Put, the leacheate storage device connects the plunger pump, and the ion-exchange unit includes the use being arranged on splitter
To heat the heater of liquid in splitter, flow monitor, the flow rate detection dress are additionally provided with the splitter
Put and be electrically connected with warning device.
As the further improvement of such scheme, the flow monitor is arranged to small-bore fluid flowmeter.
As the further improvement of such scheme, the warning device is arranged to buzzer.
As the further improvement of such scheme, the flow monitor is electrically connected with LED display, the LED
Display screen is showing actual flow velocity that the flow monitor detects.
As the further improvement of such scheme, the flow monitor is electrically connected with control unit, the control
Unit is electrically connected with the plunger pump, to control the plunger pump work.
As the further improvement of such scheme, the sampling device includes elution liquid bath, de-ionized water tank, the elution
Liquid bath, de-ionized water tank are connected with solvent switching valve by pipeline, and the solvent switching valve connects the plunger pump by pipeline
Injection port.
As the further improvement of such scheme, described control unit is provided with a key cleaning button and a key is safeguarded and pressed
Button, described control unit safeguard that solvent described in button control switches Vavle switching type of solvent by a key cleaning button and a key.
The beneficial effects of the invention are as follows：
Compared with prior art, the present invention is provided with flow monitor on splitter, and flow monitor electrically connects
Warning device is connected to, when the flow velocity of liquid in splitter exceedes maximum allowable flow velocity, flow monitor control alarm
Device is alarmed, and reminds the flow velocity of liquid in staff's splitter to already exceed maximum allowable flow velocity, staff can incite somebody to action
Ion chromatograph is closed, to avoid splitter from causing to damage, so as to avoid ion chromatograph from locating always in much time using
The situation for exceeding allowable maximum velocity in flow velocity occurs, and plays a part of protection to ion chromatograph.The present invention can reach survey
The actual flow velocity of splitter is tried, reaches the purpose reminded staff and protect ion chromatograph.
Brief description of the drawings
The embodiment of the present invention is described in further detail below in conjunction with accompanying drawing, wherein：
