퓨리에 트랜스폼 적외선 분석계

Process liquid analyzers such as pH meters, conductivity meters, ORP meters, and density meters play an important role at electrolysis plants in the control of concentrations of various process solutions. This requires both precision and stability under harsh conditions that include highly corrosive substances, high temperatures, and many impurities.

For the management of raw materials in the pharmaceutical and cosmetics industries, a manual titration method presents many difficulties. Yokogawa developed the NR800 FT-NIR Analyzer, and with this system, measurements are reliable and stable. It is much easier to control quality.

Loek van Eijck, Yokogawa, The Netherlands, questions whether rapid analysis of gases and liquids can be better achieved through use of a gas chromatograph or near infrared analyser. Conventionally, the liquid and gas components such as those broken down by naphtha crackers have been measured by a process gas chromatograph (PGC), with the subsequent measurement values then being used for control purposes.
