AbstractA simple and an available method is proposed for the determination of quinolone antibiotics using solid-phase fluorescence digital colorimetry. The intrinsic fluorescence of 17 quinolones and the quinolone-sensitizedfluorescence of europium on cellulose paper (CP) and a thin silica layer are studied. Upon the irradiation of quinolone soluti...

AbstractWe proposed a method for the rapid assessment of the state of adverse processes in gynecological patients, using highly volatile compounds of an invasive biological test (cervical mucus), which makes it possible to assess the patient’s gynecological status in real time in a doctor’s office. A highly sensitive detector based on seven mass-se...

AbstractA simple and precise RP-HPLC method has been developed and validated for the separation and trace determination of selected food colorant residues, namely, Tartrazine (E102), Sunset Yellow (E110) and Allura Red (E129), in water samples. The colorants were separated in less than five minutes using buffered distilled water as a mobile phase o...

AbstractA procedure is developed for the separate determination of the Sn(II) and Sn(IV) in the range of 0.05–0.25 M in acidic aqueous and ethylene glycol solutions in the presence of Ni(II), Cu(II), F–, a surfactant (OS-20), and citric or oxalic acids. The direct iodatometric titration of Sn(II) is used before and after the reduction of Sn(IV) wit...

AbstractThe electrochemical sensor was developed based on electrodeposition of chitosan/copper nanoparticles (CT-nano Cu) on the electrode modified with N, P, S co-doped porous carbon (N, P, [email protected]). Scanning electron microscopy image has shown that nano Cu in CT-nano Cu/N, P, [email protected] composite is uniform with an average size of about 70 nm. CT-nano Cu/...

AbstractIn this study, the idea of sample-specific metabolites library with retention neighbor was presented for better identification and quantitation of metabolites. Compared with universal libraries, the established library was found to have significantly improved match indices (similarity, reverse, and probability), indicating better identifica...

AbstractWe demonstrated a possibility of using a chemical sensor array for the control of the formation of the aroma of confectionery masses during conching. The correlation between the results of sensor-metric analysis and physical and chemical indicators of the quality of confectionery masses was evaluated. An array of chemical sensors enables th...

AbstractLipstick smear analysis can provide valuable information in forensic investigations, but it is difficult to distinguish lipstick products because their complex compositions can vary with the brand and product. In this study, various lipstick samples were analyzed using time-of-flight secondary ion mass spectrometry (ToF-SIMS) and attenuated...

AbstractTwo methods are proposed for assessing the total concentration (cAr) of the most toxic hydrocarbons (arenes) in wastewaters. The procedures include the extraction of petroleum products with n-hexane, the adsorption purification of the extract from phenols, and the measurement of the absorbance of arenes in the UV region. No separation of al...

AbstractThe current state of scientific and practical results of the application of polycapillary (multichannel) systems to various areas of analytical chemistry is considered. Polycapillary systems consist of a matrix of single capillaries, which can have different geometries and sizes (from 10 nm to n × 102 µm). They are made of various materials...
