cytometer

A laboratory instrument for counting cells, especially blood cells. Originally, a glass slide engraved in tiny squares, on which cells had to be counted one by one by human microscopists, the modern version performs the task using lasers, digital electronics and graphics imaging technology. Flow cytometry is a powerful tool in modern medicine. Its applications have expanded from cell counting and sorting, to measurement of cell surface and intracellular antigens, and the analysis of DNA. Moderns cytometers can measure several parameters on many thousands of individual cells in a very short period of time.

However in the bead case, the measuring instrument, such as a cytometer, may sample over a limited range of emission wavelengths using various bandpass filters.
Sensors within the cytometer measure several parameters, including "low-angle forward scatter intensity," which is approximately proportional to cell diameter, and fluorescence intensities at several wavelengths, which allows for the study of cell components such as total DNA per cell, specific nucleotide sequences, and, by labeling with monoclonal antibodies, specific cellular proteins and other molecules.
