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.
Clinical chemistry is a division in medical laboratory sciences focusing on qualitative tests of important compounds, referred to as analytes or markers, in bodily fluids and tissues using analytical techniques and specialized instruments. This interdisciplinary field includes knowledge from medicine, biology, chemistry, biomedical engineering, informatics, and an applied form of biochemistry.
Harvey Washington Wiley was an American chemist who advocated successfully for the passage of the landmark Pure Food and Drug Act of 1906 and subsequently worked at the Good Housekeeping Institute laboratories. He was the first commissioner of the United States Food and Drug Administration.
Agilent Technologies, Inc. is an American global company headquartered in Santa Clara, California, that provides instruments, software, services, and consumables for laboratories. Agilent was established in 1999 as a spin-off from Hewlett-Packard. The resulting IPO of Agilent stock was the largest in the history of Silicon Valley at the time. From 1999 to 2014, the company produced optics, semiconductors, EDA software and test and measurement equipment for electronics; that division was spun off to form Keysight. Since then, the company has continued to expand into pharmaceutical, diagnostics & clinical, and academia & government (research) markets.
A drug test is a technical analysis of a biological specimen, for example urine, hair, blood, breath, sweat, or oral fluid/saliva—to determine the presence or absence of specified parent drugs or their metabolites. Major applications of drug testing include detection of the presence of performance enhancing steroids in sport, employers and parole/probation officers screening for drugs prohibited by law and police officers testing for the presence and concentration of alcohol (ethanol) in the blood commonly referred to as BAC. BAC tests are typically administered via a breathalyzer while urinalysis is used for the vast majority of drug testing in sports and the workplace. Numerous other methods with varying degrees of accuracy, sensitivity, and detection periods exist.
Forensic chemistry is the application of chemistry and its subfield, forensic toxicology, in a legal setting. A forensic chemist can assist in the identification of unknown materials found at a crime scene. Specialists in this field have a wide array of methods and instruments to help identify unknown substances. These include high-performance liquid chromatography, gas chromatography-mass spectrometry, atomic absorption spectroscopy, Fourier transform infrared spectroscopy, and thin layer chromatography. The range of different methods is important due to the destructive nature of some instruments and the number of possible unknown substances that can be found at a scene. Forensic chemists prefer using nondestructive methods first, to preserve evidence and to determine which destructive methods will produce the best results.
The Centre of Forensic Sciences (CFS) is a laboratory providing forensic science services to law enforcement agencies in Ontario, Canada. It is part of the government of Ontario Ministry of Solicitor General public safety division.
The Health Sciences Authority (HSA) is a statutory board under the Ministry of Health of the Government of Singapore. It is a multi-disciplinary agency responsible for applying medical, pharmaceutical, and scientific expertise to protect and advance public health and safety.
Public Analysts are scientists in the British Isles whose principal task is to ensure the safety and correct description of food by testing for compliance with legislation. Most Public Analysts are also Agricultural Analysts who carry out similar work on animal feedingstuffs and fertilisers. Nowadays this includes checking that the food labelling is accurate. They also test drinking water, and may carry out chemical and biological tests on other consumer products. While much of the work is done by other scientists and technicians in the laboratory, the Public Analyst has legal responsibility for the accuracy of the work and the validity of any opinion expressed on the results reported. The UK-based Association of Public Analysts includes members with similar roles if different titles in other countries.
Laboratory Corporation of America Holdings (Labcorp), headquartered in Burlington, North Carolina, provides laboratory services used for diagnosis and healthcare decisions. It operates one of the largest clinical laboratory networks in the world and has operations in over 100 countries; although its operations are primarily in the U.S.
The Connecticut Agricultural Experiment Station (CAES) is the Connecticut state government's agricultural experiment station, a state government component that engages in scientific research and public outreach in agriculture and related fields. It is the oldest state experiment station in the United States, having been founded in 1875. Its official mission is to "develop, advance, and disseminate scientific knowledge, improve agricultural productivity and environmental quality, protect plants, and enhance human health and well-being through research for the benefit of Connecticut residents and the nation." The station operates a main research campus in New Haven, a research farm in Hamden, a satellite research facility and farm in Windsor, and a research farm in Griswold. The Storrs Agricultural Experiment Station is a separate agricultural research agency, founded in 1887 and part of the University of Connecticut, which also receives state and federal funding.
Forensic metrology is a branch of metrology applied to forensic sciences. Metrology has evolved various techniques for assessing the margin of error or uncertainty associated with measurements. Forensic laboratories and criminalistic laboratories perform numerous measurements and tests to support criminal prosecution and civil legal actions. Examples of forensic metrology include the measurement of alcohol content in blood using breathalyzers, quantification of controlled substances, and length measurements of firearm barrels. The results of forensic measurements are used to determine if a person is charged with a crime or may be used to determine a statutory sentencing enhancement. Other examples of forensic metrology includes tests that measure if there is a presence of a substance, latent print examination, questioned documents examination, and DNA analysis.
Hach Company manufactures and distributes analytical instruments and reagents used to test the quality of water and other liquid solutions. Manufactured and distributed worldwide, Hach systems are designed to simplify analysis by offering on-line instrumentation, portable laboratory equipment, prepared reagents, easy-to-follow methods, and technical support.
Radiometer is a Danish multinational company which develops, manufactures and markets solutions for blood sampling, blood gas analysis, transcutaneous monitoring, immunoassay testing and the related IT management systems. The company was founded in 1935 in Copenhagen, Denmark by Børge Aagaard Nielsen and Carl Schrøder. It has over 3,200 employees and direct representation in more than 32 countries. Corporate headquarters remain in Copenhagen.
Nuclear forensics is the investigation of nuclear materials to find evidence for the source, the trafficking, and the enrichment of the material. The material can be recovered from various sources including dust from the vicinity of a nuclear facility, or from the radioactive debris following a nuclear explosion.
