Claims

[Scope of Claim for Utility Model Registration] (1) Multiple sample lines are integrated into one common line, and this common line, sampling pump, and separation column are connected to a gas sampler, and one
Let the sample gas flow from the main sample line and block the other sample lines,
By driving the sampling pump,
After cleaning the sample line, common line, and gas sampler, the gas sampler and sampling pump are shut off, and the sample gas is automatically analyzed by sending the sample gas and the gas sampler to a separation column. In the apparatus, when a forced cleaning line is branched to each of the sample lines and each line is washed by flowing sample gas from one sample line, the forced cleaning line can forcefully clean residual gas in other sample lines. An automatic gas analyzer characterized by: (2) The automatic gas analyzer according to claim 1, wherein the forced cleaning line includes a cleaning line branching from each sample line and a cleaning pump. (3) In the above-mentioned utility model registration request, the forced cleaning line is composed of a cleaning line branching from each of the sample lines and an aggregation line that aggregates the cleaning lines and is connected to a three-way valve provided in the common line. The automatic gas analyzer according to scope 1.
