Environment

In environmental monitoring and analysis, standard are used as calibration materials for analytical methods and analytical instruments. Certain physical property values or component content values are determined according to specified accuracy and precision. They have acceptable uniformity and stability over a considerable period of time and are close to those of environmental samples in composition and properties.
