Objective: Nowadays, most pharmaceutical formulations contain more than one drug because there are numerous advantages to multicomponent formulations, like patient compliance, enhanced efficacy, synergetic effects of both drugs, etc. This review paper describes the simultaneous estimation methods such as UV spectroscopy and high-performance liquid chromatography (HPLC) to determine various drug molecules Read More

Background: In chemical and pharmaceutical analysis, hyphenated techniques range from the combinations involving separation-separation, separation-identification and identification-identification techniques and are widely used nowadays, as they hold many advantages like fast accurate analysis, a higher degree of automation, higher sample throughput, better reproducibility, specificity and sensitivity. They also Read More

Food preservatives are used to keep bacteria, moulds, fungus, and yeast from spoiling food. Food additives are subject to strict rules (particularly in the European Union - EU), which consider the food to which they can be applied, maximum permissible quantities, chemical characterization, and purity. Sorbic acid, mainly potassium sorbate, is primarily utilised in a variety of commercially available foods. Various analytical strategi Read More

Background: Nanoparticles based thin-film has remarkable challenges in water desalination. Carbon allotropes (carbon nanotubes, graphene sheets, and fullerene), metal and metal oxide nanoparticulates (titanium dioxide, silver, copper oxide, alumina, zinc oxide, and metal-organic framework, silica, halloysite, zeolite, aquaporin and cellulose) are the out breaking materials for water desalination. Advanced materials Read More

Objective: Inductively coupled plasma atomic emission spectroscopy (ICP/AES) has been used for the determination of phosphine residues in cereal and tissue biological samples. Methods: The method used is based on the reaction of phosphine residue with H2SO4 in a headspace vial, determining the phosphor of the liberated phosphine gas by ICP/AES at 213.6 nm. At this wavelength, there is a linear relationship betwe Read More

Aims: Understand the metabolic behavior of new psychoactive substances, furanyl fentanyl, TFMPP, and 5-MeO-DALT. Background: New psychoactive substances (NPS) are associated with several health and social harms on both the individual and societal levels. Many are not regulated and have become increasingly popular among drug users worldwide. The lack of clinical studies on the effects and toxicity of t Read More

Background: The use of modified electrochemical sensors is essential for the detection of antibiotic drug abuse. The main objective of this article is to develop a silk-derived carbon material for the modification of pyrolytic graphite electrodes (PGE) for the sensitive detection of chloramphenicol (CAP). Methods: We proposed a pyrolysis synthesis of porous carbon nanosheets (Fe-Silk PNC) using silk as a precursor. Properties of car Read More

Aim: The aim of this work is to fabricate pipette tip electrodes for the capillary electrophoretic determination of nicotine and phenolic compounds in tobacco. Background: The content of nicotine affects not only the quality of tobacco products but also the health of smokers. Phenolic compounds are important flavor precursors in tobacco. The quantity of phenolic compounds is one of the most important evaluation indicators of to Read More
