[A]rm's length has generally been defined to mean that there are no bonds of dependence, control or influence, between the corporation and the person in question.. In MNR v Sheldon, Justice Esson of Canada's Supreme Court wrote:
Analytical chemistry focuses on the chemical composition and function of matter. Analytical chemists are concerned with reaction rates and levels of chemicals in different types of matter. For example, an analytical chemist might test a patient's blood to investigate how a medication is working.
Organic chemistry is the scientific study of the structure, properties, composition, reactions, and synthesis of organic compounds that by definition contain carbon. It is a specific discipline within the subject of chemistry. Organic compounds are molecules composed of carbon and hydrogen, and may contain any number of other elements. Many organic compounds contain nitrogen, oxygen, halogens, and more rarely phosphorus or sulphur. Current trends in organic chemistry are chiral synthesis, green chemistry, microwave chemistry and fullerene chemistry.
