增感染料是影响感光度的关键材料之一。由于它在乳剂层中含量少,稳定性差,属于难气化、易热分解的离子型化合物,应用常规质谱技术EI源无法得完整的结构信息。这一直是感光材料结构剖析中最困难的课题之一。本文就介绍了增感染料的剖析,作者经过简化操作,采用多种色谱方法,利用红外光谱微量技术,质谱EI源高分辨、低分辨,以及场解吸技术等准确地测定了相纸中的增感染料结构。
Sensitizing dyes are one of the key materials that affect sensitivity. Because of its low content in the emulsion layer, poor stability, are difficult to gasification, easy thermal decomposition of ionic compounds, the use of conventional mass spectrometry EI source can not get a complete structural information. This has been one of the most difficult issues in the texture analysis of photosensitive materials. This article describes the analysis of sensitizing dyes, the author through a simplified operation, the use of a variety of chromatographic methods, the use of infrared spectroscopy trace, high-resolution mass spectrometry EI source, low resolution, and field desorption techniques accurately determine the increase in photographic paper Infectious material structure.
