氦检测器是一种结构简单,而对永久性气体(如 N_2、O_2、Ar、H_2、CO、CO_2等)具有极高灵敏度的一种气谱仪上应用的探测器,它除了 Ne 以外,几乎对所有永久性气体全能测定。它的*小探测量可达 p.p.b 数量级(1p.p.b 是1千兆分子之一,即(1)/(1000×10~6)=(1/1~9)),线性范围也比较宽,可达10~4。它从灵敏度来讲,是目前所有的探测器*高的一种,它比*好的氢火焰电离探测器的灵敏度还可高出50倍。

  The helium detector is a kind of detector applied on a gas spectrometer with a simple structure and extremely high sensitivity to permanent gases (such as N_2, O_2, Ar, H_2, CO, CO_2, etc.). In addition to Ne, Almost all permanent gases can be measured. Its minimum detection volume can reach the order of ppb (1p.pb is one of 1 gigamolecule, that is (1)/(1000×10~6)=(1/1~9)), and the linear range is relatively wide, which can be Up to 10~4. In terms of sensitivity, it is the highest of all current detectors, and its sensitivity is 50 times higher than the best hydrogen flame ionization detector.
