El control del proceso papelero para maximizar la eficiencia de los aditivos qupimicos yace en el balance cuidadoso de las fuerzas coloidales e hidrodinámicas. Los métodos de caracterización de las cargas elécticas para los coloides de las pasta[...]Article : texto impreso
El mérito de la microelectroforesis es discutido a la luz de una reciente publicación que presenta datos altamente controversiales que impactan directamente sobre la credibilidad de esta técnica. La validez de las mediciones microelectroforética[...]texto impreso
RECIO, ISIDRA ; GARCÍA-RISCO, MÓNICA R. ; LOPEZ FANDIÑO, ROSINA ; RAMOS, MERCEDES ; OLANO, AGUSTÍN | 2000The fraudulent presence of rennet whey solids in UHT milk was studied by capillary electrophoresis (CE). Commercial UHT samples of different origins, genuine milk samples and milk samples adulterated with rennet whey were analysed. Linear discri[...]texto impreso
The presence of rennet whey solids in milk powder and buttermilk powder could be detected by analyzing the caseinomacropeptide (6.7 kDa) content by capillary zone electrophoresis. A hydrophilically coated capillary was used in combination with 6[...]texto impreso
