Embodiment Construction

[0052] The manner in which the invention can be carried out is explained below with the aid of embodiments.

[0053] figure 1 is a configuration diagram of a plate-like column according to one embodiment of the present invention. The plate-like column 10 has a rectangular main body 11 and a first protrusion 12 and a second protrusion 13 protruding from one side of the main body 11 . Both the first protrusion 12 and the second protrusion 13 are smaller than the main body 11 in width.

[0054] The main body 11 , the first protrusion 12 and the second protrusion 13 are composed of two stainless steel substrates (hereinafter referred to as an upper substrate 17 and a lower substrate 18 ) having a thickness of 0.3 mm laminated on each other. The main body 11 has a length of 10 cm and a width of 10 cm. Each of the first protrusion 12 and the second protrusion 13 has a length of 3 cm-8 cm and a width of 0.6 cm.

[0055]The plate column 10 has an internal flow path 14 having a wi...

Abstract

Provided is a plate-type column which allows the temperature of its inner passage to be rapidly increased or decreased while ensuring the correctness of an analysis or other operations. A plate-type column 10 includes: a plate-shaped main body 11; projecting portions 12 and 13 protruding from a circumferential edge of the main body 11; and a fluid-flow passage 14 extending in the main body 11 and the projecting portions 12 and 13. An intermediate portion of the passage 14 is provided in the main body 11, while each of the end portions of the passage 14 extends from the main body 11 through the projecting portion 12 or 13, with each of the end portions being open to the outside at the tip of the projecting portion 12 or 13.

Description

technical field [0001] The present invention relates to a plate-shaped column having a flow path through which a fluid (gas or liquid) flows to separate components in the fluid introduced into the flow path, to analyze these components so that they undergo a certain type of reaction, or to use for other purposes. The present invention also relates to a temperature regulation system for performing temperature regulation of the plate-shaped column and a gas chromatography system having the plate-shaped column and the temperature regulation system. Background technique [0002] In recent years, gas chromatography systems have been widely used to separate and / or analyze components in gaseous samples. Two types of columns are generally used in gas chromatography systems, namely packed columns and capillary columns, packed columns consist of stainless steel tubes or glass tubes filled with a stationary phase, and capillary columns consist of quartz tubes coated with a stationary ...
