS.…”
