AbstractThe selection and application of an array of piezoelectric sensors for assessing the state of respiratory organs in calves by the composition of the headspace of the exhaled condensate are discussed. We considered the relationship between the output recorded data, calculated data of the sensor array, and the state of the respiratory system ...

AbstractA simple, fast and efficient method based on ultrasound-assisted emulsification microextraction (USAEME) followed by HPLC has been developed for simultaneous determination of Carbamazepine (CBZ) and Lamotrigine (LTG) in biological samples. The influence of different parameters affecting the USAEME procedure was evaluated to optimize the eff...

AbstractWe studied the main electrode functions of carbon paste electrodes (CPEs) modified with 0–20% of dithiooxamidated polysiloxane with respect to palladium(II). The conditions for the potentiometric titration of palladium(II) using modified CPEs as indicator electrodes were selected, namely, pH 1–2, solutions of EDTA and potassium iodide as th...

AbstractA combined method of analysis of high-purity germanium dioxide by atomic emission spectrometry with matrix preseparation and trace element preconcentration was developed. The matrix was separated in an autoclave of a MARS 5 microwave system without the contact of samples with an acid solution. The method allows the determination of the foll...

AbstractWe present a method for the quantitative determination of the Agidol-1 antioxidant additive in fuels for jet engines in concentrations of 0.001–0.006 wt % by HPLC after its preconcentration by extraction with methanol. The ratio of fuel-to-methanol-to-water in extraction is optimized. Chromatographic separation was performed on a Kromasil C...

AbstractElectrochemical properties of regorafenib (REG) were studied in 0.1 M Britton−Robinson buffer-methanol solutions (3 : 2, v/v) with pH between 3 and 8 at carbon paste electrode by cyclic and differential pulse voltammetry. The results exhibited irreversible anodic peak at about 0.90 V vs. Ag/AgCl, NaCl (3 M). The anodic peak was found to be ...
