研究了AlxIn 1-xSb发光二极管（LED）和光电探测器的特性，以确定它们对甲烷传感的适用性。使用这些组件，可以在特征吸收波长和4 μ m（用作参考通道的有吸引力的波长）处实现良好的信噪比值。估计甲烷检测的灵敏度极限约为400 ppm，积分时间为10 s，路径长度为5 cm。
The properties of AlxIn1-xSb light-emitting diodes (LEDs) and photodetectors have been investigated to establish their suitability for methane sensing. Using these components it is possible to achieve good signal-to-noise values at both the characteristic absorption wavelength and also at 4 ¿m, an attractive wavelength for use as a reference channel. A limit of sensitivity of approximately 400 ppm, with an integration time of 10 s and a path length of 5 cm, was estimated for methane detection.
