A flow cytometry works like a microscope but with greater precision and accuracy. It is useful in examining and calculating the quantity of particles such as cells and chromosomes. The process requires the microscopic particles to be suspended in a stream of fluid and then passed through an electron detection apparatus. The process of collecting data from sample using the flow cytometer is termed 'Acquisition'. Acquisition is mediated by a computer physically connected to the flow cytometer, and the software which handles the digital interface of the cytometer.

The software is capable of adjusting parameters (i.e., voltage, compensation, etc.) for the samples being tested, and also assists in displaying initial sample information while acquiring sample data to ensure that parameters are set correctly. The technique is very useful in diagnozing health disorders especially blood cancer.
