自动化氮吹仪是利用氮气的快速流动打破液体上空的气液平衡，从而使液体挥发速度加快，并通过水浴加热方式升高温度，从而达到样品快速浓缩的目的；采用一定纯度的氮气作吹扫，可以隔绝空气，防止目标物氧化，还可以保持样品的纯净，防止引入其他杂质。所以，对于氮吹仪来说，很重要的一部分就是供气系统和气路控制系统。

自动化氮吹仪供气系统选配有氮气钢瓶、氮气发生器，有以下7个方面因素对比氮气发生器和氮气瓶。

1、实验室安全

  • 氮气钢瓶需要在高度70%-80%处进行固定，否则容易倾倒伤到实验人员。
  • 使用氮气钢瓶，实验室需要制订处理钢瓶泄露的预案，否则后果不堪设想。
  • 数量限制：国际上的相关防火协会（NFPA和IFC）对规定区域内的最大可燃物数量都有相关限制。若选择氮气瓶，实验室内有数量限制，需要专人专管。
  • 实验室安全方面，以上都是氮气钢瓶安全方面需要注意的地方，氮气发生器无需固定位置、带有滑轮随时挪动；安装氮气发生器时候，确保正确连接和固定气管和阀门，就可以很好的避免气体泄漏。氮气发生器产气量按需供应，1台足以提供氮气源。

2、操作是否简便：氮气发生器操作简单，只需一个简单的开关，即可启动。相比之下，使用氮气钢瓶需要更复杂的连接接口和安全操作。

3、节约人力成本：氮气钢瓶需要专人专管，负责定期更换氮气钢瓶，检查是否气体泄漏现象。氮气发生器无需专人看，节省人力成本。

4、节约经济成本：自动化氮吹仪一般24～100位数不等，手动氮吹装置一般最多24位，位数相比手动氮吹多得多，需要氮气用量更大，氮气发生器免去了更换氮气瓶的繁琐，长远考虑，费用成本更低。

5、实验结果的平行性：氮气发生器相比氮气罐供气更加稳定，能够持续稳定供气，并且吹扫样品的气量一致，样品平行性更好。

6、是否持续、稳定供气：氮气发生器可以持续并稳定的提供氮气，不需要更换气瓶。相比之下，氮气瓶有限的容量需要定期更换，避免中途因为气瓶用尽导致实验中断或者不连续供气的情况。

7、占地面积：对于实验室面积有限情况下，氮气钢瓶用于氮吹至少备4-5瓶，占地面积大；一体式氮气发生器，可置于实验室桌下，占地面积小。

综上所述，氮气发生器作为自动化氮吹仪的辅助设备，更具安全性、操作简单方便、节省人力和经济成本，持续稳定供气，保证实验结果的稳定性。
