Pure substances are devoid of contaminates or impurities. Like that other person said, elements are theoretically the most pure, fundamental, basic substance; however, a compound can be pure as well if it has no impurities mixed in. You could also argue that a mixture of NaCl and water is pure if you were searching for a pure saline solution. Your question is a bit vague!
