实时在线分析是质谱仪器得以广泛应用的一个重要领域。成功的分析不仅取决于质谱计本身的优越性能，而且取决于所使用真空系统及进样系统的很好配合．本文着重描述了羽毛蒸煮过程中释放气体的成功实时分析和分析所用的单极质谱计及其真空、进样系统．真空系统包括机械泵、离子泵、高真空阀门、超高真空阀门、热偶规、电离规及连接管道．这些部件都是被小型化的。进样系统包括可以控制加热到２００℃的进样毛细管道和分子漏孔．
Real-time online analysis is an important area where mass spectrometry instruments are widely used. Successful analysis depends not only on the superior performance of the mass spectrometer itself, but also on the good fit of the vacuum system and injection system used. This article highlights the unipolar mass spectrometer and its vacuum, injection system used for successful real-time analysis and analysis of the released gas during feather cooking. Vacuum systems include mechanical pumps, ion pumps, high vacuum valves, ultrahigh vacuum valves, thermocouple gauges, ionization gauges and connecting lines. These parts are miniaturized. The injection system includes injection capillary tubes and molecular leaks that can be controlled to 200 ° C.
