Sysmex established a proprietary detection technology (capacitance method) by applying the principles of a megaphone and developed Japan’s first hematology analyzer, the CC-1001.
This technology is used to detect blood cells by measuring the changes in capacitance that occur when the cells are passed through an aperture. Later, we switched to an electrical resistance method using the same electrical principles. Since then, measurement accuracy has been dramatically improved by this technology. The electrical resistance method applies Ohm’s Law (voltage = current x resistance) and enables measurement of the types of blood cells and their numbers by converting changes in the electrical resistance when the blood cells pass through the aperture (pore) to the pulse signals.
At the time, this technology provided a dramatic increase in measurement precision.
