英国Hiden公司生产的CATLAB催化剂表征系统,由两部分组成:催化微反应器和气体分析质谱(Microreactor-Mass Spectrometers)。
CATLAB可以进行催化反应,吸附剂在反应器中,通过通入不同的反应气体(如氢气、氦气、氮气等)得到不同的反应结果。逸出气体由质谱(QGA)进行检测,以得出反应情况。然后通过软件分析得到实验结果。气体的流量通过软件设置。
质谱QGA,质量数1~200amu,可以进行大多数的气体检测。可以单独使用,也可以与其他仪器连接,进行逸出气体分析。
·快速响应,低热量损失炉子
·*的可互换的催化剂套管系统
·底座热电偶,直接测量催化剂温度
·质谱与反应器连接紧密,无死体积,方便蒸气分析
·操作软件自动控制仪器,同步获得、显示质谱数据
·抗腐蚀管路结构(选配)
· 1~20 ℃/min 加热速率,至1000℃
·每一通道,独立的质量流量控制为3~100 ml/min,500ml/min为选配
·质量数1~200amu(300amu选配)
·进样响应时间小于500ms
·定量数据输出PPM, PPB 或 %单位
·快速扫描100amu/s,用于瞬时分析
·自动/手动操作4气流管路(可选配至8路)
