Quantitative Structure-Retention Relationships Applied to Reversed-Phase High-Perfromance Liquid Chromatography
      
A brief summary of the theoretical background of QSRR is followed by presentation of reversed-phase high performance liquid chromatographic (RP-HPLC) separation theories of applications to the reported QSRR.
      
Two new trichothecenes, Roridin P and Isororidin P, and two known trichothecenes, Verrucarin A and Verrucarin J, were isolated from liquid cultures of Myrothecium roridum Tale ex Fr.
      
A sensitive high-performance liquid chromatography (HPLC) method was established for the determination of concentration of 5-FU-1-acetic acid in the gastrointestinal contents and plasma of rats.
      
This article demonstrates the use of a linear programming model to achieve an optimal allocation of liquid funds among various currencies in different countries.
      
In this paper, a method has been established and validated for screening and identification of individual as well as total BFA by high-performance liquid chromatography and liquid chromatography/electrospray mass spectrometry in fungal raw materials.
      
Column packing materials are always a key factor influencing the development of high-performance liquid chromatography (HPLC).
      
Liquid-Phase Hydrogenation of Chloronitrobenzene Over Pt-Sn-B Amorphous Catalyst Supported by Carbon Nanotubes
      
Its catalytic performance was evaluated by liquid-phase hydrogenation of chloronitrobenzene (CNB).
      
Analytical results for two batches of compound ibuprofen tablets by the SEKI-based FI-CE approach were in good agreement with that obtained by a conventional high performance liquid chromatographic method.
      
The annealed films of the polymers display characteristic nematic liquid crystalline texture.
      
In this paper, high performance liquid chromatography (HPLC) along with mass spectrometry (MS) and HPLC along with a diode array detector (DAD) was used to study the compound Ilex pubescens extract.
      
The liquid chromatograms obtained by DAD, total ion chromatograms (TIC) from positive-and negative-ion ESI-MS and the positive-and negative-ion APCI-MS were compared.
      
The liquid chromatograms obtained by TIC from ESI-MS provided more information on chromatographic peaks than those obtained by DAD or TIC from APCI-MS.
      
It is suggested that the fingerprints of the compound Ilex pubescens extract should be provided by the liquid chromatograms obtained by DAD together with TIC from the negative-ion ESI-MS.
      
In the liquid chromatogram obtained by TIC from the negative-ion ESI-MS, the molecular weights of 23 main components were determined based on the corresponding positive-and negative-ion ESI mass spectra information.
      
Rosin glycerin ester and its bromide were prepared from natural renewable rosin, glycerin and liquid bromine which were first subjected to an esterification reaction, followed by an addition reaction.
      
It has been found that rectificative phenomena exist only in the atmosphere-liquid interface region by means of liquid adsorption, and electric field could help form the oriented molecular film.
      
Studies on the properties of ionic liquid BMIInCl4
      
An ionic liquid (IL) was prepared by directly mixing InCl3 and 1-methyl-3-butylimidazolium chloride(BMIC) with molar ratio 1:1 under dry argon atmosphere.
