Differences Between CASY and Coulter Cell Counting
A Coulter counter is one of the other devices used for cell counting. Like CASY technology, this also uses electric current for cell counting. However, the difference between them is that there is an aperture called “sensing zone”, with a known volume of electrolyte in a coulter counter. When suspended cells pass through it, they would displace the equivalent volume of electrolyte in the sensing zone and cause a short term change of electric current across the aperture. Since the circuit is to detect the change of current across it, any particles that can displace the electrolyte will be counted. It would be seen that the measurement of cells would be from a volume to another volume in the same sample.
In contrast, the CASY technology incorporates no electrolytic reservoir in the aperture and the cells in the electrolyte can pass through the measuring pore. It would be not necessary to detect the cells from a batch to another batch but measure them continuously and smoothly.

Famous quotes containing the words differences between, differences, coulter, cell and/or counting:
“The mother must teach her son how to respect and follow the rules. She must teach him how to compete successfully with the other boys. And she must teach him how to find a woman to take care of him and finish the job she began of training him how to live in a family. But no matter how good a job a woman does in teaching a boy how to be a man, he knows that she is not the real thing, and so he tends to exaggerate the differences between men and women that she embodies.”
—Frank Pittman (20th century)
“No sooner had I glanced at this letter, than I concluded it to be that of which I was in search. To be sure, it was, to all appearance, radically different from the one of which the Prefect had read us so minute a description.... But, then, the radicalness of these differences ... these things ... were strongly corroborative of suspicion.”
—Edgar Allan Poe (1809–1849)
“For in the word death
There is nothing to grasp; nothing to catch or claim;
Nothing to adapt the skill of the heart to, skill
In surviving, for death it cannot survive,
Only resign the irrecoverable keys.
The wave falters and drowns. The coulter of joy
Breaks. The harrow of death
Depends. And there are thrown up waves.”
—Philip Larkin (1922–1986)
“Why inspire in us a horror of our being?... To look upon the universe as a prison cell and all men as criminals about to be executed is the idea of a fanatic.”
—Voltaire [François Marie Arouet] (1694–1778)
“What culture lacks is the taste for anonymous, innumerable germination. Culture is smitten with counting and measuring; it feels out of place and uncomfortable with the innumerable; its efforts tend, on the contrary, to limit the numbers in all domains; it tries to count on its fingers.”
—Jean Dubuffet (1901–1985)
