An automatic sample injection system (1) includes at least an injector (2). The injector (2) includes a turret (10) comprising a plurality of vial receiving holes (30) that are corresponding to a plurality of types of vials having different sizes, the plurality of vial receiving holes (30) being provided on the same circumference on an upper surface of the turret, the turret being configured to rotate so that the plurality of the vial receiving holes (30) are each moved along a circumferential track, and a controller (22) configured, in a case where a sampler (4) for supplying a vial to the injector (2) is provided, to recognize a size of a target vial to be supplied at the time when the target vial is supplied from the sampler (4) and to arrange the vial receiving hole (30) corresponding to the target vial at a delivery position (P) set on the circumferential track.

The present disclosure is applicable to the field of analytical instruments, and provides a multifunctional probe for sample pickup, delivery and electrospray ionization used for direct sample analysis with a liquid-phase mass spectrometer. The multifunctional probe comprises a needle body and a tip part, wherein said tip part is continuously contracted from the needle body in whole or in part, and said tip part is provided with a solution carrying structure. The present disclosure further provides a combined sample introduction and electrospray device for liquid-phase mass spectrometry comprising said multifunctional probe, further comprising a mechanical arm and an ion source with a sealed chamber and a needle port on the sealed chamber.

Methods and systems are provided for the identification of sample cells in a sample tray that is placed in a chromatography autosampler. A cell gripper and labels are also provided to facilitate such identification.

There are provided a sample cooling device capable of preventing air containing moisture from flowing into an accommodating chamber from outside the accommodating chamber, and of desirably dehumidifying air inside the accommodating chamber, and an autosampler provided with the same. Air is sent into an accommodating chamber 11 by a blower section 100 from outside the accommodating chamber 11 and the air is cooled by a dehumidifier section 13 to thereby cause dehumidified air to be supplied into the accommodating chamber 11. With the air sent into the accommodating chamber 11 by the blower section 100 from outside the accommodating chamber 11, the inside of the accommodating chamber 11 may be placed in a pressurized state. Since dehumidified air is supplied into the accommodating chamber 11 by air sent into the accommodating chamber 11 by the blower section 100 from outside the accommodating chamber 11 being cooled by the dehumidifier section 13, the humidity inside the accommodating chamber 11 may be prevented from rising due to the air that is sent from the blower section 100.

An apparatus for collecting liquid fractions from a separation/reaction apparatus (1). A capillary (2) guides an extracted liquid fraction to a branching unit (3), a collection arrangement (4) carries a plurality of target vessels (5) receiving the liquid fraction from the capillary and a fluid line (6) is flow-connected to a fluid pump (7) and opens into the branching unit. The capillary and the fluid line each have outlet openings in the direct vicinity of one another at their end facing a target vessel such that liquid emerging from the outlet opening (2′) of the capillary transitions into the outlet opening (6′) of the fluid line. This precludes back mixing with earlier/later liquid fractions, precludes uncontrolled dripping of sample substance at the transfer point, speeds displacement of the target vessels in the collection arrangement, facilitates automation of the fraction processing procedure, and results in a more compact fraction collection apparatus.

A control method for an automatic analyzer that can improve robustness, throughput, and measurement accuracy. The automatic analyzer includes a sample loop connected between two sample ports of a plurality of sample ports of a switch valve. The method includes the steps of: adjusting a drive parameter of the syringe corresponding to a viscosity of the sample acquired in advance; switching the switch valve to a first state in which the sipper and the syringe contact with each other without through the sample loop; driving the syringe based on the drive parameter to draw and introduce the sample through the sipper; switching the switch valve to a second state in which the syringe and the sample loop conduct with each other; and driving the syringe based on the drive parameter to introduce the sample into the sample loop.

A chromatographic data system processing apparatus includes a liquid feeder, a sample injector, a column that separates samples, a detector, a controller that processes a detected result of the detector, and a data processor that examines and sets operations of the liquid feeder, the column and the detector, and a measurement condition. The data processor generates a three-dimensional graph having three axes related to a pressure, a time, and a number of theoretical plates based on data or variables indicating a relationship between the number of theoretical plates and a flow rate, and data or variables indicating a relationship between the pressure and the flow rate. The chromatographic data system processing apparatus can easily obtain a separation condition for obtaining performance from a three-dimensional graph including a pressure drop, a hold-up time and a number of theoretical plates.
