[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.
Chemistry is the branch of science that deals with the properties, composition and the structure of matter. It also deals with chemical reactions, changes in matter, and the pâ¦rinciples which govern these changes. Lighting a fire, making ice cream, and riding in a hot air balloon all deal with chemistry.
