GC--FID 氢火焰检测器的应用实例的详细资料
氢火焰检测器的应用实例
氢火焰检测器的应用实例 详细信息:
氢火焰离子化检测器(FID)
高使用温度:400℃
小检出限:≤2.5*10 -12 g/s(n-C16)
线性范围:107(±10%)
噪声≤5×10-14A
漂移≤2×10-13 /30min
自动点火方式
包括:喷嘴,点火器,收集极,加热快,信号线,感温pt丝,室体等
氢火焰离子化检测器主要特点是对几乎所有挥发性的有机化合物均有响应, 对所有径类化合物 (碳数≥3) 的相对响应值几乎相等,对含杂原子的烃类有机物中的同系物(碳数≥3)的相对响应值也 几乎相等。这给化合物的定量带来很大的方便,而且具有灵敏度高(10-13~10-10g/s) ,基流 -小(10 ~10 A) ,线性范围宽(10 ~1 ) ,死体积小 ,响应快(1ms) ,可以和 毛细管柱直接联用,对气体流速、压力和很度变化不敏感等优点,所以成为应用广泛的气 相色谱检测器。

Application Examples of Hydrogen Flame Detectors
Application Examples of Hydrogen Flame Detectors Details:
Hydrogen flame io
nization detector (FID)
Maximum operating temperature: 400℃
Minimum detection limit: ≤2.5*10 -12 g/s(n-C16)
Linear range: 107 (±10%)
Noise≤5×10-14A
Drift≤2×10-13 /30min
automatic ignition
Including: nozzle, igniter, collector, fast heating, signal line, temperature sensing wire, chamber body, etc.
The main feature of the hydrogen flame io
nization detector is that it has a respo
nse to almost all volatile organic compounds, and the relative respo
nse values of all diametric compounds (carbon number ≥ 3) are almost equal. The relative respo
nse values of compounds (carbon number ≥ 3) are also almost the same. This brings great co
nvenience to the quantification of compounds, and has high sensitivity (10-13~10-10g/s), small ba
se flow (10~10A), wide linear range (10~1), dead volume Small size, fast respo
nse (1ms), can be used directly with capillary column, insensitive to gas flow rate, pressure and extreme changes, so it has become a widely used gas chromatographic detector.
