荧光光谱仪

Q: What is the difference between a fluorometer and a spectrofluorometer?

A fluorometer measures fluorescence intensity, while a spectrofluorometer measures fluorescence as a function of wavelength, providing complete excitation and emission spectra for more detailed analysis.

Q: Can one instrument perform both fluorescence and absorbance measurements?

Yes. Certain HORIBA systems, such as Duetta and Veloci , support both fluorescence and absorbance measurements within a single platform.

荧光光谱仪是指测量不同荧光物体发出的荧光或光。荧光发生时，特定波长的光激发样品使其激发，随后回落至基态过程中可发出不同波长的光。所有荧光物质都有独特的分子指纹图谱，这意味着其可被激发并发出可预测类型的光。

荧光样品产生的发射光谱通过连接到类似于分光光度计的光电倍增管检测器测量。

在激发样品后，荧光光谱仪可测量样品荧光的各种属性，包括光谱强度，波长和寿命。样品的荧光可以作为样品环境的间接探针，描述溶剂-溶质相互作用、分子间和分子内相互作用等。荧光可以用于样品的定性和定量分析。荧光光谱仪器提供的分析测量可用于多种应用，包括化学、生物化学、医学研究、制药、食品科学、环境研究和纳米技术。荧光光谱仪器已经被用于检测假钞、光电子材料和蛋白质研究等领域。
