Micrograph of paper autofluorescing under ultraviolet illumination. The individual fibres in this sample are around 10 μm in diameter.. Autofluorescence is the natural fluorescence of biological structures such as mitochondria and lysosomes, in contrast to fluorescence originating from artificially added fluorescent markers (fluorophores).
“As the first company to offer the ESP Detection Option on a cell sorter, we are setting a new standard for small particle research,” said Ming Yan, Ph.D., CTO of Cytek Biosciences. “The enhanced capabilities of our Cytek Aurora CS system not only push the boundaries of scientific discovery but also may open up new markets for Cytek.
Solid-phase extraction (SPE) [1] is a solid-liquid extractive technique, by which compounds that are dissolved or suspended in a liquid mixture are separated, isolated or purified, from other compounds in this mixture, according to their physical and chemical properties. Analytical laboratories use solid phase extraction to concentrate and ...
Extraction Profile for Different Types of Extraction. The extraction curve of % recovery against time can be used to elucidate the type of extraction occurring. Figure 4(a) shows a typical diffusion controlled curve. The extraction is initially rapid, until the concentration at the surface drops to zero, and the rate then becomes much slower.
Cytek’s FSP platform includes its core instruments, the Cytek Aurora™ and Northern Lights™ systems; its cell sorter, the Cytek Aurora™ CS; the Cytek Orion™ reagent cocktail preparation system; the Enhanced Small Particle (ESP™) detection technology, the flow cytometer and imaging products under the Amnis ® and Guava ® brands; and ...
A diagram of an electroextraction apparatus Figure 3. A diagram of a capillary electroextraction apparatus Electroextraction (EE) is a sample enrichment technique that focuses charged analytes from a large volume of one phase into a small volume of aqueous phase through the application of an electric current.

Aqueous samples, lysed cells, or homogenised tissue are mixed with equal volumes of a phenol:chloroform mixture. This mixture is then centrifuged. Because the phenol:chloroform mixture is immiscible with water, the centrifuge will cause two distinct phases to form: an upper aqueous phase, and a lower organic phase.
Laboratory-scale liquid-liquid extraction. Photograph of a separatory funnel in a laboratory scale extraction of 2 immiscible liquids: liquids are a diethyl ether upper phase, and a lower aqueous phase. Soxhlet extractor. Extraction in chemistry is a separation process consisting of the separation of a substance from a matrix. The distribution ...
