| Term: | Flow Cytometer |
| Description: | A method to enumerate bacterial and phytoplankton cells in seawater and estimate their spherical diameter |
| Definition: | Flow cytometers are laboratory based instruments used to measure cells and particles from aqueous samples. The instrument was initially developed for analysis of Human blood cells for medical purposes, but this technology was adopted by the ocean science community by several investigators, principally Penny Chischolm out of the Massachusetts Institute of Technology, in late 20th century. Since then, the technique has been broadly applied, and it is a unique measurement of microbial populations in the ocean because it provides one at a time measures of cells, to extrapolate features such as fluorescence and cell size. Flow cytometers have been adapted for a number of oceanographic applications such as ship board measurement, and more precise measurement of planktonic fractions. Additionally, the flow cytometer has been adapted for in-situ deployment (see the corresponding nodc instrument code). |
