A modified comparison microscope assembly was developed for quantitative cytochemical analysis of stained or naturally pigmented objects. Test and control objects were photographed simultaneouslyon the same frame of color film. Pigments in the film image were then extracted and analyzed in a recording spectrophotometer. The total procedure is an extension and simplification of existing methods.
为了对染色或天然色素沉着的物体进行定量细胞化学分析，开发了一种改良的比较显微镜组件。测试对象和对照对象在彩色胶卷的同一帧上同时拍照。然后在记录分光光度计中提取并分析胶卷图像中的色素。整个过程是对现有方法的扩展和简化。
