La Química Analítica es un área de la ciencia con gran impacto en la vida cotidiana. Es una disciplina genérica y su desarrollo posibilita grandes avances en muchas áreas como la Medicina, Biotecnología, Ciencia de los Materiales, Ciencia Forense, Ingeniería, Medio Ambiente, Tecnología de los Alimentos, etc. De ahí, que actualmente, se considera que el objeto de la Química Analítica es toda la materia. En este contexto, el objetivo principal de esta obra es que el alumno entienda la importancia actual de la Química Analítica y la forma en que se trabaja, a través de la realización de experimentos prácticos relacionados con el análisis de muestras orgánicas e inorgánicas mediante el uso de instrumentos analíticos modernos. Se pretende pues, motivar el interés del alumno por el análisis químico moderno. Además, puesto que las prácticas de laboratorio han sido siempre una herramienta básica para el aprendizaje de la Química, otros objetivos básicos de esta obra son que el alumno se familiarice con el material de un laboratorio de Análisis instrumentales más importantes y que sepa aplicar estos conocimientos para la resolución de problemas analíticos sencillos.

Es insólito que siendo la química analítica la ciencia de la medida química, estén tan descuidadas las bases en las que ésta se asienta y tan infrautilizadas las potencialidades que ofrecen diversas tecnicas quimiometricas de trabajo. El presente manual plantea y discute esas bases de una forma sistematica: arranca con una rapida ojeada a los principios de la estadistica, para centrarse despues en algunas tecnicas del analisis multivariante, atendiendo a sus fundamentos y al proceso de transformacion al que se ven sometidos los datos experimentales en cada caso. El texto esta salpicado de numerosos ejercicios propios del campo de la quimica para ayudar a la comprension de los fundamentos y obligar a discurrir sobre el amplio abanico de posibilidades y aplicaciones que ofrecen los metodos quimiometricos, a menudo infravalorados por el analista. Carlos Mongay Fernandez es doctor en Ciencias Quimicas y catedratico de Quimica Analitica en la Universitat de Valencia desde hace mas de 20 años. En la actualidad es director del Departamento de Quimica Analitica. Ha publicado numerosos articulos en revistas nacionales e internacionales y ha impartido el curso de doctorado de Quimiometria como consecuencia del cual nacio la necesidad de profundizar en este area y propagar la disciplina en el vasto contexto de la quimica analitica.
