In recent years, the biotechnology field has entered a new stage. In the pharmaceutical field, in particular, the development of new biopharmaceuticals is accelerating using cell culture technology, represented by ES cells and iPS cells, along with genome analysis technology. The management of each measurement item, including pH and dissolved oxygen, is essential for its development. In bioprocesses, pharmaceutical water is widely used for cleaning water such as manufacturing equipment, and the required specifications vary depending on the process. HORIBA contributes to all processes, from R&D to on-line measurement to support high-quality and high-efficiency production and post-use wastewater monitoring.
