[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 science that deals with the properties of organic and inorganic substances and their interactions with other organic and inorganic substances. In the study of matter, chemistry also investigates the movement of electrons. Because of the diversity of matter, which is mostly composed of different combinations of atoms, chemists often study how atoms of different chemical elements interact to form molecules and how molecules interact with each other.
