“…Electrical contact with the instrument is realized by means of a conductive wire which was soldered or wrapped to the metallic part of the mechanical pencil holder [9,19,21,22,[24][25][26][27][28][29][30][31][32][33][34][35][36][37] (Figure 1a). A micropipette tip [38], an insuline syringe [39], a glass cappilary [40,41], or a plastic [16,[42][43][44][45][46] (Figure 1b) or Teflon tube [47][48][49][50][51][52] (Figure 1c,d) can also act as holder. An araldite mixture (epoxy resin, 1:1) [16,41,[43][44][45], bentonite [38,39], or cyanoacrylate glue [40] was used to fix the graphite lead into the support.…”

“…Sometimes, the graphite lead electrode is polished with an alumina slurry [25,41,47,59,67], on sandpaper with different granulometrics [40,42,68], on emery paper [41,[49][50][51][52]69] followed by a butter sheet [16,45], on butter paper [39], or on weighing paper [20,57,58,62,70]. Yen et al [71] reported that amoxicicllin presented a better electrochemical response at the PGE mechanically treated with polishing paper in comparison with the original electrode.…”

“…Other modified PGEs were manufactured by dip [17,61,69,87,88,90,92,127,132,133] or spin coating [48,[50][51][52]125,126,134]. Drop coating was applied to produce Mo 5 O 8 /PGE [34], Trypan blue-modified PGEs [44], different CNT-modified PGEs [47,57,58,68], or PGEs covered with various modifiers [41,49,62,65,135]. After that, the modified PGE was dried either in air [35,48,52,66,68,69,90,136] or in other well-established conditions (e.g., in a desiccator [50] or at a certain temperature [125,137]).…”

The even growing production of both well-known and new derivatives with pharmaceutical action involves the need for developing facile and reliable methods for the analysis of these compounds. Among the widely used instrumental techniques, the electrochemical ones are probably the simplest and the most rapid, also having good performance characteristics. However, the key tool in electroanalysis is the working electrode. Due to the inherent electrochemical and economic advantages of the pencil graphite electrode (PGE), the interest in its applicability in the analysis of different analytes has continuously increased in recent years. Thus, this paper aims to review the scientific reports published in the last 10 years on the use of the disposable eco- and user-friendly PGEs in the electroanalysis of compounds of pharmaceutical importance in different matrices. The PGE characteristics and designs (bare or modified with various types of materials), along with their applications and performance parameters (e.g., linear range, limit of detection, and reproducibility), will be discussed, and their advantages and limitations will be critically emphasized.

“…PGEs present good electrochemical characteristics and are cheap, easily commercially available, and simple to use. Thus, in recent years this type of electrode has gained even more applicability in voltammetric analysis of pharmaceutically [33][34][35][36][37][38][39] and biologically [40][41][42][43] important compounds.…”

The present paper describes the voltammetric analysis of dipyridamole (DIP) at a cheap, disposable pencil graphite electrode (PGE). The working conditions were optimized with regard to the electrode material and the supporting electrolyte. Cyclic voltammetric investigations emphasized that DIP is irreversibly oxidized at the PGE. The electrode process is pH-dependent and controlled by both diffusion and adsorption. For DIP quantitative determination a differential pulse voltammetric (DPV) method in phosphate buffer solution pH 7.00 was developed. DIP's oxidation peak current varied linearly with the analyte concentration, presenting two linear ranges, namely 5.00 × 10 −7-2.50 × 10 −5 M and 2.50 × 10 −5-2.50 × 10 −4 M, with detection and quantification limits of 1.21 × 10 −7 M and 4.03 × 10 −7 M DIP, respectively. The newly developed DPV method using the inexpensive, disposable PGE was successfully applied for the simple and rapid determination of DIP from pharmaceutical formulations.
