The corner module has a support surface to support each corner portion of the rectangular thin panel from a lower side. At each corner portion, stacking the corner modules in a vertical direction stacks a plurality of rectangular thin panels in the vertical direction. The vibration suppressing bodies have a thickness equal to or less than the distance between the support surfaces of the corner modules vertically adjacent to one another; and are disposed on each of a top surface and an inferior surface of the rectangular thin panel such that the vibration suppressing body faces a planar portion of each rectangular thin panel to restrict vertical amplitude of vibration of the rectangular thin panel within a predetermined range.

Abstract: Nano-electrospray ionization techniques include the introduction of a separation solvent containing a sample to a column-integrated needle having a column filled with a resin for liquid chromatography. The separated sample components are sprayed from the tip of the column-integrated needle toward a sample introduction orifice of a mass spectrometer. An organic solvent is simultaneously introduced to a solvent-supplying needle. The organic solvent is supplied from the tip of the solvent-supplying needle to the tip of the column-integrated needle.

Abstract: It is an object of the present invention to improve the performance of gradient liquid transfer in nano/micro liquid chromatographs when solvents are mixed. In a gradient liquid transfer device and method for a nano/micro liquid chromatograph, an opening and closing unit (160) capable of opening and closing a solvent passage (150) for transferring a secondary solvent is provided in the vicinity of a solvent mixing section (152) in a liquid transfer system (130); a passage from a metering pump (146) of a liquid transfer section (142) to the opening and closing unit (160) is filled with the secondary solvent in advance; and an appropriate pressure is applied to the secondary solvent. Therefore, the entry of a primary solvent into the solvent passage for transferring the secondary solvent is suppressed.
