Quantitation of quinapril in human plasma by matrix-assisted laser desorption ionization time-of-flight mass spectrometry with quinolone matrix additives.
J. Chromatogr. B. Analyt. Technol. Biomed. Life Sci. 879(26) , 2688-94, (2011) The renin-angiotensin-aldosterone system (RAAS) is an essential body fluid maintenance system that controls pressure in the human body. The conversion of angiotensin I to angiotensin II by angiotensin-converting enzyme (ACE) is a key process in the RAAS becau... |

Adsorption of four perfluorinated acids on non ion exchange polymer sorbents.
Water Sci. Technol. 63(10) , 2106-13, (2011) Perfluorinated compounds (PFCs) have attracted global concern due to their ubiquitous distribution and properties of persistence, bio accumulation and toxicity. The process of adsorption has been identified as an effective technique to remove PFCs in water. D... |

Cooperative effect in ion pairing of oligolysine with heptafluorobutyric acid in reversed-phase chromatography.
J. Chromatogr. A. 1218(43) , 7765-70, (2011) The retention behavior of an oligolysine mixture, consisting of two to eight residues, was examined at different concentrations of heptafluorobutyric acid (HFBA) in the mobile phase using a C18 column. A single ion record (SIR) mode of the mass spectrometer p... |
