Water in which impurities such as inorganic ions and organic substances remain are expressed in mg / L (ppm) or less, and is referred to as pure water. Water which is further purified is expressed in units of ppb, ppt and is referred to as ultra pure water.For example, Type1 / A4 level pure water can cover all applications from Type1 to Type4 (ASTM D 1193) / A1 to A4 (JIS K 0557) levels.Yamato Scientific's water purifier is designed to produce Type1 / A4 level of both distilled water and deionized water. Meanwhile, models which can produce higher-level ultra pure water such as TOC reduction water and pyrogen-reduced water are also available.
