X射线光谱学,作为一种应用最广泛的、非破坏性的元素分析技术,长期受到一个简单而重要的限制性因素的困扰,即:用液氮冷却的X射线探测器与外界环境隔离开来的、长期以来已经规范化了的窗口要吸收非常软的X射线,从而检测不到比钠轻的元素。这个限制性因素在电镜和X射线荧光(XRF)分析仪中至关重要;因为这些设备所分析的样品其中98%含有显著量的碳、氮,氧和(或)氟。为此,X射线光谱分析结果必然不完整。
X-ray spectroscopy, as one of the most widely used and nondestructive elemental analysis techniques, has long been plagued by a simple but significant limiting factor: the isolation of the X-ray detector cooled with liquid nitrogen from the external environment The window, which has long been normalized, absorbs very soft X-rays and therefore does not detect lighter elements than sodium. This limiting factor is crucial in electron microscopy and X-ray fluorescence (XRF) analyzers because 98% of the samples analyzed by these devices contain significant amounts of carbon, nitrogen, oxygen and / or fluorine. For this reason, the results of X-ray spectroscopy must be incomplete.
