质谱气体分析仪 

    质谱气体分析仪  PMA1000,并已申请了两项 国家发明专利(公开号分别为101144795,101144794)。该分析仪可以 同时、快速、准确地测定钢铁、合金、铜、锆、钛、钼、镍、陶瓷和其他无机物中多种气体元素的含量。

       采用惰气做载气, 利用位于脉冲加热炉上下两个电极之间的石墨坩埚瞬间高达3000℃的特性,使样品 在其中被加热熔融。样品中氧化物和氮化物与C发生还原应,生成 CO 和N2。HAr以H2 和Ar形式释放。载气将 反应释放的混合气体CO、N2,H2,Ar载入飞行时间质谱 检测器,不同质量数的离子飞行时间不同,根据被分离的不同离子信息最终得到样品中O,N,H,Ar的含量。

      PMA 1000 pulse heating-MS gas analyzer has been developed by Beijing NCS analytical instruments Co.,Ltd. recently. Based on the techniquetwo patents have been applied in China (Publication No. 101144795 and 101144794 ). The analyzer is designed for the simultaneousrapid and accurate determination of gas elements in steelironalloyscopperzirconiumtitaniummolybdenumnickelceramics and other inorganic materials.

    Inert gas is adopted as the carrier gas. The sample is heated and fused in the graphite cruciblewhich is placed between the upper and lower electrodes of the pulsed heating furnace and can be heated to 3000 °C instantly. Redox reactions take place in the sample with C. CO and N2 are generated from the reaction. HAr in the sample are released in form of H2 and Ar. The mixed gases are carried into the TOF-MS detector by the carrier gas. Flying time of ions with different mass are different. The content of ONHAr can be got by the information of these ions.
