  • Patent number: 11873407
    Abstract: A diketopyrrolopyrrole pigment compound having high weather resistance, a preparation method therefor and a use thereof, which relate to the technical field of organic pigments. The diketopyrrolopyrrole pigment compound has the structural formula (I). The described diketopyrrolopyrrole pigment compound may be directly used as a wet filter cake, or may be further formed into a flowing solid powder or granulated into a granulated preparation. In the various applications described, the diketopyrrolopyrrole pigment compound exhibits high saturation, good rheology, hiding power, and gloss, high tint strength, and particularly high weather resistance. The diketopyrrolopyrrole pigment compound having high weather resistance, the preparation method therefor and the use thereof have good market prospects.

  • Patent number: 11125687
    Abstract: A method for identifying fragmented red blood cells comprising: acquiring side scatter light signals and fluorescence signals of cell particles in a sample liquid; and distinguishing and identifying a fragmented red blood cell population from the cell particles according to the side scatter light signals and the fluorescence signals of the cell particles. The fragmented red blood cell population can be identified from the cell particles by processing and analyzing the side scatter light signals and fluorescence signals of the sample liquid. The present application further provides a device for identifying fragmented red blood cells, a blood cell analyzer and an analysis method. Fragmented red blood cells can be identified according to the fluorescence that characterizes a nucleic acid content in a cell particle and the side scatter light, thus reducing errors in identification and counting.
