    • In a gas scavenging unit for gas chromatography analysis of gas generated in a thermal analyzer, the thermal analyser is equipped with a gas scavenging unit for scavenging gas generated in the thermal analyzer without usage of a carrier gas and no influence of a switching valve exists in the case of multi-stage sampling. For scavenging, there can be provided multiple sampling flow paths each have an aperture placed between the sample and the carrier gas outlet of the thermal analyzer, a flow regulator, a flow path switching valve, and a suction unit which is connected to the switching valve. The gas generated in the thermal analyzer is suctioned by the suction unit through a sampling flow path which is changed with the flow path switching valve. The appropriate volume of gas is scavenged to the GC analysis without any influence of the flow (rate) of the carrier gas even when the scavenging is done through switching to multiple scavengers.
    • 在用于气体色谱分析的气体清除单元中,在热分析仪中产生的气体,热分析仪配备有气体清除单元,用于清除在热分析仪中产生的气体,而不使用载气,并且不存在切换阀的影响 多级采样的情况。 为了清理,可以提供多个采样流程路径,每个采样流程路径都放置在热分析仪的样品和载气出口之间,流量调节器,流路切换阀和连接到开关阀的抽吸单元 。 在热分析器中产生的气体由抽吸单元通过采用流路切换阀改变的取样流路吸引。 即使当通过切换到多个清除剂进行清除时,将适当体积的气体清除到GC分析,而不影响载气的流量(速率)。
