In this work, a revisit to the retention mechanism of HILIC was attempted to point out critical factors that contribute to the chromatographic regime as well as to bring out subtle details of the relative contribution of partitioning and surface adso

Four polar compounds, i.e. pantothenic acid, inositol, taurine and caffeine were used as probe solutes in conjunction with chemometric methods to find out meaningful implications of chromatographic conditions and detector settings on the system perfo

Headspace microextraction has already been established as the method of choice for analyzing volatiles blended in complex matrices, such as environmental, food and biological samples. The modern trend of analytical chemistry for 'going small' has led

An effort has been made to investigate the chromatographic behavior and to understand the basic mechanisms in HILIC-based separation of water-soluble vitamins with highly varied properties on a diol column. The water content of the mobile phase is of

Microwave-assisted phase-transfer catalysis (PTC) is reported for the first time, for the one-step extraction-derivatization-preconcentration and gas chromatographic determination of twenty phenols and ten phenolic acids. The well established phase-t

The aerial parts of Hypericum perforatum L were studied to assess their composition in basic categories of bioactive compounds and their antioxidant activity, employing commonly accepted assays. The results reveal that floral buds, during the develop

The environmental fate of phenols represents a diachronic scientific consideration mainly due to their high toxicity and diverse physicochemical properties rendering them difficult to be analyzed as unity. Ion-pair-assisted extraction and microextrac

A suitable method for the gas chromatographic determination of 10 characteristic carbonyls in biological and oil samples based on the in-drop formation of hydrazones by using 2,4,6-trichlorophenylhydrazine (TCPH), has been developed. The derivatisati

A novel in-drop derivatisation liquid-phase microextraction procedure with an ion-pairing agent is developed and optimised for the extraction of endocrine-disrupting chemicals. The ethyl esters of the analytes were rapidly formed in the organic drop

In-drop derivatisation single-drop microextraction approach can constitute, to a certain degree, a low-cost reasonable alternative to the well-known on-fibre solid-phase microextraction. The headspace mode integrates extraction, preconcentration and
