按照欧盟玩具安全标准EN 71-11,使用配置Agilent 7667A 微型热脱附仪的Agilent7820A 气相色谱仪和Agilent 5977E 气质联用仪,开发了一种测定挥发性有机化合物的经济型解决方案。10 种挥发性目标化合物在0.02 μ g 到2 μ g 的校准范围内具有极好的线性,而环己酮和异佛尔酮则在0.05 μ g 到5 μ g 的范围内具有极好的线性。使用此方法,在塑料玩具和毛绒玩具样品中加入目标化合物并进行测试。结果具有出色的重现性。
Fluorescence spectroscopy is an analytical technique with high sensitivity and selectivity. By characterizing the components in the EV-coat solution with fluorescence, a detailed analytical profile can be formed for each component. This can help trace the source of errors in the EV-coat solution, and contribute to selection of the best formulation. Quality-control tests can be performed periodically to check for consistent bath composition.
With the use of this fiber-optic adaptor and the pinhole adaptor, many microscopic fluorescence measurements can be achieved. Most microscopes, including Nikon, Olympus, Zeiss, and Leica, are compatible with the Microscope Adapter.
