Total organic carbon measurements in the manufacturing or semiconductor industry are of big importance regarding product quality and safety in process. TOC levels in Ultra Pure Water (UPW) applications are very low.

Water in Manufacturing Industry

In the manufacturing industry, e.g. the semiconductor industry, numerous processes need ultra pure water for their operation. Any disturbance in water quality may lead to a cost intensive plant shut down - this should be avoided. Therefore, continuous and fast water analysis is required to meet the high quality standards set.
