The use of water is vital to the manufacturing of semiconductors and electronics. In addition to the extremely high water quality requirements of the manufacturing process, a host of toxic materials and chemicals are used in the fabrication process, ranging from arsenic to harsh acids, will be present in the wastewater effluent.

Online monitors or offline analyzers can be used in semiconductor and electronics industries to obtain real-time data on trace metal contaminants in wafer and etching baths and to monitor rinse water for inorganic contaminants; ensuring regulatory compliance.
