Abstract

A gas analyzer includes: a gas measuring portion which performs a measurement on a gas; a case which houses the gas measuring portion; a liquid separator which includes a reservoir for storing a liquid component separated from the gas; a holder portion which holds the liquid separator; and a rotation mechanism which mounts the holder portion to the case.

Claims

1. A gas analyzer comprising:

a gas measuring portion which performs a measurement on a gas;

a case which houses the gas measuring portion;

a liquid separator which includes a reservoir for storing a liquid component separated from the gas;

a holder portion which holds the liquid separator; and

a rotation mechanism which mounts the holder portion to the case.

2. The gas analyzer according to claim 1, wherein further comprising:

a locking unit which locks the holder portion in a case where the holder portion is rotated to a position where the reservoir is in a lowermost portion in a direction of gravitational force in the liquid separator.

3. The gas analyzer according to claim 1, further comprising:

a sensor which detects an attitude of the holder portion with respect to a direction of gravitational force.

4. The gas analyzer according to claim 3, further comprising:

an alarm unit which generates an alarm in a case where the attitude of the holder portion which is detected by the sensor is not in a predetermined attitude in which the reservoir is positioned in the lowermost portion in the direction of gravitational force in the liquid separator.

5. The gas analyzer according to claim 3, further comprising:

a transmitting unit which transmits a detection signal in a case where the attitude of the holder portion which is detected by the sensor is not in a predetermined attitude in which the reservoir is positioned in the lowermost portion in the direction of gravitational force in the liquid separator.

6. A gas analyzer comprising:

a gas measuring portion which performs a measurement on a gas;

a case which houses the gas measuring portion;

a holder portion that holds a liquid separator which includes a reservoir for storing a liquid component separated from the gas, and which guides the gas from which the liquid component is separated, to the gas measuring portion; and

a holding unit which holds the liquid separator in one of attitudes which are different from one another in steps of 90 degrees.

7. The gas analyzer according to claim 6, wherein the holding unit includes a main flow path through which the gas is flown from the liquid separator to the gas measuring portion, and sub flow paths for applying a sucking operation on the reservoir.

8. The gas analyzer according to claim 7, wherein, in a face of the holder portion which is opposed to the liquid separator, a flow path port of the main flow path, and sub flow path ports of the sub flow paths are formed, the sub flow path ports being symmetrically placed about the flow path port of the main flow path.

9. The gas analyzer according to claim 6, further comprising:

a sensor which detects an attitude of the liquid separator held by the holder portion with respect to a direction of gravitational force.

10. The gas analyzer according to claim 9, further comprising:

an alarm unit which generates an alarm in a case where the attitude of the liquid separator detected by the sensor is not in a predetermined attitude in which the reservoir is positioned in the lowermost portion in the direction of gravitational force in the liquid separator.

11. The gas analyzer according to claim 9, further comprising:

a transmitting unit which transmits a detection signal in a case where the attitude of the liquid separator which is detected by the sensor is not in a predetermined attitude in which the reservoir is positioned in the lowermost portion in the direction of gravitational force in the liquid separator.
