摘要： A preparative separation-purification system has controlling apparatus, which has a pump housing for pumping liquid. The apparatus also has a moving component for reciprocating in the pump housing so as to draw a liquid into the pump housing and discharge the liquid from the pump housing and a driving source for reciprocating the moving component. A setting unit is provided for setting a target liquid supply amount or a target amount which corresponds thereto. A unit amount memory unit is provided for storing a discharge amount of the reciprocating pump per a reciprocal movement of the moving component or a unit amount which is a value corresponding to the discharge amount. A computation unit is provided for computing the smallest multiple number of the unit amount which is equal to or larger than the target amount; and a motor controller for controlling the driving source.

摘要： Provided is a mechanism for connecting columns and needles, including: a base member 60 on which needles 61a and 61b with their tips directed upward are provided; and a column rack 10 having column holders for holding columns 10a and 10b in an upright position while allowing all upward shift of the columns, with an opening provided below each column holder. With the needles 61a and 61b positioned directly below the openings, the base member 60 is elevated until its upper surface comes in contact with the bottom of the column rack 10, whereby the needles 61a and 61b are inserted through the openings into the columns 20a and 20b. When the base member 60 is in contact with the column rack 10, the columns 20a and 20b are pushed by the needles 61a and 61b to a higher position within the column rack 10 than their original position.

摘要： A degassing device 2 includes: a built-in absorbance measurement section 28 using an LED light source and measuring the intensity of light transmitted through a mobile phase passing through a flow cell; and a solenoid valve 26 switchable between two states with and without the mobile phase passed through a degassing tube 21. 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 pump 40 is 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 processor 29 calculates 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 32.

摘要： In a preparative separation-purification system for passing a solution containing a target component through a trap column to capture the target component in the column, and for subsequently passing an eluting solvent through the column to elute the captured component and collect it in a container, a dilution passage is merged with a collection passage for sending an eluate from the outlet end of the trap column to the collection container, and a diluting liquid is intermittently introduced through the dilution passage into the collection passage. The diluting liquid lowers the concentration of the target component in the eluate and impedes the deposition of the target component. Thus, clogging of the passage due to the deposition of the target component eluted from the trap column is effectively prevented.
