“…It is well established that fabricating products with a distributed desktop 3-D printer result in lower costs for scientific equipment [1] , [2] , [4] , [29] , [31] , [32] , [33] , [34] , [35] , [36] , [37] . Similarly, automation with an Arduino is also known to reduce costs for a wide variety of experimental disciplines [1] , [2] , [4] , [38] , [39] , [40] , [41] , [42] , [43] . It should be noted that the use of the Arduino is not the lowest possible cost, as the microcontroller chips can be built into a custom PCB for less money than buying even the lower costs Arduinos (e.g.…”

“…Conventionally, in many cases the CPT is preceded by an APT to clean the BDDE surface, oxidizing any strongly adsorbed organic contaminant . For example, the electroanalytical determination of the herbicide picloram was carried out using a CPT‐BDDE, whose pretreatment was always preceded by an APT; the CPT or APT involved polarizations at −2.0 V or +2.0 vs .…”

The several outstanding properties of boron‐doped diamond electrodes (BDDEs) have allowed their application for various purposes, among them electrochemical sensing. However, the electrochemical response of many redox species on BDDEs can be strongly dependent on whether their surfaces are predominantly hydrogen‐ (HT) or oxygen‐terminated (OT). Fortuitously, electrochemical pretreatments themselves can be used to enrich in situ the BDEE surface in one or the other type of termination. The surface of a cathodically pretreated BBDE (CPT‐BDDE) becomes enriched in HTs, whereas that of an anodically pretreated BDDE (APT‐BDEE) becomes enriched in OTs. Thus, when suitable, the electrochemical activity of a BDDE for a given analyte may be tuned by electrochemical pretreatments, yielding enhanced sensing properties. The main purpose of this review is the compilation and discussion of papers published after 2009 reporting on electroanalytical applications based on a CPT‐BDDE or an APT‐BDDE. Procedures to perform proper electrochemical pretreatments are also discussed.

“…A typical Arduino board is usually composed of a controller, some digital and analog E/S lines, complementary components (that facilitate the programming and interconnection with other circuits), besides a serial or USB interface to connect to the microcomputer, which is proactively used and interact with board in real time. [33][34][35] The choice of the Arduino microprocessor was a design option and an optimization of the cost-benefit ratio. However, the circuit presented in the present article can also be developed with a PIC ® microcontroller, such as those developed by ChipKIT™ or Microchip ® , they are great options for FIA projects such as this presented in this study, or even more sophisticated projects.…”

“…It was obtained enrichment factors of 20 and 16 and LOD values of 1.4 and 4.8 μg L -1 , respectively. 40 Given the great importance of developing automated analytical methods that meet society's current demands for rapid and reliable analysis of several matrices, the present work aims to use Arduino [41][42][43][44][45][46] in the development of an analytical approach using multivariate designs. A two-level fractionated factorial and Doehlert matrix were applied for the extraction optimization, allowing a new and rapid automated preconcentration system, using a couple of knotted reactors for the Mn determination in tea samples by F AAS.…”

In the present paper, an automated online preconcentration system based on the use of two knotted reactors (KR) was developed for Mn determination in tea samples by flame atomic absorption spectrometry (F AAS). The system automation was performed by using four solenoid valves to switch sample streams and reagents. Valves were driven electronically by an integrated Darlington transistor circuit and controlled by an open-source Arduino hardware platform written in C language. The preconcentration was based on the precipitation process of metal ions complexed with 2-(5-bromo-2-pyridylazo)-5-(diethylamino)phenol (5-Br-PADAP) on the inner walls of the reactor, followed by elution with a solution of hydrochloric acid. The optimized system allowed the Mn determination with limit of detection (LOD) of 2.1 mg L-1 , precision (relative standard deviation (RSD), 50.0 mg L-1) of 2.6% and enrichment factors of 8. The system presented a sampling frequency of 60 h-1. The method accuracy was evaluated by analysis of the certified reference material (CRM) apple leaves (NIST 1515) and by addition/ recovery tests obtaining recoveries between 95.2 to 119%. This method was applied in the Mn determination in commercial tea samples purchased from local trade. Manganese levels were found in a concentration range of 2.95 to 123 μg g-1 .
