摘要： In order to be able to prevent analysis accuracy from being reduced by a backward flow of sample gas from dead volume in a cleaning mechanism into a cell at the time of analysis, a gas analysis device has an analysis part that analyzes the sample gas introduced into the cell, gas ports that are arranged toward predetermined regions of gas contact surfaces in the cell, and a piping mechanism that connects the gas ports to a predetermined purge gas source, and blows purge gas from the gas ports toward the predetermined regions at the time of purging. The gas analysis device also has a switching part that switches a connecting destination of the piping mechanism from the purge gas source to a predetermined suction part, and at the time of introducing or analyzing the sample gas, connects the gas ports to the suction source.
摘要翻译：为了能够防止在分析时将样品气体从清洁机构的死体积向单元中的反向流动减少的分析精度，气体分析装置具有分析部件，其分析导入的样品气体电池单元中的气体接触表面的预定区域设置的气体端口，以及将气体端口连接到预定的吹扫气体源的管道机构，并且在该时间将吹扫气体从气体端口吹向预定区域清洗。气体分析装置还具有将管道机构的连接目的地从吹扫气体源切换到规定的吸入部的切换部，在引入或分析样品气体时，将气体端口与吸入源连接。
