Static Electricity Removal by Ion Irradiation With the high-frequency AC corona discharge method, Shimadzu’s STABLO-AP ionizer provides a stable ion balance and excellent static removal performance on samples and containers. Precision weighing work becomes remarkably efficient. Electrodes are safely housed inside the unit.
AC Method Produces Excellent Ion Balance AC method: AC voltage is applied on the discharge needle and a well-balanced mixture of positive/negative ions is emitted in rapid alternation from one electrode. DC method: DC voltage is applied to a couple of electrodes. One is positive and the other is negative. Each electrode emits ions of one polarity only. An effective static removal angle is limited if the two electrodes are distanced. As electrodes deteriorate, initial ion balance is lost.
