“…Regarding methods reported in the literature, chromatographic [8][9][10][11] and microbiological [12][13][14][15] are the most widespread. Nevertheless, several spectrophotometric [16][17][18][19][20], spectrofluorimetric [21,22], and electrochemical [23] methods can also be identified. The separation methods usually provide good analytical performance although they require specialized apparatus and often expensive and hazardous reagents employed in significant amounts.…”

A simple smartphone-based digital image colorimetry is proposed for the determination of vancomycin in drugs. The analytical method relied on the reaction of vancomycin with copper(II) in ethanol–water medium with pH 4.3. The reaction resulted in the formation of a blue–grey complex, presenting an absorption maximum at 555 nm. A mobile application was used for smartphone-based analysis to decompose the individual channels of the colour model representations. The determination was performed using three smartphones followed by a comparison of the outcomes with spectrophotometric measurements. The most optimal analytical parameters were achieved for the H channel. The linear ranges obtained for the smartphone-based method proved to be comparable to the spectrophotometric range of 0.044–1.500 g dm−3 and were 0.049–1.500 g dm−3, 0.057–1.500 g dm−3, and 0.040–1.500 g dm−3 for Smartphones 1–3, respectively. Moreover, the determined coefficients of variance (CV, n = 9) and limits of detection (LOD) were 2.3% and 0.015 g dm−3, 6.2% and 0.017 g dm−3, and 2.5% and 0.012 g dm−3, respectively. Whereas for spectrophotometry, the obtained precision, CV was of 0.9% and a LOD of 0.013 g dm−3. The accuracy of the method was verified using model samples, generally the results were obtained with accuracy better than 10.9% (relative error). The method was applied to the determination of vancomycin in drugs. The results obtained by smartphone-based colorimetry did not differ from the expected values for more than 2.6%, were consistent with each other and with the results of spectrophotometric determinations.

“…1, resembles dopamine; however, as a selective agonist, its actions are mediated mostly by activating a and b receptors. 16 Dbn.HCl can be determined by a number of analytical techniques, including adsorptive stripping voltammetry, 14 high-performance liquid chromatography with either electrochemical 17 or CL 15 detection, spectrophotometry, 18 spectrouorimetry, 19 and a few CL-based methods. 20,21 Nevertheless, these methods oen suffer from one or more drawbacks, such as high cost, tedious and timeconsuming procedures, low sensitivity or narrow working range, the use of toxic or volatile organic solvents and/or reagents, and lack of selectivity.…”
