Development of Spectroscopic Technique using Capillary Flow Cells

*Professor of Department of Electronics and Informatics, Faculty of Science and Technology, Ryukoku University, Ph.D.in Engineering

Decreasing the diameter of the flow cell used for spectroscopic analysis allows for a smaller sample amount, faster response time, and higher sensitivity through a longer light path. Recently, a special type of optical fiber that traps light in gas or liquid, allowing efficient transmission of visible light or infrared light has been developed. A trend in spectroscopic measurement technology using such a capillary flow cell is introduced in this article.
