Abstract

PURPOSE:To facilitate transport, maintenance and the like of the device by integrating or individually separating a gas production means, a gas feed means and a column. CONSTITUTION:A gas production means 1 is provided with a cylindrical vessel 4, a cover 5 screwed thereto and detachably mounted thereon and a pressure crush body 6 and the like movably screwed up to the lower end part of the vessel 4. A gas feed means 2 is equipped with a cylindrically formed syringe 12 and a piston 13 whose outer circumferential face is slidably moved on the inner circumferential face of the syringe 12. A check valve 17 is provided between the syringe 12 and the vessel 4, an end part thereof is inserted in a receiving cylinder 14, another end part thereof is put in an exhaust cylinder 11 and each detachably mounted guide pipe 18 is provided. A column 3 is extended on the upper end part, a pipe 19 is provided and extended and a detachably mounted joint cylinder 20 is set between the pipe 19 and the syringe 12. In the case where each appliance is separated, the guide pipe 18 is detached from the exhaust cylinder 11 and the receiving cylinder 14, the joint cylinder 20 is rotated, detached from the syringe 12 of one hand and the other end part is extended and detached from the pipe 19 for the purpose of simply performing the separation.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas treatment device.

[0002]

2. Description of the Related Art A gas generator, a gas feeder, a column, etc., which are components of a gas analyzer for analyzing gas, are integrally formed.

[0003]

[Problems to be Solved by the Invention] However, the above means is inconvenient for transportation and storage.

[0004]

The present invention provides a gas treatment device for improving workability, and has taken the following technical means. That is, the gas processing device has a configuration in which the gas generating tool 1, the gas feeding tool 2, and the column 3 are integrally or separably provided.

[0005]

When the gas generator 1, the gas feeder 2 and the column 3 are assembled, they become integrated, and when they are disassembled, they are individually separated.

[0006]

[Effect] Since the gas treatment device can be integrated or separated individually, it can be easily transported and stored.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. First, the structure will be described. The gas generator 1 includes a hollow cylindrical container 4 having an open upper surface, and a lid 5 and a container 4 which are detachably provided by being screwed onto an outer peripheral surface of an upper end portion of the container 4. Crushing body 6 screwed so as to be movable to the lower end of the peripheral surface
And so on. A plurality of tapered projections 7 are provided on the lower surface of the crushed body 6, and a rod 8 having a longitudinal axis is provided at the center of the upper surface. The rod 8 is a lid 5.
A hole formed in the center of a silicon stopper 9 provided on the inner surface of the container for closing the container 4 is inserted and a handle 10 is provided on the upper end.
Is detachably installed. Further, the container 4 is provided with a discharge cylinder 11 that is located below the lower surface of the crush body 6 and communicates with the inside of the container 4 when the crush body 6 is located at the uppermost position.

The gas feeding device 2 is provided with a syringe 12 having a hollow cylindrical shape with its upper and lower ends opened, and a piston 13 whose outer peripheral surface can slide on the inner peripheral surface of the syringe 12. A receiving cylinder 14 is provided on the outer peripheral surface of the lower portion of the syringe 12, and the piston 12 has a syringe 12
16 which can be engaged with and disengaged from a flange 15 provided at the upper end of the
Is provided. A check valve 17 is provided at an intermediate portion between the syringe 12 and the container 4, one end of which is inserted into the receiving cylinder 14 and the other end of which is inserted into the discharge cylinder 11 so that the guides are detachable. A tube 18 is provided.

The column 3 has a pipe 19 extending from the upper end thereof. A detachable relay cylinder 20 is provided between the extension pipe 19 and the syringe 12. 21 is a relay cylinder 20
A silicon stopper provided at the tip of the column, and a head space gas introduction needle 22 that connects the relay cylinder 20 and the column 3 is provided at the center. 23 is a vaporization chamber, and 24 is a sample (for example, onion).

Next, the operation will be described. First, when the handle 10 is rotated, the crushing body 6 is moved downward in association with this, and when the predetermined position is reached, the rotation of the handle 10 is stopped. During this time, the projections 7 and the lower surface of the crushing body 6 crush the sample 24 to generate a head space gas. Then, when the piston 13 is pulled out to the outside, the head space gas generated in the container enters the syringe 12 through the discharge tube 11, the guide tube 18 and the receiving tube 14.

Subsequently, when the piston 13 is pushed inward, the back flow of the head space gas is blocked by the check valve 17, so that the head space gas enters the relay cylinder 20 from the syringe 12 and then passes through the head space gas introduction needle 22 to pass through the column 3. to go into. Further, the pushed piston 13 can prevent the recoil of hooking the hook 16 on the flange 15.

Then, when separating the respective devices, the guide tube 18 is removed from the discharge tube 11 and the receiving tube 14, and the relay tube 2
0 can be easily performed by rotating and removing from one syringe 12 and extending the other end and removing from the tube 19. Further, since the sample 24 is crushed in the state of being enclosed in the container 4 to generate the head space gas, gas loss can be prevented.
