喇曼微型探针,正式名称是分子光学激光检验器(Molecular Optics Laser Examiner,简称MOLE)。它是分析化学的一种在分子级工作的新工具。这就是为什么仪器名称冠以‘分子’一词。大多数超微量分析仪器是在原子级操作的,并不能提供化学键和分子构象的信息。如电子微探针能取得元素种类的信息,而不能说明其分子结构,甚至不能决定是无机物或有机物。这仪器用激光作单色光源,以照射置于显微镜的观测台上的试样之一小部份(从一至几百平方微米的面积)。从而获得这部份的喇曼光谱,以
Raman microprobe, the official name is Molecular Optics Laser Examiner (Molecular Optics Laser Examiner, referred to as MOLE). It is a new tool for analytical chemistry working at the molecular level. This is why the name of the instrument is labeled “molecule”. Most ultra-microanalysis instruments operate at the atomic level and do not provide information on chemical bonds and molecular conformations. Such as electronic microprobe can get the type of element information, but can not explain the molecular structure, can not even decide to be inorganic or organic. The instrument uses a laser as a monochromatic source to illuminate a small portion of the specimen (from one to several hundred square microns) placed on the microscope’s observation platform. To obtain this part of the Raman spectrum
