At the current state of development of chemistry, it appears easier to synthesize a compound
with a definite chemical structure than with a certain required property. Usually, reaction …

Sample pretreatment is the most important procedure to remove the matrix for interfacing
with mass spectrometry (MS). Additionally, for the samples with low concentration, the …

The aim of this research was to develop a simple and efficient ion-pair reagent-free
chromatographic method for the separation and qualitative determination of oligonucleotide …

A new type of bonded stationary phase for liquid chromatography, with the properties of
immobilized artificial membranes, has been synthesized. Alkyl-phosphate adsorbents were …

An extensive survey of the properties and separation capabilities of a cholesterol bonded
