  • Publication number: 20240192181
    Abstract: A chromatograph allows easy replacement of a separation column while preventing an operator from contacting with a configuration related to the separation column. A column cartridge accommodates the separation column and is detachably provided in a predetermined column installation position. An upstream pipe is detachably provided on the column cartridge in a state of being installed at the column installation position, and supplies a mobile phase to the separation column of the column cartridge. A downstream pipe is detachably provided on the column cartridge in a state of being installed at the column installation position, and delivers the mobile phase that has passed through the separation column of the column cartridge. A cover integrally covers the column installation position, the upstream pipe, and the downstream pipe and has an insertion hole that allows the column cartridge to be installed from the outer side of the cover.

  • Publication number: 20240168405
    Abstract: Rotation of an image bearing member is started and stopped in a contact state between the image bearing member and a developing member. During post-rotation operation, a controller ends application of a charging voltage after changing the charging voltage stepwise to first and second charging voltages. The controller ends application of a developing voltage after changing the developing voltage stepwise at a developing position to first and second developing voltage in synchronism with the first and second charging voltages. A potential difference between each of surface potentials of first and second regions and an associated one of the first and second developing voltages is maintained within a predetermined range. The controller carries out control so that an absolute value of the surface potential of at least one of the first and second regions is made small by passing a current under application of a transfer voltage.
