1. FUNDAMENTOS DE ELETROFORESE CAPILAR: UMA ABORDAGEM POR ANIMAÇÕES
Among the analytical separation techniques, capillary electrophoresis (CE) has attracted attention in both academic and industrial fields, mainly owing to its efficiency, short analysis times, low reagent consumption and residue generation. This is also the case in Chemistry courses, books and papers, demonstrating CE´s well-established status. However,

2. Estratégias de pré-concentração em eletroforese capilar (CE): parte 1. Manipulação da velocidade eletroforética do analito
Capillary electrophoresis has become a well-established and routine-based separation technique. It is based on the differences between charged analyte mobility in aqueous or organic electrolytes. Its major limitation is the sensitivity due to small sample injection volumes and the narrow diameter of the capillaries, especially when UV detection is used. Ther

3. Desenvolvimento de instrumentação para eletroforese capilar de zona e isotacoforese capilar em microdispositivos de toner-poliéster / Development of instrumentation for capillary zone electrophoresis and capillary isotachophoresis using toner-polyester microdevices
A eletroforese capilar em microchips (µCE ou MCE) é uma forma diferente de eletroforese capilar que tem se desenvolvido muito nos últimos anos. Essa técnica usa microdispositivos feitos em placas que podem ser de vidro ou polímero contendo canais de dimensões micrométricas ao invés de um capilar de sílica. Ganhos significativos têm sido obtidos em

4. Analysis of bacterial fermentation products by isotachophoresis.
Various carboxylic acids from bacterial fermentation could easily be separated by isotachophoresis. The analyses were performed on an LKB 2127 Tachophor, and under the conditions used the minimum amount of sample that could be quantitatively estimated was approximately 0.1 nmol. The reproducibility of the method was good (ca. 5 percent). The time of analysis

5. Gram-preparative protein fractionation by isotachophoresis: isolation of human growth hormone isohormones.
Steady-state stacking (isotachophoresis) provides a preparative method in zone electrophoresis for the isolation of proteins in gram amounts. Up to four components were separated in 1000-fold larger quantities than those used in conventional electrophoresis. Separation occurs in order of free electrophoretic mobility. Recovery is nearly quantitative. The met

6. Effects of rosuvastatin on electronegative LDL as characterized by capillary isotachophoresis: the ROSARY Study
Electronegative LDL, a charge-modified LDL (cm-LDL) subfraction that is more negatively charged than normal LDL, has been shown to be inflammatory. We previously showed that pravastatin and simvastatin reduced the electronegative LDL subfraction, fast-migrating LDL (fLDL), as analyzed by capillary isotachophoresis (cITP). The present study examined the effec

7. Formation of N,N-Dimethylglycine, Acetic Acid, and Butyric Acid from Betaine by Eubacterium limosum
Two bacterial strains that grow anaerobically on betaine were isolated from enrichment cultures and identified as strains of Eubacterium limosum. In a mineral medium supplemented with yeast extract and Casitone, the doubling time of E. limosum strain 11A on betaine was 6 h at 37°C. The molar growth yield amounted to 9 g of dry cell mass per mol. Betaine was

8. Extraction of Zinc from Industrial Waste by a Penicillium sp
Zinc was extracted from a filter residue of a copper works (58.6% zinc) by a Penicillium sp. isolated from a metal-containing location. By isotachophoresis citric acid was identified as the leaching agent. Citrate was only formed when the leaching substrate was present. This production of citrate was different in several ways from that achieved by Aspergillu
