Abstract
A degassing deviceincludes: a built-in absorbance measurement sectionusing an LED light source and measuring the intensity of light transmitted through a mobile phase passing through a flow cell; and a solenoid valveswitchable between two states with and without the mobile phase passed through a degassing tube. The passage-switching operation by the solenoid valve is performed so as to obtain detection signals of the transmitted light in the absorbance measurement section when the mobile phase drawn from a mobile phase container by a liquid-feeding pumpis passed through the degassing tube for degassing as well as when the mobile phase is not passed through the degassing tube for degassing. A signal processorcalculates the difference in absorbance based on those detection signals, estimates the degree of degassing based on that difference, and displays the result on a display unit
