1. Desenvolvimento, avaliação e aplicação de um sistema de cromatografia gasosa de alta pressão / Development, implementation and evaluation of a system of high pressure gas chromatography
A cromatografia é uma técnica de separação cuja classificação se dá por meio do estado físico da fase móvel (líquido, gasoso, supercrítico, entre outros). Dentre as técnicas cromatográficas mais utilizadas e cujo conhecimento é bastante conhecido está a cromatografia gasosa. Embora esta técnica tenha sido bastante estudada existem ainda algum

2. Eletrocromatografia capilar: contextualização, estado da arte e perspectivas
Capillary electrochromatography (CEC) is a separation technique in which the mobile phase flow is based on the application of a voltage across a packed capillary, which generates an electroosmotic flow that transports the analytes along the capillary toward the detector. As it combines the separation mechanisms of high-performance liquid chromatography (HPLC

3. Determination of fatty acid compositions of Bacillus cereus and related bacteria: a rapid gas chromatographic method using a glass capillary column.
A rapid gas chromatographic method for the determination of fatty acid compositions of Bacillus cereus and related bacteria is presented. By the use of a free fatty acid phase-coated glass capillary column, the complete separation of fatty acids, including the branched ones, was achieved. The method enables a more distinct differentiation of Bacillus species

4. Aromatic and Volatile Acid Intermediates Observed during Anaerobic Metabolism of Lignin-Derived Oligomers
Anaerobic enrichment cultures acclimated for 2 years to use a 14C-labeled, lignin-derived substrate with a molecular weight of 600 as a sole source of carbon were characterized by capillary and packed column gas chromatography. After acclimation, several of the active methanogenic consortia were inhibited with 2-bromoethanesulfonic acid, which suppressed met
