CHARACTERIZATION OF HUMIC ACIDS ORIGINATED FROM ARGENTINEAN COMPOST AND SOIL BY CAPILLARY ELECTROPHORESIS AND MASS SPECTROMETRY
(Sociedad Chilena de Química, 2005)
Modeling the Zeta Potential of Silica Capillaries in Relation to the Background Electrolyte Composition
(Wiley VCH Verlag, 2003-05)
A theoretical relation between the zeta potential of silica capillaries and the composition of the background electrolyte (BGE) is presented in order to be used in capillary zone electrophoresis (CZE). This relation is ...
Zoledronate and related impurities analysis by capillary zone electrophoresis
(Bentham Science Publishers, 2014-06)
A capillary zone electrophoretic (CZE) method has been developed for the determination of zoledronate and its related impurities (phosphyte and phosphate). Successful separation of the drug from the impurities was achieved ...
Direct detection of underivatized chitooligosaccharides produced through chitinase action using capillary zone electrophoresis
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008)
Capillary electrophoresis with capacitively coupled contactless conductivity detection was successfully used to quantify N-acetylglucosamine and five N-acetyl-chitooligosaccharides (C2-C6) produced after reaction with a ...
Fast separation of selective serotonin reuptake inhibitors antidepressants in plasma sample by nonaqueous capillary electrophoresis
(ELSEVIER SCIENCE BV, 2009)
A simple, fast, and sensitive liquid-liquid extraction method followed by nonaqueous capillary electrophoresis (LLE/NACE) was developed and validated for Simultaneous determination of four antidepressants (fluoxetine, ...
Determination of polyamines in organic extracts from roots of Canavalia ensiformis by capillary electrophoresis
(TAYLOR & FRANCIS INC, 2010)
A rapid, selective and specific capillary zone electrophoresis method to determine polyamines in organic extracts from roots of Canavalia ensiformis (Jack Beans) was developed using ultra violet (UV) detection. Canavalia ...
Capillary electrophoresis (CE): a powerful tool to characterize humic acid (HA)
(Sociedade Brasileira de Química, 2008)
The present study evaluates the possibility of eliminating the purification steps involved in the characterization of HA by capillary zone electrophoresis (CZE). The HAs of various sources were analyzed, showing different ...
Indirect determination of chloride and sulfate ions in alcohol fuel by capillary electrophoresis
A capillary zone electrophoresis method using indirect UV detection for the analysis of chloride and sulfate in alcohol fuel samples was developed. The anions were analyzed in less than 3 min using an electrolyte containing ...
Capillary electrophoresis to approach sorbate usage in processed meat products in Brazil
Sorbate is a highly used preservative in a wide range of processed foods, including meat products. In this work sorbate usage in commercial processed meat products from the Brazilian market was evaluated. A capillary ...
