Water is one of the most abundant compounds found in nature. An estimated 1.4 billion cubic kilometers of water exists on Earth and it covers 70% of our planets surface. Water is also a key element to life and makes up 70% of the fat-free mass of the human body. It is not surprising then that water is used, to at least some extent, in nearly all industries, and to quite a significant extent in most. The need to analyze water for contaminants, as well as its life-supporting characteristics, is nearly as wide.
