Abstract

A possibility of using a monitor calibrator for the determination of luminescent compounds is shown on an example of quinine. The determination is based on the irradiation of a sample with broadband radiation in the visible and near UV spectral regions from a built-in source exciting phosphor molecules and the simultaneous registration of the radiation incident on the detector. Measurement conditions are selected. Quinine can be determined in the range of 60−750 µM, the limit of detection is 20 µM. The determination is not affected by common inorganic ions, as well as sweeteners and acidity regulators present in many beverages. The developed method of determination is applicable to the analysis of carbonated drinks and drugs. Compared to a traditional spectrofluorimeter, monitor calibrator is characterized by compactness, mobility, ability of detecting luminescence in cuvettes of various sizes and shapes, and lower cost.

监测校准器作为分光光度计的替代品：饮料和药物制剂中奎宁的测定

摘要

奎宁的一个例子显示了使用监测校准器来测定发光化合物的可能性。该测定基于在可见光和近 UV 光谱区域使用宽带辐射从内置光源激发磷光体分子进行辐照，并同时记录探测器上的辐射入射。选择测量条件。奎宁可在 60~750 µM 范围内测定，检测限为 20 µM。该测定不受常见无机离子以及许多饮料中存在的甜味剂和酸度调节剂的影响。所建立的测定方法适用于碳酸饮料和药物的分析。与传统分光荧光计相比，显示器校准器具有紧凑、移动、
