原ZIC-Ⅱ A型离子色谱仪中电抑制器的加液装置,是靠一个放在仪器顶盖上的电解液储液瓶将电解液加入电抑器中的。由于电解液中有H_2SO_4等强腐蚀性试剂,因此稍不注意就会腐蚀仪器的外壳,沾污工作台,甚至烧伤操作者的皮肤。另外控制流量也不方便,且硅胶管易在夹紧处断裂。 笔者根据操作经验,将以上加液方式改用一个医用 The former ZIC-Ⅱ A type ion chromatograph in the device to add electricity suppressor, is by a liquid electrolyte bottle placed on the top cover of the instrument will be added to the electrolyte in the suppressor. Due to H_2SO_4 and other strong corrosive reagents in the electrolyte, it may corrode the instrument casing, stain the workbench and even burn the skin of the operator. In addition the control flow is not convenient, and the silicone tube easy to break in the clamp. According to the author’s operating experience, the above method of adding liquid to a medical
