[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.
In more formal terms chemistry is the study of matter and the changes it can undergo. Chemists sometimes refer to matter as âstuffâ, and indeed so it is. Matter is anything that has mass and occupies space. Which is to say, anything you can touch or hold.
