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 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 chemists study wheat and grains. Their work is very varied – some analyse the biochemistry of wheat and grain while others focus on improving and maintaining crop yields. This type of work is used in the agricultural industry.
Inorganic chemists research the behaviour and properties of inorganic compounds. They often use thermodynamic principles to determine the properties of these compounds. This type of chemistry is applicable to almost all other types of chemistry.
Material chemists focus on synthesising and designing new materials. The often study the organisation of molecules in order to do this. This type of work has many applications such as cosmetics, drug delivery and electronic materials.
Many research teams will involve different types of chemists working together. This is because each scientist will have their own knowledge and skill set; some will be specialised in a certain type of chemistry, have expertise in certain machinery, or past experience that is pertinent to the experiment being undertaken.
Therefore, through collaboration, the team as a whole gains a wider base of knowledge.

...The steps of this experiment have been ordered with this in mind.
Measuring the pH and the turbidity are both quick, non-destructive tests, therefore they are performed first. The TDS and the DO can be measured destructively or non-destructively, however in this experiment they are measured through non-destructive methods.
Once the non-destructive tests are completed, the only destructive test with a time limit is the test for BOD; it is preferable performed within 2 hours of the sample being collected and must be performed within 24 hours of collection. This test also takes the longest amount of time to complete (5 days). Because of this, it is logical to perform the test for BOD next.
The tests for heavy metals and hardness are both destructive, though neither have a time limit that must be adhered to. Therefore, they are the last tests to be completed.

Characteristic of Organic Compounds Essay

- What are organic compounds, you may ask. Well organic compounds are compounds that always contain carbon, or any compound that contains a carbon atom. But some describe organic compounds as any of a large class of chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly are hydrogen, oxygen, and nitrogen. But there are a few exceptions to this organic rule, which are carbon monoxide, carbonates, carbon dioxide, cyanides, cyanates, carbides, and thyocyanates, which are all considered inorganic....   [tags: Carbon Atoms, Chemical Compounds]

Essay on Understanding the Way Atoms Connect Together to form Compounds

- The whole world is made up of Chemical and Physical bonds and one of the greatest advancements in history is understanding the way atoms connect together to form compounds. In chemical bonding there are two types of bonds that are called Ionic and Covalent bonds. Ionic bonds form when an electrical attraction between two oppositely charged atoms or groups of atoms called Ions. Covalent bonds form when one or more electrons are transferred from one atom to another. Atoms either share pairs of electrons between them or transfer one or more electrons from one atom to another....   [tags: compounds, chemical bonding, atoms]

Covalent and Ionic Compounds Essay

- Compounds are pure substances that contain atoms of two or more elements chemically combined in fixed ratios. In this lab, we observed two types of compounds, Ionic compounds and Covalent compounds. Ionic compounds are chemical compounds consisting of two or more ions that are held adjacent to each other by electrical attraction. “One of the ions, called an “anion,” has a negative charge, and the other is called a “cation,” and has a positive charge. “Cations” are usually metallic atoms and “anions” are either atoms of nonmetals or polyatomic ions....   [tags: chamical analysis]

Analytical Chemistry is the Study of the Separation, Identification, and Quantification of Chemical Components

- Analytical chemistry may be defined as the study of separation, identification, and the quantification of the chemical components of natural and artificial materials1 constituted of one or more substances. Analytical chemistry is divided in to two main types, qualitative analysis that is to say the identification of the chemical species present the sample, and quantitative analysis determines the amount of certain element or compound in the substance i.e., sample. Pharmaceutical analysis1-3 plays a vital role today and can be considered as an interdisciplinary subject....   [tags: physical properties, pharmaceutical, investigation]

The Chemical Corps Regiment Essay

- The Chemical Corps Regiment The US Army Chemical Corps history began back in World War I as the Chemical Warfare Service. World War I came to be known as the “Chemists War” because of the first uses of chemical warfare agents (Fitzgerald, 2008). The use of chemical agents by Germany was said to have been initiated by the necessity of war fighters to develop new war strategies to offset trench warfare. German armies were complacent with trench warfare and could no longer rely on this method to ensure victory (Blodgett, 2009)....   [tags: US army, chemical warfare]

Exploring the Role of Chemists Essay

- Exploring the Role of Chemists It was Lavoisier who divided the few elements known in the 1700's into four classes, and then John Dalton made atoms even more convincing, suggesting that the mass of an atom was it's most important property. In the nineteenth century Johann Döbereiner was the first to attempt to classify elements using their relative atomic mass. He also identified a number of ‘triads’ in the list of elements then known. Each triad was a set of 3 elements that have similar properties (e.g....   [tags: Papers]
