Abstract
Hispanic and Latinx scientists have made substantial contributions to science and technology, spanning a wide range of analytical chemistry fields. These outstanding research endeavors by individuals of Hispanic and Latinx heritage have not only advanced our understanding of scientific principles but also have led to pioneering breakthroughs that have improved human health and more generally our daily lives. For example, Mexican analytical chemist Dr. Mario Molina shared the 1995 Nobel Prize in Chemistry for research on understanding the mechanisms for how chlorofluorocarbon gases were affecting the ozone layer in the earth’s atmosphere. The innovation displayed by Hispanic and Latinx scientists such as Dr. Molina has been achieved despite facing systematic barriers and the challenges that come with being under-represented in science. Nevertheless, in the past, not all of the research achievements of Hispanics and Latinx scientists have been recognized. This has been changing slowly over the last couple of decades with help from various scientific organizations, especially ones dedicated to supporting underrepresented scientists such as the Society for the Advancement of Chicanos and Native Americans in Science (SACNAS) or the American Chemical Society’s Committee on Minority Affairs.

期刊介绍:
Analytical Chemistry, a peer-reviewed research journal, focuses on disseminating new and original knowledge across all branches of analytical chemistry. Fundamental articles may explore general principles of chemical measurement science and need not directly address existing or potential analytical methodology. They can be entirely theoretical or report experimental results. Contributions may cover various phases of analytical operations, including sampling, bioanalysis, electrochemistry, mass spectrometry, microscale and nanoscale systems, environmental analysis, separations, spectroscopy, chemical reactions and selectivity, instrumentation, imaging, surface analysis, and data processing. Papers discussing known analytical methods should present a significant, original application of the method, a notable improvement, or results on an important analyte.
