## Abstract

Provided is an apparatus for extracting, analyzing, and storing gas in a drilled core on a ship. The apparatus includes: a needle for core insertion inserted into the drilled core to allow the gas in the drilled core to the outside; and a first 3-way valve into which the gas passing through the needle for core insertion is introduced and which controls the introduced gas so as to be supplied to a gas storing container or gas analyzing apparatuses positioned on a ship

## Claims

### Claim 1

An apparatus for extracting, analyzing, and storing gas in a drilled core secured through ocean exploration on a ship by supplying the gas to gas analyzing apparatuses 2a and 2b, the apparatus comprising:
the needle 10 for core insertion inserted into the drilled core 1 to allow the gas in the drilled core 1 to be discharged to the outside; and
the first 3-way valve 30 into which the gas passing through the needle 10 for core insertion is introduced and which controls the introduced gas so as to be supplied to a gas storing container 20 or gas analyzing apparatuses 2a and 2b positioned on a ship.

### Claim 2 (depends on 1)

The apparatus of claim 1, further comprising a pressure controlling valve 40 allowing the gas to be discharged at pressure in a predetermined range when the gas is discharged to the first 3-way valve 30 through the needle 10 for core insertion.

### Claim 3 (depends on 1)

The apparatus of claim 1, wherein a gas introduction hole 11 formed so that the gas in the drilled core 1 is introduced thereinto in order to be discharged to the outside is formed at a side of the needle 10 for core insertion.

### Claim 4 (depends on 1)

The apparatus of claim 1, further comprising the second 3-way valve 50 allowing the gas passing through the needle 10 for core insertion to be supplied to the first 3-way valve 30 or to be discharged to the outside.

### Claim 5 (depends on 1)

The apparatus of claim 1, further comprising an analysis channel determining unit 60 allowing the gas passing through the first 3-way valve 30 to be supplied to a predetermined gas analyzing apparatus 2a or 2b among a plurality of gas analyzing apparatuses 2a and 2b.

### Claim 6 (depends on 2)

The apparatus of claim 2, wherein a gas introduction hole 11 formed so that the gas in the drilled core 1 is introduced thereinto in order to be discharged to the outside is formed at a side of the needle 10 for core insertion.

### Claim 7 (depends on 2)

The apparatus of claim 2, further comprising the second 3-way valve 50 allowing the gas passing through the needle 10 for core insertion to be supplied to the first 3-way valve 30 or to be discharged to the outside.

### Claim 8 (depends on 2)

The apparatus of claim 2, further comprising an analysis channel determining unit 60 allowing the gas passing through the first 3-way valve 30 to be supplied to a predetermined gas analyzing apparatus 2a or 2b among a plurality of gas analyzing apparatuses 2a and 2b.
