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.
