Problems solved by technology

[0004] The direct cooling method cools the sample plate directly, so it has the advantage of a good temperature adjustment response speed, but on the other hand, it also has the problem that it is difficult to cool the sample plate uniformly because it is locally cooled from the lower surface side of the sample plate.

Embodiment Construction

[0025] Hereinafter, an embodiment of the sample temperature regulating device of the present invention will be described with reference to the drawings.

[0026] The sample temperature control device 1 includes a temperature control space 2 inside a metal plate 4 formed of a metal plate or the like. The outer peripheral surface of the metal plate 4 is also covered with a heat insulating layer 6 made of, for example, a polyethylene resin foam material, except for a heat radiation portion of the cooling unit 12 described below. That is, the cooling unit 12 is thermally separated from the outside air by the heat insulating layer 6 .

[0027] In the temperature control space 2 , a sample plate 10 holding a sample is installed in a state of being mounted on a rack 8 . The sample plate 10 may hold a plurality of vials containing samples, or may have a plurality of wells for containing samples on the upper surface. In this embodiment, the rack 8 on which the sample plate 10 is moun...

Abstract

This sample temperature adjustment device is provided with: a temperature adjustment space for adjusting the temperature of a sample by storing the sample therein; a heat insulating layer surroundingthe periphery of the temperature adjustment space so that the inside of the temperature adjustment space is thermally separated from the outside air; a cooling unit for cooling the inside of the temperature adjustment space; a heat transfer plate covering at least a part of the outer surface of the heat insulating layer; and a heater for heating the heat transfer plate so that dew condensation does not occur on the surface of the heat transfer plate.

Description

technical field [0001] The present invention relates to a sample temperature regulating device used in analysis devices such as liquid chromatography (liquid chromatograph) and used for cooling samples while regulating temperature. Background technique [0002] Among the auto samplers (auto samplers) of the liquid chromatograph, there are auto samplers that have the function of cooling the sample plate containing the sample and maintaining it at a constant temperature in order to prevent deterioration of the sample to be analyzed, etc. (For example, refer to Patent Document 1). In this application, devices such as automatic samplers with the function of temperature regulation of samples are collectively referred to as "sample temperature regulation devices". [0003] As the cooling and temperature adjustment method of the sample, as shown in Patent Document 1, the sample plate containing the sample is placed on a metal plate equipped with a cooling element such as a Peltier...
