Abstract

In cell culture, the pH of culture liquid is one of the most important conditions. However, culture liquid may have pH-gradient due to the activity of cells and change of the environment. In order to confirm the existence of pH-gradient, we propose a method for 3D pH measurement using the color change of phenol red. Using the principle of CT scan, we can measure pH-gradient without contacting culture liquid, and thus, decrease the possibility of contamination. In this paper, we consider the influence of light refraction by a cylindrical vessel, and show that we can measure local pH of culture liquid by light absorbance.
