Abstract
A gas chromatograph device (100) includes a calculator (2) configured to acquire information on conduits (36) between a branch unit (33) and detectors (34) and information that identifies types of the detectors connected to the conduits, the calculator being configured to calculate at least one of gas flow rates in the conduits, gas linear velocities in the conduits, or a pressure in the branch unit based on the acquired information.
Claims7
A gas chromatograph device comprising:
- a sample introduction unit configured to send a carrier gas and a sample gas;
- a column configured to separate components of the sample gas introduced from the sample introduction unit;
- a branch unit provided downstream of the column where a conduit of the sample gas is branched into a plurality of branched conduits;
- a plurality of detectors connected to the branch unit;
- and
- a calculator configured to acquire;
- information on a connection of the plurality of branched conduits between the branch unit and the plurality of detectors;
- and
- information for identifying types of the plurality of detectors connected to the plurality of branched conduits,
- the calculator being configured to calculate at least one of;
- gas flow rates in the plurality of branched conduits,
- gas linear velocities in the plurality of branched conduits, or
- a pressure in the branch unit based on the acquired information,
- wherein the branch unit is connected to the plurality of detectors via a plurality of resistance tubes as the plurality of branched conduits and is configured to distribute the sample gas from the column to each of the plurality of resistance tubes, and
- wherein the calculator is further configured to calculate a branch ratio of a gas distributed to each of the plurality of resistance tubes connected to the plurality of detectors based on both information of the plurality of resistance tubes and information that identifies types of the plurality of detectors respectively connected to the plurality of resistance tubes.
An analysis support method for a gas chromatograph device comprising a branch unit provided downstream of a column configured to separate components of a sample gas introduced from a sample introduction unit where a conduit of the sample gas is branched into a plurality of branched conduits, and a plurality of detectors connected to the branch unit, the analysis support method comprising:
- acquiring information on a connection of the plurality of branched conduits between the branch unit and the plurality of detectors;
- and
- acquiring information for identifying types of the plurality of detectors connected to the plurality of branched conduits;
- and
- calculating at least one of:
- gas flow rates in the plurality of branched conduits,
- gas linear velocities in the plurality of branched conduits, or
- a pressure in the branch unit based on the acquired information,
- wherein the branch unit is connected to the plurality of detectors via a plurality of resistance tubes as the plurality of branched conduits, and
- wherein the analysis support method further comprises:
- distributing the sample gas from the column to each of the plurality of resistance tubes, and
- calculating a branch ratio of a gas distributed to each of the plurality of resistance tubes connected to the plurality of detectors based on both information of the plurality of resistance tubes and information that identifies types of the plurality of detectors respectively connected to the plurality of resistance tubes.
