Dmitrii Ivanovich Mendeleev and analytical chemistry

D. I. Mendeleev’s Concept of Chemical Elements and the Principles of Chemistry

Dmitrii Ivanovich Mendeleev (1834-1907) was primarily a chemist even though he later worked in many other fields. One of his most important contributions to chemistry was the discovery in 1869 of the periodic law of the chemical elements, which is still a fundamental concept in modern chemistry. In 1905, shortly before his death, he listed what he considered his four main contributions to scien...

Analytical Chemistry and Automation

INTRODUCTION To describe the relationship between analytical chemistry and automation is at the same time to describe the present position of both these fields, each of which strongly influences the other. We must give each its proper terms, and define the limits of their application. In so doing, we are considering not only the present position of analytical chemistry in its relationship to ot...

Analytical Chemistry Today and Tomorrow

Miniaturization in Analytical Chemistry

Miniaturization is rapidly growing, with novel ideas emerging in recent years. Like other fields, analytical systems have been affected by this new technology. Concretely, the capacity to carry out laboratory operations on a small scale using miniaturized devices is very appealing. Micro total analysis systems (mTAS), also called lab-on-a-chip, have renewed interest in scaling laws in the last ...

Chemometrics in Analytical Chemistry

Chemometrics is a scientific discipline closely connected with statistics and mathematics. It has an important role in analytical chemistry. Modern analytical methods provide opportunity to collect large amounts of data for various samples. For handling analytical results different chemometric methods are employed, such as basic statistical methods for the determination of mean and median value...
