CCDs Get One More Customer

Merck launches its new CellStream benchtop flow cytometry system that uses a camera for detection. Its unique optics system and design provide researchers with unparalleled sensitivity and flexibility when analyzing cells and submicron particles.

The CellStream system’s Amnis time-delay integration (TDI) camera technology rapidly captures low-resolution cell images and converts them to high-throughput intensity data with enhanced fluorescence sensitivity.

"The custom camera within CellStream flow cytometers operates using this TDI technique, whereby a specialized detector readout mode preserves sensitivity and image quality, even with fast relative movement between the detector and the objects being imaged. The TDI detection technology of the CCD camera allows up to 1000 times more signal to be acquired from cells in flow than from conventional frame imaging approaches. Velocity detection and autofocus systems maintain proper camera synchronization and focus during the process of image acquisition."
