Analytical chemistry studies and uses instruments and methods to separate, identify, and quantify matter. In practice, separation, identification or quantification may constitute the entire analysis or be combined with another method. Separation isolates analytes. Qualitative analysis identifies analytes, while quantitative analysis determines the numerical amount or concentration.
The conservation and restoration of cultural property focuses on protection and care of cultural property, including artworks, architecture, archaeology, and museum collections. Conservation activities include preventive conservation, examination, documentation, research, treatment, and education. This field is closely allied with conservation science, curators and registrars.
Mass spectrometry (MS), also called mass spec, is an analytical technique that is used to measure the mass-to-charge ratio of ions. The results are presented as a mass spectrum, a plot of intensity as a function of the mass-to-charge ratio. Mass spectrometry is used in many different fields and is applied to pure samples as well as complex mixtures.
Gas chromatography–mass spectrometry (GC–MS) is an analytical method that combines the features of gas-chromatography and mass spectrometry to identify different substances within a test sample. Applications of GC–MS include drug detection, fire investigation, environmental analysis, explosives investigation, food and flavor analysis, and identification of unknown samples, including that of material samples obtained from planet Mars during probe missions as early as the 1970s. GC–MS can also be used in airport security to detect substances in luggage or on human beings. Additionally, it can identify trace elements in materials that were previously thought to have disintegrated beyond identification. Like liquid chromatography–mass spectrometry, it allows analysis and detection even of tiny amounts of a substance.
The history of mass spectrometry has its roots in physical and chemical studies regarding the nature of matter. The study of gas discharges in the mid 19th century led to the discovery of anode and cathode rays, which turned out to be positive ions and electrons. Improved capabilities in the separation of these positive ions enabled the discovery of stable isotopes of the elements. The first such discovery was with the element neon, which was shown by mass spectrometry to have at least two stable isotopes: 20Ne and 22Ne. Mass spectrometers were used in the Manhattan Project for the separation of isotopes of uranium necessary to create the atomic bomb.
The Association of Biomolecular Resource Facilities (ABRF) is dedicated to advancing core and research biotechnology laboratories through research, communication, and education. ABRF members include over 2000 scientists representing 340 different core laboratories in 41 countries, including those in industry, government, academic and research institutions.
Smithsonian Libraries and Archives is an institutional archives and library system comprising 21 branch libraries serving the various Smithsonian Institution museums and research centers. The Libraries and Archives serve Smithsonian Institution staff as well as the scholarly community and general public with information and reference support. Its collections number nearly 3 million volumes including 50,000 rare books and manuscripts.
Pittcon Editors’ Awards honoured the best new products on show at the Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy, or Pittcon, for 20 years from 1996 having been established by Dr Gordon Wilkinson, managing editor of Analytical Instrument Industry Report. On 8 March 2015, the event returned to the Morial Convention Center in New Orleans and this was the last occasion when the awards were presented.
The Chemical Research Center of the Hungarian Academy of Sciences is a non-profit research institute seated in Budapest, Hungary.
The Smithsonian Institution's Museum Support Center (MSC) is a collections storage and conservation facility in Suitland, Maryland which houses Smithsonian collections which are not on display in the museums. It is not usually open to the public, due to security concerns, though occasionally special tours are organized.
Instrumental analysis is a field of analytical chemistry that investigates analytes using scientific instruments.
The Rathgen Research Laboratory is a Research Institute of the Berlin State Museums under the auspices of the Prussian Cultural Heritage Foundation. It carries out cross-material conservation science, art technology and archaeometry studies of fine arts and cultural artifacts to determine composition, age and authenticity and provide advice on their restoration. It further conducts academic research on scientific issues concerning the care and preservation of monuments and archaeological sites. Founded in 1888 as the Chemical Laboratory of the Royal Museums in Berlin, it is the oldest museum laboratory in world and bears the name of its first director, Dr. Friedrich Rathgen.
A conservation scientist is a museum professional who works in the field of conservation science and whose focus is on the research of cultural heritage through scientific inquiry. Conservation scientists conduct applied scientific research and techniques to determine the material, chemical, and technical aspects of cultural heritage. The technical information conservation scientists gather is then used by conservator and curators to decide the most suitable conservation treatments for the examined object and/or adds to our knowledge about the object by providing answers about the material composition, fabrication, authenticity, and previous restoration treatments.
Kliti Grice, is a chemist and geochemist known for her work in identifying geological and environmental causes for mass extinction events. Her research integrates geological information with data on molecular fossils and their stable carbon, hydrogen and sulfur isotopic compositions to reconstruct details of microbial, fungal and floral inhabitants of modern and ancient aquatic environments and biodiversity hot spots. This information expands our understanding of both the Earth's history and its current physical state, with implications ranging from energy and mineral resource exploration strategies to environmental sustainability encompassing climate dynamics and expected rates, durations and scale of our future planet's health. As one of the youngest women professors in Earth Sciences, she is the founding director of the Western Australian Organic and Isotope Geochemistry Centre (WA-OIGC) and is a Professor of Organic and Isotope Geochemistry at Curtin University in Perth, Western Australia.
Conservation and restoration at the Smithsonian Institution deals with the care of the 138 million artifacts located in the collections of Smithsonian Institution. Work is conducted by one research center, the Museum Conservation Institute (MCI), and by conservators at the Smithsonian's museums, galleries, zoo. Smithsonian conservators provide myriad services to their units, including exhibit preparation of the museum collection and loan objects, advising on object care, training for future generations of conservationists, engaging in routine preventive care on a daily basis, conducting research projects related to the collections, and examining objects for evidence of manufacturing techniques and previous restorations All conservation labs collectively further the mission of the Smithsonian Institution, "the increase and diffusion of knowledge." Founded in 1846 the Smithsonian is the world's largest museum and research complex, consisting of 19 museums and galleries, the National Zoological Park, and nine research facilities.
French national institute of cultural heritage, called Institut national du patrimoine (Inp), is the only academy in France in charge of the training of both curators and conservators. It belongs to French Ministry of Culture and is organized in 2 departments.
Ron M.A. Heeren is a Dutch scientist in mass spectrometry imaging. He is currently a distinguished professor at Maastricht University and the scientific director of the Multimodal Molecular Imaging Institute (M4I), where he heads the division of Imaging Mass Spectrometry.
