Analytical Chemists and Chemical Compounds Essay - 1511 Words

Analytical chemists will use different types of analysis to identify chemical compounds and their properties. Some tests they may use to conduct this analysis include calorimetry, spectroscopy and chromatography. This type of workis used in a wide variety of industries such as mining and metal production industries. Environmental Environmental chemists investigate chemical phenomena in nature and the human effects on these. They use many of the same tests as analytical chemists to accomplish this. This type of work is often used in conjunction with environmental engineers. Cereal Cereal chemists study wheat and grains. Their work is very varied – some analyse the biochemistry of wheat and grain while others focus on improving and†¦show more content†¦Bridgeman is interested in probing the relationship between quantum theory and these concepts. He has developed software to calculate chemical connectivity from the beginning and a graphical device to detect delocalized and hypervalent interactions. Name Deanna DAlessandro Workplace ARC QEII Fellow at the University of Sydney Branch Inorganic and Material Qualifications BSc (Hons I Medal), James Cook University, 2000 PhD (cum laude), James Cook University, 2005 Chemical principle Microporous Conductors: Her work involves the design and synthesis of purely organic and metal-organic frameworks that demonstrate the property of redox-activity (i.e. electronic conductivity). The new materials will be based on ligands and mixed-valence metal clusters of Mo, W, Ru and Os, and others. Solid-state electrochemical and spectroelectrochemical techniques will be developed to investigate the conductivity properties. The potential applications range from sensors to molecular electronics devices. Atomic Absorption Spectroscopy Atomic absorption spectroscopy (AAS) is a technique used in the analysis of many elements, particularly metals. To do this, first a solution containing the example to be analysed is sprayed into a flame, creating a vapour of atoms. A light beam is passed throughShow MoreRelatedThe Six Branches Of Chemistry1482 Words   |  6 Pages and preparation of chemical compounds that consist primarily of carbon and hydrogen. organic chemistry the study of most carbon containing compounds INORGANIC CHEMISTRY Inorganic chemistry is the study of the properties and behaviour of inorganic compounds. It covers all chemical compounds except organic compounds. Inorganic chemists study things such as crystal structures, minerals, metals, catalysts, and most elements in the Periodic Table.

There are many fields one can specialize in such as analytical, biological, inorganic, organic, or physical chemistry. Chemists also have a good variety of workplaces such as laboratories, hospitals, private companies, government agencies, or colleges and universities.

Dyes and medicines were other early products obtained from natural substances. Some practical applications that chemistry is used for are to make stronger metals, improve soil, and the developments of live-saving drugs. Modern technology depen ds highly on these advancements; chemistry is a way of explaining our material world. Many people cant understand the importance of chemistry if they arent planning on being a chemist. What manyRead MoreInvestigating The Substances Of Water Chromatography1350 Words   |  6 PagesMost chemists and many other scientists must routinely separate mixtures and identify their components. The ability to qualitatively identify the substances found in a sample can be critical. For example, an environmental chemist investigating samples of polluted ground water will want to know which toxic ions might be present in a sample. Chromatography is one of the first tools used in such situations. In this technique, many types of mixtures can be separated into the component pure substances;Read MoreForensic Techniques Used By Investigators1622 Words   |  7 PagesFingerprint testing was one of the original forensic techniques used by investigators. The use of fingerprinting, however, has becom e less important due to technological innovations such as DNA analysis. Nonetheless Shin Muramoto and Edward Sisco chemist at the National Institute of Standards and Technology are changing that, once again looking to innovation to make fingerprint analysis a state of the art technique. They are doing this by examining how Palmitic acid moves in fingerprints, allowingRead MoreBrief Historical Development and Contributions of Chemistry for Modern Civilization4507 Words   |  19 Pagesanother by a chemical reaction. A complex substance can by made from simpler ones. Chemical compounds can break down into simpler substances. Fuels burn, food cooks, leaves turn in the fall, cells grow, medicines cure. Chemistry is concerned with the essential processes that make these changes happen. Brief Historical Development: Chemistry plays an important part in all of the other natural sciences, basic and applied. From the earliest recorded times, humans have observed chemical changes andRead MoreImpacts of Applications of Chemistry on Society and the Environment3915 Words   |  16 Pageslevel of chemical endeavor of that time.

Even though the O2 calculations in mg/L and dissolved oxygen measured by a DO meter varied, they both had similar trends. Interpretation: Australian water authorities such as SEQ Water, employ numerous chemical engineers, environmental scientists and analytical chemists to maintain the quality of water in our waterways such as the Brisbane river. This ensures that water is safe for use by humans and organisms within the natural ecosystem. The results gained from this investigation indicate
