Abstract: An analyzer suitable for performing continuous gas analysis in ultra-high purity applications. The analyser combines a low-level emission source and a gaseous emission spectrometer (10) having a charge coupled device (CCD) diod e array as a detector. The CCD detector replaces one or more photomultipliers and narrow bandpass filters typically used in spectrometers. The analyser performs various processing operations to evaluate and eliminate the effect of background light level, or dark spectrum.

Abstract: An analyzer suitable for performing continuous gas analysis in ultra-high purity applications. The analyser combines a low-level emission source and a gaseous emission spectrometer (10) having a charge coupled device (CCD) diode array as a detector. The CCD detector replaces one or more photomultipliers and narrow bandpass filters typically used in spectrometers. The analyser performs various processing operations to evaluate and eliminate the effect of background light level, or dark spectrum.

Abstract translation: 适用于在超高纯度应用中进行连续气体分析的分析仪。分析仪结合了低电平发射源和具有电荷耦合器件（CCD）二极管阵列的气体发射光谱仪（10）作为检测器。 CCD检测器代替通常用于光谱仪中的一个或多个光电倍增管和窄带通滤波器。分析仪执行各种处理操作，以评估和消除背景光等级或暗光谱的影响。
